SELF REGULATING HEATING CABLE

The two copper conductors are located inside an extruded semi-conductive polymer whose resistance varies with the temperature. This characteristic is used to supply the required power in proportion to the process temperature and allows the cable to be overlapped without burnout as the power reduces to almost zero when the polymer temperature limit is approached.
This technology avoids destruction by overheating in case of poor installation (overlap or crossing of cables, passing through insulation, etc.). However, it is important to ensure that the pipe temperature does not exceed the maximum exposure temperature of the cable either when operating or switched off.
