Description The self-regulating heating cable 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.  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 durable, UV resist, better than PVC jacket.
