Its working principle is to compensate the heat-conducted pipelines by indirect or direct heat exchange through the heat radiated by the electric heating cable. The heat loss to meet the requirements of anti-freeze insulation, to ensure the normal use of fire pipes in the cold winter. The fire-fighting heating cable has the advantages of long service life, small starting current, good memory performance and low annual attenuation rate.
Second, Fire pipeline electric heating cable with the advantages of the tropical
1. Safety: Provide your maximum safety protection PTC characteristics and unique structure to ensure that the output power of the heating cable responds quickly to changes in ambient temperature, and there is no worry about local overheating.http://www.tiankangcable.com/Heat-Trace-Cable.html
2, Convenient: cut to any length according to needs, continuous parallel conductor structure and uniform heating medium distribution, constant power transmission per unit length, so it can be cut on site according to the required length.
3, energy saving: automatic temperature control is easy to install, self-temperature control characteristics, so that the output power automatically adjusts with the change of ambient temperature, no need to set up another temperature control system.
4, save trouble: after installation without maintenance, highly flexible structure allows you to use in any pipeline and connection parts, flame-retardant moisture-proof insulation structure design, so that you can install almost no maintenance.
Third, Fire pipeline electric heating cable structure
