Model : VV22、VLV22 etc.
PVC insulated power cable is the traditional low-voltage power cable,mainly to provide AC voltage 3.6 / 6kV and below the level of transmission and distribution lines of current transmission. The main features of PVC insulated cable is relatively soft, long-term operating temperature is generally 70 ℃. Using round wire core can improve the long-term pressure level of insulation,using the true color insulation can increase the insulation level of the cable.
On the contrary, the use of fan-shaped conductor can reduce the size of the cable structure, reduce cable costs; But the increase in the impedance of the cable to reduce the transmission current,color separation insulation can be easy to recognize, convenient construction and maintenance,but the insulation performance of the cable decreases, increasing the imbalance coefficient of the line.
How to choose the product, the user can be based on specific circumstances and the use of environment to decide. As the PVC insulated power cable has many advantages, can be widely used in construction, residential, mining, urban power supply etc. and other fields.
The characteristics of PVC insulated with flame retardant, the use of special formula can reach the corresponding flame retardant grade, in some special occasions, in order to prevent a fire and secondary the happening of the fire, using the low smoke low halogen flame retardant cable, fire-resistant cable structure, make the cable with good flame retardant fire-resistant performance.
