Flexible power cables on voltage up to 660V
KGV, KGVEV under Belarus quality requirements 05755944-005-93
Flexible power cables are designed for connecting of mobile installations and equipment to electric circuits and mobile sources of electricity on AC nominal voltage 660V frequency up to 400 Hz or DC nominal voltage 1000V.
CONDUCTOR — copper multiwire.
INSULATION — PVC. Insulated conductors have identification colouring. Drain wire is greenish-yellow.
STRAND — insulated cores (2, 3, 4) are twisted. In five-core cables cores are twisted around PVC string.
ZONAL INSULATION — PVC.
SHIELD — braid from copper wires with diameter no more than 0,26mm. Shield density is not less than 70%.
SHEATH — black PVC.
NUMBER OF CONDUCTORS — 2; 3; 4; 5.
CROSS-SECTION of CONDUCTORS, mm²: — 0,75; 1,0; 1,5; 2,5; 4,0; 6,0; 10,0; 16,0; 25,0; 35,0; 50,0; 70,0; 95,0.
Range of operational temperatures is from -40°C up to +70°C for temperate modification; from -60°С up to +70°C for cold modification.
Cables resist to 95% relative humidity at an ambient temperature up to + 35°C.
The cables with 2 - 5 cores and cross-sections up to 4 mm2 withstand not less than 30000 bending cycles.
The delivery length:
- for cross-sections up to 35,0 mm² is not less than 150 meters,
- for cross-sections 50,0mm² and above is not less than 100 meters, 20 m and more cable pieces are possible to deliver but not more than 20% of total length of batch.
Average service life of cables is not less than 4 years.
