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 cable is a power cable that it is used commonly , because the price is relatively low, and widely used in many fields.
Use features:
Long-term Allowable Working Temperature:not exceed 70℃;
Short circuit maximum operating temperature of cable conductor does not exceed 160℃ (the longest lasting 5 seconds);
Cable laying temperature not lower than 0℃.
Minimum bend radius of the cable laying (D for the cable outer diameter): Single core non-armored cable to 20D, multi-core non-sheathed cables 15D, single core armored - cables 15D, multi-conductor armored cable to 12D
According to the cable VV and VV22 armor can be divided into two types. The biggest difference between the two models is that without armor VV, VV22 models with armor.

| Note: the above list can produce flame retardant product (before the above products plus ZR model which represents the product of flame retardant).In limited range, the main features of the flame retardant type power cable is difficult to fire or after fire retardant,the cable is suitable to lay in hotels, railway stations, chemical, oil platforms, mines, power stations, subways, high-rise buildings and cable flame retardant requirements of the occasion. Addition to a common power cable characteristics,fire-resistant cable also running within a certain time,when in the event of a fire burning.Especially suitable for fire alarm, fire fighting facilities, fire emergency evacuation and other distribution systems. | ||||
