Description

A temperature-dependant resistive element between two parallel copper conductors regulates and limits the power output of the heating tape according to the ambient temperature. If the ambient temperature rises, the power output of the heating tape is reduced. This self-regulating property prevents overheating even when the tapes are overlapped. Thanks to the parallel design the heating tape can be cut and installed to any required length. The self-regulating heating tape is available with different power outputs and protective jackets. The protective outer jacket of either fluoropolymer or polyolefi n protects the copper braiding from corrosion and chemical impact. Two jackets under the protective braiding provide electrical insulation. The inner one of the two jackets is thermally fused to the heating element (bonded jacket).
The heating system must be designed to ensure that the maximum operating temperature of +65 °C (+150 °F) will not be exceeded when it is energized. When it is switched off, the heating tape can be exposed to a temperature of +85 °C (+185 °F), not more than 1,000 hours cumulated.
