The marking of PV-1 stands for quite simply: "P" is wire, "B" is PVC outer jacket, "1" is the vein flexibility class( more rigid).This marking fully complies with GOST 6323-79, however according to another standard - GOST R 53768-2010, the conductor has the marking PU( installation).Next, we will provide readers of the Electric Electric website with the technical specifications of the PV-1 wire, and also describe what it is used for.

- Application area
Basic parameters
The design of the PU is as follows:
- Single, copper, multiwire / single-wire( tinned);
- insulation - PVC plastic;
- color marking is made according to GOST( colors can be yellow-green, white, red, blue, brown and even black);
With regard to the technical characteristics of PV-1( also PUV), the main ones are:
- Voltage 450/750 V( alternating) or 1000 V( constant).
- Frequency 400 Hz.
- The cross-section of current-carrying veins is from 0,5 to 120 mm.kv.
- Operating temperature from -50 ° С to + 70 ° С( but the gasket is allowed at a temperature not lower than -15 ° С).
- Electrical resistance not less than 1 MOhm * km
- Minimum bending radius 10 outer diameter of the wire.
- The building length is not less than 100 meters.
- Warranty period 2 years.
- Service life of 15 years.
We have provided the weight of the PV-1 wire and the outside diameter in the table below:
Also all the main parameters you can see on the video overview below:
Description of all the most important technical characteristics we have provided to you. It remains only to tell where this type of conductor is used and who produces it for today.
Application field
Due to the fact that the mounting wire PV-1 is resistant to mechanical damage, mold damage and also has self-extinguishing insulation, it is recommended to use it in power and lighting lines for the following purposes:
- Installation of electrical wiring in pipes.
- Line laying in hollow channels of building structures.
- Electric wiring in trays.
- Earthing of electrical installations.
In addition, it is allowed to use this conductor as an internal component of products only if condensation is prevented at these locations.
Finally, I would like to note that at the present time, the brand of PuV( analog) produces a lot of manufacturers, including such manufacturers as Belaruskabel, Kamsky Cable, and Kavkazkabel.
This is all you need to know about the technical characteristics of the PV-1 wire and its main purpose. If you have any questions, ask them in the comments or on our forum - the group in the conatte.
