Power cable is used for transmission and distribution of electrical energy cable, power cable is commonly used in urban underground power grid, power station lead lines, industrial and mining enterprises internal power supply and underwater transmission lines across the river and sea.
Mainly used in the generation, distribution, transmission, transformation, power supply lines in the transmission of strong electrical energy, through the current (tens of amps to thousands of amps), high voltage (220V to 500kV and above).
First, the power cable voltage classification:
Power cables by voltage level: medium, low voltage, high voltage, ultra-high voltage, ultra-high voltage cable.
- Low-voltage power cables (35 kV and below).
- Medium voltage power cables (35 kV and below).
- High-voltage cables (above 110kV).
- Ultra-high-voltage cables (275-800 kV).
- Extra-high-voltage cables (1000 kV and above).
Next, TST CABLES focus on the more widely used medium and low voltage H-class (180 ° C) power cable characteristics and applications.
Second, low and medium voltage class H (180 ° C) power cables
Medium and low voltage H class (180 ° C) power cables, refers to the ability to work in a high temperature environment at 180 ° C, the cable belongs to the medium and low voltage cables, its rated voltage is usually between 1kV and 35kV. This type of cable is usually used where high temperature tolerance and higher voltage transmission is required. The main structure of a medium voltage cable consists of the conductor, insulation and sheath. In order to meet the requirements of high temperature and high voltage, these cables usually use special insulation materials and structural design.
Third, low and medium voltage class H (180 ° C) power cable technical characteristics
- High-temperature performance: Class H power cables can maintain stable electrical and mechanical properties in a high-temperature environment of 180 ° C, to ensure that the cable in a high-temperature environment, reliability and safety.
- Voltage level: The rated voltage of medium and low voltage H-class power cables is usually 35 kV and below, which is suitable for medium and low voltage power transmission system.
- Insulation material: In order to meet the requirements of working in high temperature environment, medium and low voltage class H power cables are usually made of high temperature resistant insulating materials, such as polyimide and PTFE.
- Conductor materials: the conductor of the cable is generally used in high conductivity copper or aluminum materials, in order to reduce the power loss in the transmission process.
Fourth, low and medium voltage class H (180 ° C) power cable application areas
Medium and low voltage class H (180 ° C) power cables are widely used in the following areas due to their high temperature resistance and high voltage transmission characteristics:
High-temperature industrial environments: such as steel, smelting, ceramics and other high-temperature production environments, the cable is required to be able to work stably at high temperatures.
Power transmission and distribution systems: used for medium and low voltage power transmission in urban distribution networks, nuclear power cables, wind farms cables, industrial power and power substations.
Special application scenarios: such as aerospace, military equipment and other areas that require high temperature tolerance and stable power transmission.
V. Medium and low voltage class H (180 ° C) power cable safety and quality standards
Medium and low voltage H class (180 ° C) power cables in the production and use of the process need to strictly comply with the relevant safety and quality standards, such as national standards, industry standards, and the International Electrotechnical Commission (IEC) and other standards developed. These standards are designed to ensure that the safety, electrical and mechanical properties of the cable meet the specified requirements.
