VV PVC insulated power cable (VV, VV22)
Scope of application:
PVC insulated power cables have good electrical and chemical stability. The utility model has the advantages of simple structure and convenient use, and is suitable for being fixedly laid on a transmission and distribution line with an AC 50HZ and a rated voltage of 1kV and below.
Features:
The long-term working temperature of the conductive core does not exceed 70 ° C, and the short-circuit temperature cannot exceed 160 ° C (maximum duration of 5 s). When the cable is laid, the temperature should not be lower than 0 °C, and the cable laying is not limited by the drop.

VV cables are a very common type of power cable, and because they are relatively inexpensive, they are widely used in many fields.
Use characteristics:
The long-term operating temperature of the cable conductor does not exceed 70 ° C;
the maximum operating temperature of the cable conductor does not exceed 160 ° C during short circuit (maximum of 5 seconds);
The ambient temperature of the cable laying is not lower than 0 °C.
Minimum bending radius when cable is laid (D is cable outer diameter): 20D for single-core unarmored cable, 15D for multi-core unarmored cable, 15D for single-core armored cable, 12D for multi-core armored cable;
According to whether the cable is equipped with 铠, it can be divided into VV and VV22 models. The biggest difference between the two is that the VV model does not carry 铠, and the VV22 model has 铠.

Remarks: The flame retardant type of the products in the above list can be produced (the ZR is added to the above product model to represent the flame retardant type of the product). The main characteristic of the flame retardant power cable is that it is not easy to catch fire or after the fire is only limited to a certain degree. Within the scope, it is suitable for laying in hotels, stations, chemical, oil platforms, mines, power stations, subways, high-rise buildings and other places where the cable has flame retardant requirements. In addition to the characteristics of ordinary power cables, refractory cables have the characteristics of ensuring normal power supply for a certain period of time in the event of fire. It is especially suitable for the distribution of fire emergency systems such as fire alarms, fire protection facilities, and emergency evacuation. |
