Description
A temperature-dependant resistive element between two parallel copper conductors regulates and limits the heat output of the heating cable according to the ambient temperature. If the ambient temperature rises, the heat output of the heating cable is reduced. This self-limiting property prevents overheating even when the cables are overlapped. A temperature limiter is not generally necessary not even for Ex areas.Thanks to the parallel power supply the entire heating circuit is supplied with 230 V which allows the heating cable to be cut and installed to any required length. BARTEC-HEAT PSB is available with different power outputs and outer protective covers. The protective outer jacket of either fluoropolymer or polyolefin protects the inner copper braiding from corrosion and chemical attack.
The copper braiding serves as an earth conductor in accordance with VDE 0100 and also increases the mechanical stability of the cable. Under the protective braiding are two synthetic jackets providing electrical insulation. The inner of the two jackets is thermally fused to the heating element (bonded jacket).
