pi cable

With the development of science and technology and the improvement of industrial manufacturing level, higher requirements have been put forward for cable materials in high temperature environment. Polyimide high temperature cable as a new type of cable products, due to its excellent performance and wide range of application prospects and received widespread attention. In this paper, the definition, characteristics, advantages and applications of polyimide high-temperature cable will be elaborated in detail.

Polyimide high-temperature cable refers to the cable that adopts polyimide as the insulating layer and protective layer, which can maintain stable performance in high-temperature environment. According to the different uses and structures, polyimide high temperature cables can be divided into various types, such as heat-resistant polyimide cables, flame-retardant polyimide cables, low-smoke and halogen-free polyimide cables and so on.

Main features of polyimide high temperature cables

High temperature stability

Polyimide has high heat resistance, can be used for a long time in high temperature environment, not easy to aging, softening or deformation.

Abrasion resistance

Polyimide cables have good abrasion resistance, which can effectively reduce the wear and tear of cables in high temperature environments and prolong their service life.

Corrosion resistance

Polyimide has good chemical stability, can resist the erosion of most acids, alkalis, salts and other chemical substances, to protect the cable from damage.

Electrical properties

Polyimide has high insulation resistance and breakdown strength, and can maintain stable electrical performance under high temperature environment.

Flame retardant properties

Some polyimide high temperature cables have good flame retardant properties, which can reduce the spread of fire in emergency situations such as fire and protect the safety of people and property.

Advantages of polyimide high temperature cable

For high temperature environment

Polyimide high-temperature cables have excellent performance in high-temperature environments, which can meet the needs of high temperature, high heat and other special scenarios.

Improve the performance of equipment

The use of polyimide high-temperature cables can improve the operational efficiency and stability of the equipment, reduce the failure rate, and extend the service life of the equipment.
