Cold wire connected 12V Can Use 15 Meters Self-regulating Heating Cable PE Insulation Low Voltage PTC HeaterNew upgraded product, the max circuit lengthscan be 15 meters.TheDWK12-J730self regulating heating cable is with low voltage12V, can be powered by car, truck battery to install in the car or truck,for some heating applications, freeze protection, heat trace. It's very convenient and easy to install.The cable will not over heat, average temperature will be30~50 Cdegree.The self-regulating heating cable developed byMincois widely used in fire protection,petroleum,chemical industry, iron and steel, electric power and so on tokeeppipes,tanks warm and prevent frostbite, roof and gutter snow melting.There is a uniform core strip ofPTC materialbetween the two parallel metal busbars. When the two busbars at one end of the cable are connected to the power source, current flows laterally from one busbar through the PTC material layer to the other busbar. The PTC layer is a resistance heating body that is continuously 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, doesnot overheat,saves electric energy,and has arapid heatingtemperature. It can be arbitrarily cut and used within the longest use length of the electric heating belt, and can be overlapped and crossed.Cable structure:1. Copper-core wire: 7 * 0.30mm2.

Wrap the heating cable on water pipes or fastening straight on pipes, both are ok.Put the whole cable on the pipes and fasten it every 30~60cm with thermal tape or aluminum tape.2. Suggest to wrap a layer of rubber insulation on the pipe, enhance efficiency of the heating cable and save energy, also can protect the heating cables.If need accessories, please click the picture to buy.Heat shrinkable tube:Insulation tape:Heat resistant Glass fiber tape:Heat conduction BGA Aluminum adhesive tape:Rubber and plastic insulation layer:FAQQ:Self Regulating Heating? Best Choice Or Not?-------Self regulating heating cable controls the temperature is not too high nor too low compared to other heating devices, because the temperature is automatically adjusted. With explosion-proof, all-weather performance, high reliability and long service life. It can solve other difficult issues, such as: long-distance pipeline heat tracing, narrow space heating and so on. May be self regulating heating cable one-time investment is higher,but it is the most economical heating measures in long running._x005f_x000D_
