150℃ XLPO (cross-linked polyolefin) wire and cable material is a high-performance material designed for new energy vehicles. It improves the heat resistance, mechanical properties and chemical stability of the material through the radiation cross-linking process. This material is often used to manufacture high-voltage cables inside new energy vehicles, which need to maintain stable performance in high temperature, high pressure and harsh chemical environments.
Heat resistance: XLPO material can withstand continuous operating temperatures up to 150℃, suitable for the connection of high-temperature components such as new energy vehicle batteries, motors and control systems.
Irradiation cross-linking: Through the radiation cross-linking process, a stable three-dimensional network structure is formed between the molecular chains of XLPO material, which improves the heat resistance and mechanical strength of the material.
Halogen-free flame retardant: XLPO material is usually halogen-free, and produces less toxic gases and corrosive smoke when burning, which meets the requirements of new energy vehicles for environmental protection and safety performance.
Excellent electrical insulation performance: XLPO provides good electrical insulation performance, ensuring the safety and reliability of cables when transmitting electrical energy.
Chemical resistance: XLPO has good resistance to a variety of chemicals such as acids, alkalis and oils, and is suitable for use in new energy vehicle components with complex chemical environments.
Softness and ease of installation: XLPO materials maintain a certain degree of softness, which is convenient for cable installation and wiring, especially when the interior space of the vehicle is limited.
Environmental characteristics: XLPO materials comply with environmental protection requirements such as ROHS, do not contain harmful substances, and are environmentally friendly materials.
Aging resistance and durability: XLPO materials have good aging resistance, can maintain stable performance during long-term use, and extend the service life of the cable.
Processing performance: XLPO materials can be processed into cables through extrusion molding, with high production efficiency and suitable for large-scale production.
Application areas: XLPO insulation materials are widely used in high-voltage wires in new energy vehicles, including connecting wires for key components such as battery packs, motors, and controllers.
This material was developed to meet the high-performance requirements of new energy vehicles for cable materials, especially in terms of high temperature, high pressure and high safety. With the continuous development of new energy vehicle technology, the application of 150℃ XLPO irradiation cross-linked halogen-free flame-retardant polyolefin wire and cable materials will also be further expanded.
