Introduction to the standard requirements for vehicle cable materials

Description: With the rapid development of the new energy industry, new energy cables, as key components of power transmission, have increasingly stringent standard requirements for insulation materials. The following is a detailed analysis of the standard requirements for new energy cable insulation materials:

1. Physical performance requirements: The physical properties of new energy cable insulation materials must comply with national standards,

Mainly include:
Tensile strength: Ensure that the cable is not easy to break when stretched by external force, and ensure the stability and safety of the cable.
Elongation at break: Reflects the elongation ability of the material before breaking, and is an important indicator for evaluating the flexibility of the material.
Hardness: Appropriate hardness can not only ensure the insulation performance of the cable, but also avoid excessive wear during installation and use.

2. Electrical performance requirements: Electrical performance is the core requirement of new energy cable insulation materials, mainly including: Dielectric strength: Indicates the ability of the material to withstand the action of the electric field without being broken down, and is a key indicator for evaluating the insulation performance of the cable.

3. Heat resistance requirements: New energy cables may be subjected to higher temperatures during operation, so the heat resistance of the insulation material is crucial. Mainly include:

Long-term use temperature: refers to the highest temperature that the cable can continuously withstand under normal working conditions. The insulation materials of new energy cables are usually required to have a higher long-term use temperature to meet the needs of different application scenarios.

IV. Environmental aging resistance requirements: New energy cables may face various harsh environmental conditions during use, such as ultraviolet rays, ozone, humidity and heat, so the environmental aging resistance of insulation materials is also an important consideration. Mainly including:

Light aging resistance: refers to the ability of materials to resist aging under light conditions, ensuring that the cables can maintain stable insulation performance for a long time when used outdoors.

Heat aging resistance: Under high temperature conditions, materials may undergo thermal decomposition, oxidation and other reactions, resulting in performance degradation, so they need to have good heat aging resistance.
Moisture and heat aging resistance: In a humid and hot environment, materials may absorb moisture and cause performance changes, so they need to have good moisture and heat aging resistance.
In summary, the standard requirements for new energy cable insulation materials cover physical properties, electrical properties, heat resistance, environmental aging resistance and other aspects to ensure that the cables can maintain stable insulation performance and good operating conditions in various application scenarios.
