Defrosting Heating Cable

The modern technologies the last 10-15 years allow using heating cables in many areas for a wide range of applications. That's why the cables have to comply with many requirements - high working temperature, insulation resistant to outer effects and UV rays, high reliability and safety, wide working temperature diapason. The best insulation at the moment for such application is PTFE /teflon/. It complies with all the requirements and its characteristics are perfect. 

Applications :

For snow melting and defrosting outer areas. The main requirement here is that the cables are pretty strong to work with high temperature and to be able to defrost quickly even in a very cold weather. Here is a photo of a stairway which is defrosted with such cable: Thermostat is not needed. The system is turned on and off with a simple switch when required.

Defrosting streets and waterpipes - high working temperature is needed again. Also te resistance should be resistant to very wide temperature diapason and resitant to the UV rays. The UV rays have very bad influence on normal PVC or rubber insulations. The PTFE insulation though is very resistant to the UV rays and to the temperature amplitudes. Here is a photo of a waterpipe that doesn't have such cables. You don't need a thermostat - you turn it on when  needed.
