1.Brief Introduction :
cable is Cu conductor PVC insulated PVC sheath Electric power cable for laying buildings,inducts , kin tunnels,direct in ground and under water,.
For laying indoors , in tunnels, in ducts. Able to bear extermal mechanical force but not large pulling forces. Single core cables are impermissible to be laid in magnetic ducts.
2.Operating characteristics:
Rated power-frequency voltage u0/u:0.6/1 KV
Max permissible continuous operating temperature of conductor 70
Max short-circuit temperature of the conductor shall not exceed (Max 5 seconds duration): cross-section of conductor 300 mm2
The anbient temperature under installations should not be below 0
The bending radius of single core cable should not be less than 20 times of the cable diameter ,the bending radius of multi-core cable should not be less than 15 times of the cable diameter
