Product description

Low voltage power cable 0.6/1 kV PVC insulated and vinyl chloride sheathed power cable

Product use

This product is suitable for power supply and distribution in lines with AC 50 Hz rated voltage of 0.6/1 kV.

Usage characteristics

The maximum rated temperature of cable conductor is 70°C.
The maximum temperature of cable conductor shall not exceed 160°C during short circuit (the longest duration shall not exceed 5 s).
When laying cables, the ambient temperature shall not be lower than 0°C. The minimum bending radius is: for single-core unarmored cables, 20 times the outer diameter of cable; for single-core armored cables, 15 times the outer diameter of cable; for multi-core non-armored cables, 15 times the outer diameter of cable, and for multi-core armored cables, 12 times the outer diameter of cable.

Cable operation and laying conditions

Cable laying

When laying, the cable temperature shall not be lower than 0°C, and when the ambient temperature is lower than 0°C, the cable shall be preheated.
The minimum bending radius for laying is: for single-core unarmored cables, 20 times the outer diameter of cable; for single-core armored cables, 15 times the outer diameter of cable; for multi-core non-armored cables, 15 times the outer diameter of cable, and for multi-core armored cables, 12 times the outer diameter of cable.
After the cable is laid, it shall undergo DC withstand voltage test for 15 minutes and the test voltage is 3.5 kV.

Laying in the air

When single-core cable is laid in parallel, the center distance is: for 185 mm and below, 2 times the cable diameter, and for 240 mm and above, 90 mm.
Ambient temperature: 30℃。
Maximum allowable temperature of conductive core: 70℃。

0.6/1 kV PVC insulated and sheathed refractory power cable

$0.6/1 kV PVC insulated and sheathed refractory power cable$

Product use

This product is used in high-rise buildings, subways, power stations and other important occasions with fire safety and fire lifesaving capabilities.

Usage characteristics

0.6/1 kV PVC insulated and sheathed refractory power cable is designed and produced according to GB/T12706-2008 (equivalent to IEC60502 standard), and its physical and electrical properties are the same as those of ordinary plastic cable. Its fire resistance meets GB/T19666-2005. That is to say, the cable can maintain normal operation for 90min under rated voltage of 0.6/1 kV and flame combustion at 750-800°C.
