JH-FSLe Self-regulation Heat trace Cable is formed by electrical polymer (plastic) and two parallel metal wires and insulating layer. Its characteristic is that electrical polymer has very high positive temperature coefficient "PTC", and already in mutual parallel connection, can automatically adjust output power with temperature changing, and automatically limit the heating temperature.
It also can be arbitrarily shortened or lengthened in a definite scope, and can be allowed to multiply cross or superpose without any anxiety about high temperature heat point or burning.
Therefore, the character of above stated zonary constant temperature is that it fits for the heated system, but the traditional power-limiting heater oppositely influences the heated system. So this series of heating cable's apply range is more widely, such as used in oil well heat tracing; fire pipeline heat tracing; solar energy water heater's heat tracing; heat-preservation and preventing frost function of long pipeline and tank container; water pipe preventing frostbite and heat preservation in construction industry; natural gas exploitation and transporting establishment, chemical industry; heat tracing in civil use such as used for producing electrothermal glove, electrothermal mouse, low-voltage electrothermal blanket and electrothermal blanket etc.
