Flexible power cables on voltage up to 660V
KGtp 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 - “Flexogran” composition on the base of styrene TPE. Insulated conductors have identification colouring. Drain wire is greenish-yellow.
STRAND - cores (2, 3, 4) are twisted. In five-core cables cores are twisted around TPE string.
SHEATH - black “Flexogran” composition on the base of styrene TPE.
NUMBER OF CONDUCTORS - from 1 to 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.
Electric resistance of insulation per 1 km of cable at 20°С should not be less than 10 МОhm.
Range of operational temperatures is from -60°С up to +75°C.
Cables resist to 98% relative humidity at an ambient temperature up to + 35°C.
Cables resist to solar radiation.
Bending radius of cables at installation should not be less than 8 overall diameters of cable.
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.
