Household purpose wires
PBVV, PBVVG under Belarus quality requirements 500017371.025-2002
Wires are designed for lighting mains and connecting of devices to AC nominal voltage up to 380V and 50Hz frequency.
PBVV — a wire with parallel conductors, PVC insulation and sheath.
PBVVG — a wire with parallel conductors, PVC insulation and sheath, flexible.
CONDUCTORS — copper, solid or multiwire.
INSULATION — PVC. One of insulated cores should have an identification colour. Greenish-yellow colour is for drain wire, cyan – for zero conductor. Insulated conductors are parallel.
SHEATH — PVC. Color of sheath is on agreement with customer.
NUMBER OF CONDUCTORS — 2, 3.
CONDUCTOR CROSS-SECTIONS мм²: 1,0; 1,2; 1,5; 2,0; 2,5; 3,0; 4,0; 6,0.
Electric resistance of PVC insulation per 1 km length at 20°С should not be less than:
- 7 МОhm for 0.75 mm² cross-section;
- 6 МОhm for 1,0; 1,5 mm² cross-sections;
- 5 МОhm for 2,0; 2,5; 4,0 mm² cross-sections;
- 4 МОhm for 5,0; 6,0 mm² cross-sections.
Operational temperature range is from - 40°С to +70°С
PVC insulation and sheath resist to cracking.
Wires do not extend combustion.
The fault-free operational time is not less than 12000 hours.
The delivery length should not be less than 100 meters, 10 m and more wire pieces are possible to deliver but not more than 10 % of total length of batch.
Average service life is 8 years.
