Wires and cables with PVC insulation for electric installations
PuVV, KuVV, KuGVV under Belarus quality requirements 16.705.501-2010
Installation wires are designed for power installations, for fixed wiring in lighting and power mains, and also for assembling of electric equipment, machines on nominal AC voltage up to 450/750V frequency up to 400 Hz or DC voltage up to 1000V.
PuVV — PVC insulated and sheathed copper wire.
KuVV — PVC insulated and sheathed copper cable.
KuGVV — PVC insulated and sheathed copper flexible cable.
CONDUCTOR — copper solid or multiwire.
INSULATION — PVC. Insulated conductors have identification colouring.
NUMBER OF CONDUCTORS — 1 - 5.
CROSS-SECTION of CONDUCTORS, mm2 0,50; 0,75; 1,0; 1,5; 2,5; 4; 6; 10; 16; 25; 35; 50; 70; 95; 120.
Electric resistance of insulation per 1 km of cable at 20°С should not be less than 1 МОhm.
Wires resist to an ambient temperature from -50°C to +65°С.
Wires resist to mechanical impacts, linear acceleration, bends, vibration, acoustic noise and mold fungi.
Wires do not extend combustion at single laying.
Bending radius of wires at installation should not be less than 10 wire diameters.
Permissible conductor preheating temperature should not be more than +70°C.
The delivery length is not less than 100 meters, 20 m and more cable pieces are possible to deliver but not more than 10% of total length of batch.
Average service life of wires is 20 years.
