Wires, Cables & Cable Assemblies

The heating of the unit length of constant power electrothermal cable is constant, the total output is bigger if the cable is longer, the length of electrothermal cable can be cut randomly according to actual demand. Meanwhile, it is flexible and can be convenientiy closed to the conduit surface for laying. The external metal shield net of electrothermal cable is used as safety earth wire to avoid static phenomenon, which doesn& acute;t only enhance integrated performance, but also acts function of heat transfer and thermolysis.
When the electrothermal cable is used with supporting control electrical apparatus, it can accurately calculate dielectric temperature maintaining conduit or heater.
Strengthened type electrothermal cable is coated with an insulation layer on the basis of general type electrothermal cable, with its rest structure totaliv the same with general type Compared with general electrothermal cable, strengthened type is with higher mechanical performance and anticorrosive performance, and it is applicable for occasion where contains corrosive gas.
As the section area ofbusbar is limited, so in order to avoid too much voltage drop, for single point power, the max length ofsingle way output should be selected as table l; for two-way output of single point power, the length can be added by one time, if needed heating cable is longer, then it can adopt multi-point power.
The electrothermal cable should be used with supporting control electrical apparatus, which owns protection function for overload, short circuit, earth leakage and temperature.
