Ordinary type | Flame resistant type | Designation |
KVV | ZR-KVV ZRB-KVV ZRA-KVV | Cu conductor, PVC insulated and sheathed control cables |
KVV22 | ZR-KVV22 ZRB-KVV22 ZRA-KVV22 | Cu conductor, PVC insulated, PVC sheathed and tape (steel wire) armored control cables |
KVVP | ZR-KVVP | Cu conductor, PVC insulated, PVC sheathed and copper wire braid control cables |
KVVP2 | ZR-KVVP2 | Cu conductor, PVC insulated, PVC sheathed and copper tape shielded control cables |
KVVP2-22 | ZR-KVVP2-22 | Cu conductor, PVC insulated, PVC sheathed, copper tape shielded and steel tape armored control cables |
Note: The control cable of flame retardant type is mainly used in the place where fire-proof performance is required. The cable compiles to the requirement of the combustion test of GB12666.5-90 or IEC60332-3:2000. The ZR, ZRA and ZRB represent, respectively, flame retardant Category C, Category A and Category B. The cable can be produced with steel tape or steel wire armor.
