Single-core wires with PVC insulation for electric facilities per GOST 6323- 79
PV-З is wire wuth Cu core and insulation from PVC compound, characterized by high flexible

PV-4 is wire wuth Cu core and insulation from PVC compound, characterized by highest flexible

CONSTRUCTION

1. CONDUCTING CORE:
   — PV-3 wires: Cu, multi-cores, class 2, 3 or 4 for cross-section from 0,5 up to 1.5 mm2 incl., class 4 for cross-section from 2.5 up to 4 mm2 incl., class 3 for cross-section from 6 up to 95 mm2 incl. per GOST 22483;
   — PV-4wires: multi-cores, class 5 for cross-section from 0,5 and 0.75 mm2, class 4 or 5 for crosssection from 1 and 1.5 mm2, class 5 for cross-section from 2.5 and 4 mm2, class А or 5 for crosssection from 6 and 10 mm2 per GOST 22483. 
2. INSULATION: from PVC compound various coloring. Coloring is continuous or of 2 longitudinal stripes put diametrically on insulation of natural color. The wires, used as grounding core have greenyellow coloring. The color of solid insulation or stripes should be bespeaced at ordering and have identification mark,

APPLICATION
Wires are apply for electric facilities at stationary cabling in lighting and power networks, and also for installation of electric equipment, machines and devices on nominal AC voltage up to 450 V (from networks up to 450/750 V) of frequency up to 400 Hz or DC voltage up to 1 kV.
PV-З apply for installation of electric networks, where the wire’s bendings are possible.
PV-4 apply for installation of electric networks, where the often wire’s bendings are possible.
