JFC-port / 3 constant power electric heating belt series electric heating belt

Information source: Anhui Cable Group Views: 5254 Release time: 2014-04-10

JFC-port / 3 constant power electric heating cable consists of three parallel metal core wires of the same specification and length as the power cord and heating element. The three core wires are all set independently and achieve the effect of insulation. After the power is turned on, the star-shaped series load forms a uniform and continuous heating body, so it is also called a series electric heating cable . The advantage is that the output power is stable, the heating temperature is uniform, and the single root has a long use length. It is mostly used for heat tracing and insulation of ultra-long pipes and tanks.

JFC-port / 3 constant power electric heating cable


product structure
1. Metal core wire;

JFC-6 ~ 30 / 3J: Rated voltage 380 (660) V, rated power 6 ~ 30w / m, insulation resistance ≥100MΩ / hm, electrical strength 3500v / min, insulation layer material PFA, maximum temperature resistance 260 ℃, explosion-proof mark ExeIIT4, high maintenance temperature 90 ° C;
JFC-30-50 / 3J: rated voltage 380 (660) V, rated power 30 ~ 50w / m, insulation resistance ≥100MΩ / hm, electrical strength 3500v / min, insulation layer material PFA, maximum temperature resistance 260 ℃, explosion-proof mark ExeIIT4, high maintenance temperature 70 ℃;


JFC-port / 3 constant power electric heating cable is mainly suitable for long-distance pipeline anti-freeze insulation or temperature maintenance. The single length of the independent power point is from 300m to 3600m. The actual selection should be based on the length of the pipe, the amount of heat dissipation, the working voltage and the number of core wires.
