Low temperature self-limiting temperature electric tracer is favored by many users because of its small starting current and scientific heating mode. Since the limit temperature PTC effect, positive temperature coefficient of electric tracing band can automatically adjust the power output, automatic heating temperature limit itself, so it can be "a certain range" arbitrary truncated or extension, that is to say, since the limit temperature or the use of electric tracing band length to abide by certain principles, such as solar energy tracing band, for example, when using general length is not more than 30 m, which is based on a certain, since the limit temperature of electric tracing band using the longer the length, the greater the output of power, with tropical itself is a kind of heat tracing system, not to participate in the temperature of the heating medium to be partners, so it can withstand temperature in 65 ℃ or so commonly, (outer insulation is the withstanding capability of the fluorine plastic more stronger), when using length exceeds a certain limit, would be damaged by instantaneous starting current is too large electric tracing band, the use of long time will accelerate aging of electric tracing band, reduce the service life of tracing band, so choose in for civilian solar electric tracing band must choose to meet the requirements of heat tracing electric tracing band.



The use length of a single self-limiting temperature trace is not more than 30m. What if the length is not enough in the use process? Can through the junction box connected with the two with tropical, in some cases, such as the use of two with tropical length added up to no more than 30 m, if two are associated with the use of tropical length more than 30 m, are not allowed to use connected with terminal block, so to work overtime not only has damage to the electric tracing band, and may occur leakage, short circuit, there is a certain risk, particularly for solar energy more attention should be paid to do a good job in security measures, strictly abide by the relevant rules, the use of electric tracing band safe, safe use electric tracing band.
