Main characteristics of the cable KG

Decoding of the

marking The abbreviation CG stands for quite simply - the cable is flexible. If there is a prefix "n" in the marking, i.e. KGN, this indicates that the conductor is additionally protected by a rubber oil resistant shell, which makes it non-flammable.

There is also a variant of tropical execution( indicated in the documentation as KG-T), at which it is allowed to use the conductor in conditions -10С to + 55С and cold-resistant design КГ-ХЛ( -60С to + 50С).

With the decoding of the electrical cable marking KG figured out, we hope that everything is crystal clear. We also recommend that you familiarize yourself with the generally accepted marking of wires and cables! You can visually see the appearance of the conductor in the video overview below:

Design features

The construction of the KG power cable is as follows:

1. The live core is copper, multiwire and, of course, flexible. In the KG-T brand, the cores are tinned and correspond to class 5 GOST 22483.
2. The number of copper veins can vary from 1 to 5, and the cross section is from 1 to 240 mm2.
3. Insulation layer of rubber cores( rubber type RTI-1 or RTI-2-CL).The outer shell is represented by rubber insulation РШТ-2 or РШТМ-2.If the conductor is single-core, its protective layer is represented by a rubber of the RTTI type. A separating layer may be present in the form of a synthetic film.
4. The color marking of the cores fully complies with international standards.

You have learned the design of the KG power cable, now let's talk about the main operational and technical characteristics of the conductor.

Description of the main parameters of the

Of the most important characteristics, we can distinguish:

• rated voltage 660 V( alternating) and 1000 V( constant);
• alternating current frequency 400 Hz;
• operating temperature from -40C to + 50C( brand KG, about the temperature of the other varieties we mentioned above);
• maximum allowable heating of cores no more than 75оС;
• minimum bending radius 8 outer diameters;
• the maximum building length for a cross-section of veins up to 35 mm2 is not less than 150 meters and at a cross section greater than 50 mm2 not less than 125 meters;
• warranty period of 6 months;
• service life 4 years;
• tensile force 1 mm2 not more than 19.6 N;
• electrical insulation resistance is not less than 50 MOhm * km.

Of the remaining technical characteristics of the cable KG can be identified calculated mass, and the outer diameter of the conductor. In order to visually see these parameters for each individual product size, let's take into account this table:

By the way, the price per km of cable KG starts from 10 000 rubles( average cost of KG-HL 2 * 0.75 in online stores) and endsmark of 1 975 000 rubles( four-core KG-HL 3 * 185 + 1 * 95).

Scope of application

Well, the most interesting question for readers is Electrics itself - where is the power flexible cable KG used? This conductor is intended for connection to a network of mobile mechanisms. It can be used for laying, both indoors and outdoors. The use of an electric cable for stationary connection of installations is not allowed, including its laying under the ground. This is due to the fact that the insulation of the conductor is not capable of withstanding mechanical loads, and can be damaged even under the pressure of solid soils.

It is allowed to install a cable line outdoors on ropes and overpasses, if all security measures are taken. In addition, the cable, as we have already said, is frost-resistant, so it can be used even at sub-zero temperatures.

We draw your attention to the fact that there are also analogues of this electrical conductor. Instead, you can also use cable products labeled "KPG", "KPGS" or "KRPT".

The best producers of

The last thing I would like to tell you is which cable manufacturers are considered to be the best today. According to numerous feedback from customers, the products from manufacturers of KamKabel LLC and RybinskKabel OJSC have acceptable quality and the same price. The cable production of the Sevkabel GC is quite good quality.

That's all I wanted to tell you about the technical characteristics of the cable KG.We hope that now you know where you can use this guide, what kind of species it is and what is equally important - which manufacturers produce the best quality products!
