Learn about high voltage cable insulation

High-voltage cables are an important part in electric vehicles for transmitting high-voltage electrical energy. And the insulation layer, as a key part of the high voltage cable, plays the role of isolating and protecting the conductor. In this paper, we will introduce the types, functions and importance of high voltage cable insulation.

1. Types of insulation: The insulation of high-voltage cables can be made of a variety of materials, and common insulating materials include:

Rubber: Rubber insulation has good flexibility and heat resistance, suitable for general high-voltage cables.

Cross-linked polyethylene (XLPE): It is made of polyethylene materials with a temperature resistance rating of 75 ℃ after the change, and the temperature resistance rating can be as high as 150 ° C. XLPE insulation has excellent electrical properties and heat resistance, and is widely used in the field of high-voltage cables.

Cross-linked polyolefin (XLPO): XLPO insulation is a new type of insulation material with high heat resistance and chemical resistance. Compared with ordinary polyolefin, cross-linked polyolefin has better stretching, oil resistance, cold resistance, anti-cracking and other properties than ordinary polyolefin after irradiation cross-linking, which can satisfy the use conditions in harsh environments.

2. Functions of insulation layer

Isolation of conductors: the insulation layer can effectively isolate the conductors, prevent current leakage and short-circuit phenomenon, to ensure the safe transmission of electricity.

Protecting the conductor: the insulation layer can protect the conductor from the influence of the external environment, such as moisture, dust and chemical erosion, prolonging the service life of high-voltage cables.

Provide electrical performance: the insulation layer has good electrical insulation performance, which can prevent current leakage and interference and ensure the stable transmission of high-voltage electrical energy.

3. Importance of insulation

The quality and performance of the insulation layer of high voltage cables directly affects the safety and reliability of electric vehicles. A good quality insulation layer can effectively isolate the current and prevent safety accidents such as electric shock and fire. At the same time, a good insulation layer can provide stable electrical performance, reduce energy loss and interference during power transmission, and improve the efficiency and performance of electric vehicles.

To summarize, the high-voltage cable insulation plays a crucial role in electric vehicles. It not only isolates and protects the conductors to ensure the safe transmission of electrical energy, but also provides stable electrical performance to improve the efficiency and reliability of electric vehicles.OMG', as a company specializing in the research and development of high-quality cables for electric vehicles, designs and manufactures high-voltage cables by selecting appropriate, RoHS 2.0 & REACH-compliant XLPE/XLPO insulating materials to ensure the reliability of the high-voltage cable insulation.
