The application of radiation cross-linking technology in charging pile cable materials provides a material solution with excellent performance.
Improved temperature resistance: Through radiation cross-linking, the temperature resistance of cable materials is significantly improved, and it can adapt to the high temperature environment generated by charging piles during operation.
Enhanced mechanical strength: The radiation cross-linking process forms a mesh structure, which enhances the mechanical strength of the material, including tensile strength and tear resistance, making the cable more durable when subjected to physical stress.
Excellent electrical insulation performance: Radiation cross-linked materials provide better electrical insulation performance, ensuring the safety of cables when transmitting high currents.
Low smoke halogen-free flame retardant properties: Radiation cross-linked cable materials usually contain halogen-free flame retardants, which makes the cables produce less smoke and toxic gases when encountering fire, improving the safety of charging piles.
Chemical corrosion resistance: Radiation cross-linked materials have good tolerance to oils and a variety of chemicals, and are suitable for use in various environmental conditions.
Weather resistance: Radiation cross-linked cable materials can resist the influence of ultraviolet rays and severe weather conditions, and are suitable for long-term outdoor exposure.
Softness and ease of installation: The radiation cross-linked material maintains a certain degree of softness, which is convenient for the installation and wiring of the cable.
Environmental characteristics: The radiation cross-linked cable material does not contain halogen, meets environmental protection requirements, and is an environmentally friendly material.
Aging resistance：The radiation cross-linked material has good aging resistance and can maintain stable performance during long-term use.
These characteristics make the radiation cross-linked cable material an ideal choice for new energy vehicle charging pile cables, especially in new energy vehicle charging facilities that require high performance, high reliability and environmental protection. With the rapid development of the new energy vehicle industry, the application of radiation cross-linked cable materials will also be further expanded.
