PV-1 single-core copper wire, assembly, with PVC isolation for electric installations. PV1 wire is intended for laying in pipes, construction cavities, cable trays and under plaster. It is widely used both in production and at the household level. One of its main advantages is a very reasonable price with quite good technical characteristics.
The nomenclature of wires which are most in demand in installation is PV-1 section 1х0,5, 1х0,75, 1х1, 1х1,5, 1х2,0, 1х2,5, 1х3, the price accordingly is formed depending on wire diameter.
Decoding of wire PV-1:
P – It means that it is a wire.
The second letter B – means the type of wire insulation. In our case it is PVC insulation. It has stable physicochemical properties and is therefore often used as a dielectric.
The number “1” means the flexibility class. The lower this figure, the greater the bending radius can be exposed to the wire.
1. In the case of PV1 wires – copper, single-wire or multi-wire, class 1 for sections from 0.5 to 10 mm2 incl., Class 2 for sections from 16 to 95 mm2 incl.
The maximum outer diameters of the conductive cores of the wires are shown in the table below.
2. Insulation – made of PVC plastic, different colors. Staining is performed continuously or by applying two longitudinal stripes on the insulation of natural color, located diametrically. For wires used only for grounding purposes, the insulation is greenish-yellow. The color of the solid insulation or applied longitudinal stripes must be discussed in the order and has a symbol,
Wires are used for electrical installations with stationary laying in lighting and power networks, as well as for installation of electrical equipment, machines, mechanisms and machines at rated voltage up to 450 V (for networks up to 450/750 V) with a frequency of up to 400 Hz or DC voltage up to 1000 volts .
The wire of the PV1 brands is intended for laying in steel pipes, hollow channels of building designs, on trays, etc., for installation of electric circuits. The electrical resistance of a wire depends on its cross section. Thus, for a wire with a cross section of 0.5 mm2, the resistance should be not more than 0.015 Mohm, for the wire PV1 1 5 Not less than 0.011 Mohm, and for the wires PV1 120 not less than 0.0035 Mohm.
