Cables220V 230V 240V No need Controller Water-proof Self Regulating Heating Cable, Prevent Pipe Freeze Heat Trace SystemThe self-regulating heating cable developed is widely used in fire protection,petroleum, chemical industry, iron and steel, electric power and so on to keep pipes,tanks warm and prevent frostbite, roof and gutter snow melting .There is a uniform core strip of material between the two parallel metal busbars. When the two busbars at one end of the cable are connected to the power , current flows laterally from one busbar through the material layer to the other busbar. The layer is a resistance heating body that is connected in parallel between the busbars to convert electrical energy into heat. The core strip resistance increases with temperature, reaching about 65 degrees, the resistance is so large that it almost blocks the current, and the core strip temperature reaches the high limit and no longer rises but automatically limits the temperature. The self-limiting temperature heating belt has uniform temperature, does not overheat , saves electric energy, and has a rapid heating temperature. It can be arbitrarily cut and used within the longest use length of the electric heating belt, and can be overlapped and crossed.The cable is designed for house water pipe and solar upper water pipe freeze protection requirement in winter, to maintain the water in pipes above 0 centigrade, and do not need a controller.The cable is very easy to install, suit for metal and plastic water pipes.We use the pure copper as the conductor, and the PE jacket, it's , UV resist, better than PVC jacket.Product name:water pipe heating cable/self regulating heat trace cableVoltage: 200V240VPower: 17W/m (5W/ft)@10Max working temperature: 60Min installation temperature: -40Start-up current: less than 0.6 A/mMin. bend radius: @20:25.4mm @-30:35.0mmStructure:1.
