Low Voltage XLPE Copper Cable PVC Sheath SWA STA ATA Armored
Electrical Wire
0.6/1KV underground cable are mainly complying with iec 60502
standard, also can be produced according to OEM requirements and
other standards, such as bs standard, din standard, ASTM standard,
etc.
0.6/1KV underground cable is up to 1kv, cross-section area can be
up to 400 sqmm (copper or aluminiun conductor). Conductor long-time
operating temperature is 90 degrees. In short circuit, conductor
highest temperature should be not more than 250 degrees.
0.6/1KV underground cable Laying conditions: For lyaing under
ground with large different altitude, be able to bear external
machanical force and moderate pulling force.
