Corrugated cable: the best solution for the installation of electricity

Manufactured articles obtained from the polymers ever more widely used. Ribbed corrugated cable used not so long ago, but it is the best option from all technological innovations to protect power grids. Lightweight, compact, and flexible ducts made of PVC retain their shape, displacing old technologies. The criteria for the selection and installation of protective features of the corrugations of the polymers is to understand more.

What is a polymercorrugated pipe for cable

Corrugation for wiring - is a flexible tube made of PVC. Because of its properties, including increased flexibility and elasticity, plastic products facilitate installation of electricity in remote and subjected to high load areas. For example, in houses built in seismic regions, with fluctuations easier to protect an isolated manner the wiring.

Protection in the form of pipes made of polyvinylchloride - it is also the possibility of combining several wires in one channel. This method is used for mounting a multicomponent complex wiring of lighting and suspended ceilings with combined lighting. Scope of the corrugated pipe is wide enough. Modern enterprises produce several varieties of products for special purposes.

Corrugated PVC pipe for a cable, generally small diameter, which eliminates the need Stroebe deep and wide channel for flush installation. It is available in rolls, in such packaging, it is convenient to carry and transport.

Important! Low prices for polyvinyl chloride - is insignificant surcharge for quality, reliability and speed of the wiring in the construction of new and reconstruction of old objects.

The polymeric materials from which the pipe for the cable is produced, have a lot of positive properties. For example, if there is a fire due to a short circuit, fast-extinguishing polymer prevents the spread of fire.

PVC pipe for wiring - it is also excellent insulation, and safety, which is important not only in residential buildings, but also in industrial environments. high voltage cable is much safer to lay the repair, knowing that the polymeric product protects against electric shock.

Corrugated wire and its most important properties

The corrugated structure is able to withstand tremendous pressure and mechanical stress, which can not show neither smooth tube under the same conditions.

Convenience corrugated PVC for wiring is not in doubt. The advantage of an isolated installation is still in the fact that it is easy to perform at any angle, even on the surface of the vaults and arches.

In tight spaces and on curves hidden line to make other way is very problematic. That product flexibility ensures quality installation electric cable with an exact repetition of complex curves in all the features of the architecture.

Flexible corrugated tube of a small cross section makes it possible to carry out installation of complex junctions and turns up to the turn 360 °. The cable attached to a hidden groove, fills it evenly, reducing the cost of plastering surfaces after the initial phase of installation.

In modern construction corrugated pipe mounted not only in buildings, but also outside them, that is application in the catering network for objects with outdoor lighting, especially in the countryside home ownership. For some time now the installation of electric systems rarely performed without the use of flexible insulation. In certain cases, accounted for landscaping. For example, it is recommended to use a red corrugated cable, which provides night illumination:

• paths and flower beds;
• pool or fountain;
• baths and saunas;
• artificial pond;
• area for barbecue and barbecue;
• cloister or terrace.

Ease of use - an important argument for the use of corrugated cable laying in the ground and outdoor applications. Its scissor on metal or other suitable devices.

Wiring through ripple:variety of flexible products

At the moment, the protective polymeric sleeve is available for different construction needs, including sewer corrugated and protection for cables of different voltages. Depending on the properties of the polymer and the size of corrugations cable experts recommend to apply it to various types of wiring:

• power cable;
• for low-power networks (telephone, television and computer UTP cable).

Protective corrugated, in accordance with the purpose, is available not only in the polymer, but also in a metal version. Flexible pipe products are of material, color and designs (for example, there is a double flute). Within the product's cable is pulled, sometimes even more than one - it all depends on the operating environment and the type of wiring:

• hidden inner;

• exterior;
• underground.

Useful advice! When buying pay attention to the thickness and cross-section of the corrugations, so as not to overpay for unclaimed property. The cable should easily pass through the inside of the sleeve.

There is another type of classification of products - according to the degree of strength:

• light pipes;
• heavy;
• superheavy.

Light bead is used for flush mounting inside the building (sensitive to UV light). Heavy and compact corrugated products are produced for laying underground (characterized by high resistance to pressure).

conditional color designation is used for the convenience of determining the destination, which is reflected in the table below:

№ p / p	color corrugations	Scope
1.	Gray	Standard electrically
2.	White	Computer networks, Internet
3.	Green	Telephone or other low voltage cables
4.	Red	External power electrocable
5.	Blue	The system "warm floor" and flexible vodogonah
6.	Yellow	gas supply needs
7.	Corrugated black and brown	Insulated wire appliances and other electrical appliances

This is a common industrial and building standards, but it does not always adhere to, especially if the remainder after a large amount of work there is a small supply of products, in coils.

How is the cabling in the ripple and dismantling if necessary probe

Before the advent of the protective flexible PVC pipes for electrical systems cable directly walled into a recess in the wall. Mounting complicated by the fact that the open ends are bolted to the bus or other support, the metal flows into the pipe segment. In emergencies or malfunctions cable was removed from under the plaster (with the risk of damage).

A careful study of the range of modern proposals in this field of application it becomes apparent that sold the usual hollow and corrugated product with an internal probe. It is often called "broaching" - and this is its purpose.

Useful advice! Think about how skip wire inside the sleeve. Best option, when the installation of the system it is possible to catch him and pull quickly.

The probe, if provided, is always visible inside the plastic tubes. A thick metal wire located inside the entire length. A protective sheath for wiring is cut together with the probe as needed.

Use proheavy very simple hooking the wire end of the probe, the cable is drawn through the entire length of the resin tube. The probe - a guarantee of comfort filling tube power cable. Simple engineering decision confirms the saying that all brilliant - just. Only to realize pulling the electric cable inside the corrugations at great length, we can appreciate the simplicity and wisdom of this decision.

On small-sized pieces of corrugated tubing (e.g., when there is a need for insulation wiring) the probe is not in use.

Attention! Doubtful savings do not justify the purchase without a probe inside the corrugated cable: the price differs insignificantly, and the work is slowed by almost half without a probe.

Ease of use of the corrugations is also the fact that the cable protection is performed without special tools and does not require much effort. It needs only the inner tube and tools for cutting, after which the cable is laid in the prepared furrows (Stroebe).

When dismantling the old wiring circuit corrugated sleeve optionally be removed from the grooves under the plaster. After removing the wires from the insulation cavity probe no longer required. Flute hidden in Stroebe, could it be that eliminate the need to make repairs. It is enough to extract the desired piece of electric cable by pulling on its end. Empty corrugation is recommended to fill in around the edges of the foam.

Technical corrugated cable and its classification

Variety corrugations cable diameters, differences in the cross-sectional thickness and can use it for different purposes.

Usual thin-walled products - lightweight, flexible, less pressure-resistant hose. Although they are applicable for both exterior and for interior works, often hidden in the sleeve of a specially prepared niche where there is no great pressure. The corrugations are also used:

• inside the frame and trim designs from GCR;

• in stretch and suspended ceilings;
• in a protective wiring cars;
• the installation of vertical metal poles.

Products Reinforced - heavy PVC pipes which are designed for a sufficient mechanical load, including temperature changes and complex operating conditions. They can be poured in concrete structures installed under a thick layer of plaster or under the ground at a shallow depth - with the transfer cable to the neighboring buildings.

Superheavy corrugation is designed to provide maximum protection from possible damage power grids. It is used in cases where wiring is laid in areas that require the highest level of security.

Parameters protective bellows for cable vary - within 16-50 mm outside diameter and from 10.7 to 40.2 mm in internal size.

Recommendations for choosing a product according to its diameter:

• closed loop thin wires connecting to coaxial networks, sockets, computer and telephone networks, the installation of electrical and signaling enough diameter 20 mm;
• wiring between distribution boxes and connection electroboards performed using 32-35 mm diameter articles;
• Cable connection between floors - up to 40-50 mm.

Material sold in coils of 25 - 100 m, most of the probe or broaching to facilitate filling of flexible hoses. For easy transportation of the bay is packed in shrink plastic.

Variety of materials:

• a conventional PVC (polyvinylchloride extinguishing);
• most plastic HDPE (High Density Polyethylene) to be used on rotary and curved sections of the construction;

• LDPE (high pressure polyethylene) flush stacking in solid materials, not prone fire, also polyethylene is used for making a two-layer outer shell corrugations;
• PA (polyamide) with maximum protection against moisture;
• PP (polypropylene) for cable channels in the monolithic structure.

Areas of application of the polymer corrugations superheavy

Extra heavy PVC pipe cope with the increased load and the pressure when laying into the ground to a sufficient depth. It can protect the communication under the roadway and the foundation of the building, near the bridge supports and fences. The price of cable laying in the ripple increases insignificantly, mainly due to the cost of more expensive, thick-walled tube used for the exterior.

If thin corrugated hoses are laid under plaster vertical walls, the large format hide in a concrete ditch - under the roadway, paved parking.

Useful advice!It makes no sense to buy such products because of the high reliability of extra-heavy corrugations, if you do not involve complex operating conditions.

It is better to buy a PVC product in accordance with specifications or to pick up the metal corrugated cable, if the probability of increased load.

The choice of this type of product may be dictated by security concerns, when it comes to laying the mains in buildings designed for a large crowd of people, such as:

• schools and other educational institutions;
• shopping centers;
• hotels;
• hospital facilities;
• industrial buildings monolithic type;
• railway stations and other transport infrastructure.

The high flexibility of extra heavy corrugated pipe allows the use of cables to rotary and curved sections for different purposes. These products are used for additional insulation of the wiring against moisture, chemicals and mechanical stress. Polymer corrugation outdoor cable has a high fire safety, especially if made of self-extinguishing PVC. It prevents the spread of fire by a sudden inflammation due to possible accidents.

Classification of PVC products and metal hose for the cable on the level of fire safety

Recently enhanced requirements for use in the construction of infrastructure in fire-resistant materials. Experts recommend the use of corrugated pipe for cable, based on the degree of fire safety:

1. For laying inside nonflammable structures (concrete, brickwork, concrete frame, monoliths) are applicable any corrugated sleeve.
2. The hollow structures made from noncombustible materials can be used corrugation that does not support combustion (PVC, LDPE and the metal protection).
3. Mounting inside overlap of flammable materials (wood paneling, plasterboard, composite boards) requires the use of a fire-resistant pipe, preferably with a special impregnation. Flammable plastics may not be used under such conditions.
4. Open broaching cables made from materials flame-retardant (installation is made on a distance from flammable coatings).
5. Corrugation of self-extinguishing polyethylene (LDPE) and polyamide (IPA) is used for wiring within an outer rigid structures.

Attention! Laying of electricity in hazardous buildings made of flexible metal hose inside and protected from the magnetic field of materials. Plastic pipes, GOST, respectively, are not designed for this purpose.

Properties of electrical double-walled corrugations

When selecting products for construction purposes it is important to pay attention to technical parameters and certifications. It is considered the most reliable bi-amplification tubes of different polymers having:

• external ribbed coating;
• smooth inner layer.

These structural differences contribute to the strength and ductility of these products. Enhanced bandwidth provides a smooth inside wall of IPA sleeves that match the cable diameter. Products are available in the "classical" and combined (plus HDPE LDPE) forms.

The reinforced structures foil (metal) layer may be used. This provides protection against excessive load and mechanical pressure. Rigid double corrugation guarantees high rigidity coefficient amplified gofrorukav HDPE is discharged with a large cross section. These tubes are designed for harsh environments - and under the soil within a raised floor, under tension inside the floors and cement screed.

Important!Electrical smoking corrugation used for conveying liquid media, e.g., for feeding in outside shower or hot water boiler. For such purposes it is better to use a two-layer metal pipe segment.

Advantages and disadvantages of corrugated HDPE pipes

Each of the polymer product has its undeniable advantages and disadvantages. Among the advantages of protective sleeves experts note:

• resistance to large temperature range (from -30 ° C to +90 ° C);

• easy installation corrugations at any time of the year and in difficult climatic conditions;
• sufficient tensile strength due to the stiffeners;
• affordable installation and easy pulling of cables in the ripple for interior and exterior use;
• laying ductility provides any contour, in most cases without fittings;
• in case of emergency and partial destruction of the structures of the corrugation is slightly expanded or narrowed, so that the cable does not break in;
• Polymer resistance to corrosion, chemicals and soils of different pH;
• long service life (40-50 years);
• access (if we talk about the ripple metal cable 16 mm, price per square meter is 11-15 rubles.).

Among the possible disadvantages:

• weak resistance to the damaging effects of ultraviolet in the external wiring;
• the risk of fire in an unprotected plastic.

How is the installation:clips for corrugated

For the installation of the corrugated structure offers ample range of accessories, including a probe for broaching and clips for corrugated 16 mm - price within 5 rubles per 1 pc.

Plastic brackets for mounting can be combined with nails, if for such a mounting surface of the material is suitable.

Important! The cost of laying cable in the ripple is relatively small - it is insignificant impact on material costs by replacing all systems.

The cutting grooves (grooves inside walls) produced by rapidly solidifying stacking solutions (starting plaster or stucco).

Special clips for surface mounting are produced in various formats - given diameter pipe, for example, clips for the corrugations 20 mm. Perhaps the use of clamps, left over from the construction and installation works, especially for placing inside ventilation ducts and other communications when combined.

Protected installation of hidden communication it is possible to organize their own hands if the corrugated product correctly matched in diameter. For this pre-Stroebe wall, making special markup tools to get the groove. The estimated price of cable laying in the ripple of the linear meter specifies a specialist construction firm. The size and cost of laying cable in the ripple in the estimates are recorded in advance.

Outdoor cable installation type performed for the walls of the FCL and stretched canvas using special clips and staples. They are placed at regular intervals, excluding sagging on a horizontal surface. Cable inside the floor heating is mounted on a special grate.

As you can see, before the acquisition of protective products for wiring necessary to consider all the characteristics and determine how to stretch the cable in the sleeve. When installing electric cables inside the corrugations on a large segment of the probe desirable to simplify the broach. Super-heavy double flute is only suitable for laying underground cable inside the floor with the increased load. In a domestic environment for available light self-assembling product if the cable section is smaller than the diameter of corrugated tube.
