What is a compensating cable?

The compensation cable is mainly used to extend the cold end of the multipoint thermal motor and mobile thermocouple, and is connected to the display instrument to form a multipoint temperature measurement system. The insulation and protective layer materials of compensation cables require special requirements. The raw material is high-quality fluoroplastic, and the compensation cable is produced using an overall continuous extrusion process. It has acid resistance, alkali resistance, wear resistance, and non combustible characteristics, and can work in water and oil environments for a long time. The working temperature of the compensation cable is within the range of -60-260 ℃.

The application range of thermoelectric coupling compensation cables is very wide, including multi-point connection of automatic temperature measurement instruments in industries such as power, metallurgy, petroleum, chemical industry, national defense, scientific research, etc.

Compensation cable classification

There are two types of compensation cables: heat-resistant and ordinary. There are two types of heat resistance levels, which can withstand the working temperature range of -65 ℃~+200 ℃ and -65 ℃~+260 ℃ respectively; There are two types of ordinary grade, which can withstand working temperature ranges of -40 ℃~+70 ℃ and -40 ℃~+105 ℃, respectively.

From the perspective of wire structure, there are two types of compensation cables: armored and unarmored. The diameter of the compensation cable designed with armor shall not be less than 12 times the outer diameter of the cable, and without armor, it shall not be less than 6 times the outer diameter. According to the GB12666.5-90 test, the flame retardant characteristics of compensation cables are Class A. Compensation cables with different structural materials have different allowable bending radii. Copper core compensation copper cables with shielding layers have a bending radius not less than 16 times the outer diameter, while compensation cables with other structural materials have a bending radius not less than 10 times the outer diameter.

What is the difference between compensation cables and ordinary cables?

The conductor materials of compensation cables are made of alloy materials that transmit thermoelectric electromotive force, and usually the compensation cables are directly connected to thermocouples; Ordinary cables are transmission cables used to transmit electricity and provide power, with most of the conductors being electrolytic copper with excellent conductivity.
