PV3, PV4 — single-core wires with PVC isolation for electrical units.
APPLICATION
Wires of PV3 and PV4 are applied to electrical units at stationary laying in lighting and power networks, and also to installation of electric equipment, cars, mechanisms and machines on rated voltage to 450 V (to networks to 450/750 B) with a frequency up to 400 Hz or constant tension up to 1000 Century. Wires of the PV3 brand are intended for installation of sites of electric chains where bends of wires are possible. Wires of the PV4 brand are intended for installation of sites of electric chains where frequent bends of wires are possible

DESIGN
wires of PV3 and PV4
CONDUCTING VEIN of a wire of PV3 and PV4 — copper, much and wire
ISOLATION of a wire of PV3 and PV4 — from PVC of plastic compound, various flowers. The coloring is carried out continuous or drawing two longitudinal strips on isolation of natural color located diametrically. For the wires used only for grounding, isolation has a greenish-yellow coloring. Color of continuous isolation or the put longitudinal strips has to be stipulated in the order.
