Main characteristics of the wire PV-1
The marking of PV-1 is deciphered quite simply: “P” is a wire, “B” is the outer shell of PVC, “1” is the flexibility class of the core (more rigid). This marking is fully consistent with GOST 6323-79, however, according to another standard - GOST R 53768-2010, the conductor is marked PuV (installation). Next we will provide the site readers Elecroexpert technical characteristics of the PV-1 wire, and also we will tell what it is used for.
main parameters
The design of the PuV is as follows:
- single core, copper, multiwire / single wire (tinned);
- insulation - PVC compound;
- color marking made in accordance with GOST (colors can be yellow-green, white, red, blue, brown and even black);
As for the technical characteristics of PV-1 (aka PuV), the main ones are:
- Voltage 450/750 Volts (AC) or 1000 Volts (DC).
- Frequency 400 Hz.
- Cross section of live conductors from 0.5 to 120 mm.kv.
- Operating temperature from -50 ° С to + 70 ° С (but laying is allowed at a temperature not lower than -15 ° С).
- Electrical resistance of at least 1 MΩ * km.
- Minimum bending radius 10 outer diameters of the wire.
- Construction length at least 100 meters.
- Warranty period of operation 2 years.
- Service life is 15 years.
We provided the weight of the PV-1 wire and the outer diameter in the table below:
You can also see all the main parameters in the video review below:
A description of all the most important technical characteristics we have provided you. It remains only to tell where this type of conductor is used and who produces it today.
Application area
Due to the fact that the assembly 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 wiring in pipes.
- Laying lines in the hollow channels of building structures.
- Wiring in trays.
- Grounding electrical installations.
In addition, it is allowed to use this conductor as an internal element of products only if condensation is excluded in these places.
In conclusion, I would like to note that at present, PuV (analog) wire is produced by many manufacturers, including manufacturers such as Belaruskabel, Kamsky Kabel, Kavkazkabel.
This is all you need to know about the technical characteristics of the PV-1 wire and its main purpose. If you have questions, ask them in the comments or on our forum for electricians.
