RVV is Copper conductor PVC insulated and sheathed flexible cable, commonly known as Soft-sheathed cable, is one kind of sheathed cable.RVV wire and cable is consisted of two or even more RV lines plus one jacket outside. according to the choice of different materials,RVV wire is also divided into fire-retardant wire (ZR-RVV), fire-resistant wire (NH-RVV),low smoke halogen free wire (WDZ-RVV).Users can choose according to their own needs depending on different occasion. The low smoke halogen free wire and produce a very small amount of smoke in the flame, the release of gas does not contain halogen (low halogen) elements, non-toxic (low toxicity). When a fire occurs, it can greatly reduce the damage of apparatus, equipment and the human body.That's why it has been widely used in high-rise buildings, hospitals, large library, gymnasium, disaster prevention and control building, railway stations and civil airports, passenger waiting room, key cultural relics protected places and subway, underground shopping malls or densely populated public places. In addition, it can also be used for control signal transmission line, electrical equipment, instrumentation, automation equipment, security alarm system, high-rise building intercom systems, home lighting cable etc.1.Max Long-time operating temperature of PVC insulated cable is 70°C,XLPE 90°C 2.Installing temperature of cable should not be less than 0°C 3.Max short-circuit temperature is:PVC not exceed 160°C,XLPE 250°C,Not more than5 Sec. 4.Permitting bending radius cable: Not less than 10 D times (D:external diameter of cable) 5.Perfect chemical stability, resistant against acids, alkali, grease and organic solvents, and flamer retardant.
