Zhengzhou ZMS Cable Co. Limited

Pvc insuated power cable and fire resistant cable for laying in shaft, with large difference of level.

pvc insuated power cable and fire resistant cable not only has excellent electric, mechanical properties, but also has powerful resistance against heat aging, environmental stress and chemical corrosion. Its structure is simple and convenient to use and can be laid with no restriction of different elevation. The permissible maximum operating temperature is 90. Our xlpe cable can be produced according to our company standard which is equivalent iec60502. We can design and manufacture special xlpe cable according to the required by the customers. it is used to transmit and diatribuute power on the power line,u₀/ u₀ is ac rated voltage 0. 6/1kv exexutive standard gb/t12706-2008(equivalent iec 60502-1) rated voltage 1kv(um=1. 2kv) power cable working conditions: 1) this maximum workying temperature of the conductor is +70 2) durign having a short (lasting less than 5 seconds) the maximum temperature of the cale conductor shall not be above +160 3) environment temperature should be no lower than+0 for laying the cable 4) bending radius allowance of the cable single core cable: no steel tape cable 20d: steel tape cable 15d 3 cores cable :no steel tape cable 15d :steel tape cable 12d. notes: d practical external diameter of cable. the main technique function of the cable 1) cable conductor dc resistance: see the table1-2 2) ac voltage test; test voltage:3. 5kv,test time: 5min, the insulation has on puncture 3) constant of insulation resistance: +20 minimum 36. 7mω·km +70 minimum 0. 037 mω·km
