Power cable with PVC insulation and sheath |
To be laid indoors, in the tunnel, cable furrow or pipe. The cable can not bear mechanical force from outside. |
VV22 |
VLV22 |
Power cable with PVC insulation, PVC sheath and steel tape armored |
To be laid underground, the cable can bear certain mechanical force, but it can not bear great pulling force. |
Note:
1: We also produce flame-retardant fire resistant type power cable according to the requirement of the customer. Prefix "ZR" should be added to the original type of cable in ordering flame retardant cable; prefix "NH-" for fire resistant cable.
2: We also produce VV32, VLV32 type steel wire armored power cable according to the requirement of the customer. Magnetism-separated measure shall be adopted by single core steel wire armored cable.

Note:
1: We also produce cable with five cores according to the requirement of the customer.
2: Non-magnetic metal tape wrapping should be adopted as armored layer for single core armored cable for A.C. system.
E. Main Technical parameter of cable
1,Max value of conductor DC resistance shall meet the requirement of conductor of category 2 stipulated in GB/T3956 standard at 20ºC.
2,A.C. Voltage Test
For single core cable without shielding, voltage test of 3.5kV under power frequency is put on for 5 minutes between conductor and water when be immersed in the water for one hour. For multi-core cable, between each insulated conductor and other conductor, voltage test of 3.5kV under power frequency is put on for 5 minutes without puncture of insulation.
