Product features of KVV22 armored control cable:
1. Usage: This product is used for wiring electrical appliances and instruments in distribution devices with rated AC voltage of 450V/750V or DC voltage of 1000V and below.
2. Product usage characteristics: The long-term allowable working temperature of cable conductors should not exceed 70 ℃. The temperature of the cable during laying should not be lower than 0 ℃, and the bending radius during laying should not be less than 10 times the outer diameter of the cable. Cables with armor layer or copper tape shielding structure should not be less than 12 times the outer diameter of the cable.
3. Product standard: GB9330.2-88 "PVC insulated and sheathed control cables"
KVVP2 copper core PVC insulated copper tape shielded PVC sheathed control cable; Used in weak current control systems or strong electromagnetic field interference areas.
KVVP2-22 copper core polyvinyl chloride insulated copper shielded steel strip armored polyvinyl chloride sheathed control cable; Used in weak current control systems or strong electromagnetic field interference areas.
KVVP2-22-1 Copper core PVC insulated copper tape shielded steel tape armored copper wire PVC sheathed control cable; Mainly used in the strong electromagnetic field interference area of 500KV substations.
Note:
1) Add ZR - before the regular type for the resistance type cable number; The main characteristic of flame-retardant type is that the cable is not easily ignited or the ignition delay is limited to a certain range, suitable for occasions with high requirements for flame retardant performance.
2) Add NH - before the ordinary type for fire-resistant cable models; The main characteristic of fire-resistant cables is that they can not only transmit electricity under normal working conditions, but also maintain normal operation for a certain period of time during fire and combustion, making them suitable for situations that require fire resistance.
3) Low smoke and low halogen flame-retardant cable models with DDZ - added before the regular type; The characteristic of low smoke and low halogen flame-retardant cables is that they not only have flame retardant properties, but also have lower smoke generation and gas release. They are suitable for situations where there are certain requirements for the smoke concentration and gas release of cable combustion.
