Specification:
The self-regulating heating cable developed by Minco is widely used in fire protection,

There is a uniform core strip of PTC material between 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, does not overheat, saves electric energy,and has a rapid heatingtemperature. 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 durable, UV resist, better than PVC jacket.

Now buy DWK-J720 heating cable of more than 10 meters, we will give a set of connecting sleeves as gift!!!

2 pcs Heat Shrinkable Sleeves and 2 pcs Copper Tubes for each 10meters

Tips:

the heating cable in this link does not have a sealed end, thank you for understanding.

Product Pictures:

The self regulating heating cable is widely used for pipe/tank freeze protection, such as water pipe, solar water heater pipe, oil pipe, downspout.

For roof snow melting

tank electric heat tracing

water pipeline antifreeze

road snow melting and other heating applications.

Installation:

1) Seal the end of the cable with heat shrinkable tube or other electrical insulating tape.

2) Connect the other end with cold wire or plug (for connecting to the power supply).

3) 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(sold in my store).

4) 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.

5) Connect or plug into 200~240V. The heat trace system is finished.

Q: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.
