Full name PVC insulated PVC sheathed steel tape armored power cable
VV22 is a PVC insulated PVC sheathed steel tape armored power cable; the first V is PVC insulated, the second V is PVC sheathed, and 22 means a steel tape armored power cable, complete The expression is VV22-voltage level, the number of cable cores X the cross-sectional area of cable cores, such as VV22-1KV 5X50+240.
Features:
1. The long-term maximum working temperature of the cable conductor shall not exceed 70°C.
2. When short-circuited (the longest duration does not exceed 5S), the maximum temperature of the cable conductor does not exceed 160°C.
3. The ambient temperature when laying the cable is not lower than 0°C, and the minimum bending radius is 20 times the diameter of the cable.
Conditions of Use:
VV22 cables are suitable for direct burial underground, and can be laid indoors, in cable trenches, tunnels and pipelines. The cables can withstand certain mechanical external forces, but cannot withstand large tensile forces.
Number of cores: one core (single core), two cores (dual core), three cores, four cores (including "3+1" and fourth cores), five cores (including "4+1", "3+ 2” and fifth core).
