Publish Time: 2024-10-29
Cross-linked Polyethylene (XLPE) is a polyethylene material that is irradiated by a high-energy electron beam generated by an electron accelerator. This treatment method forms a three-dimensional network structure between polyethylene molecular chains. Cross-Linked Irradiated PE Line has shown excellent performance in power transmission and is widely used in high-voltage cables and other fields.1. Superior electrical propertiesHigh insulation strength: Cross-linking treatment significantly improves the electrical insulation properties of polyethylene, and its dielectric strength and electrical breakdown resistance are significantly higher than untreated polyethylene. This enables cross-linked irradiated PE cables to withstand higher voltages and are suitable for high-voltage power transmission.Low dielectric loss: Dielectric loss directly affects the efficiency of power transmission. The low dielectric loss tangent of Cross-Linked Irradiated PE Line makes it show lower energy loss under AC electric fields, ensuring the high efficiency of power transmission.2. Excellent mechanical propertiesHigh strength and wear resistance: Cross-linked irradiation treatment enhances the degree of cross-linking between polyethylene molecules, improves the mechanical strength, wear resistance and tear resistance of the material, makes the cable less susceptible to damage under external pressure or physical damage, and prolongs its service life.Flexibility: Cross-Linked Irradiated PE Line maintains good flexibility while improving mechanical strength, which is convenient for installation and wiring, and reduces the difficulty and cost of installation and construction.3. Heat resistance and aging resistanceExcellent high temperature resistance: Compared with non-cross-linked polyethylene, Cross-Linked Irradiated PE Line maintains better stability in high temperature environments and can work for a long time under high temperature conditions without decomposition or performance degradation. This feature enables it to cope with high temperature environments such as those inside power stations during power transmission.Aging resistance: Cross-linking treatment improves the oxidation resistance and UV resistance of polyethylene, reduces the aging rate of the material under long-term outdoor exposure, and prolongs the service life of the cable.4. Thermal stability and flame retardancyThermal stability: Cross-Linked Irradiated PE Line exhibits good thermal stability in high temperature environments, is not prone to thermal deformation or melting, maintains structural integrity, and ensures the continuity of power transmission.Self-extinguishing properties: Some cross-linked irradiated PE materials have good flame retardant properties. Once the fire source is removed, they can self-extinguish, reducing the risk of fire and improving the safety of power transmission.5. Resistance to environmental stress crackingResistance to stress cracking: In actual power transmission, cables may be affected by various environmental stresses (such as mechanical stress, thermal stress, etc.). Cross-Linked Irradiated PE Line can resist cracking and deterioration caused by these stresses.6. Environmental protection and sustainabilityLow toxicity and environmental protection: Cross-Linked Irradiated PE Line does not emit harmful substances during production and use, and is easy to recycle after disposal. This meets the requirements of modern environmental protection and sustainable development.7. Wide application and market acceptanceGood application performance: At present, cross-linked irradiated PE cables have been widely used in high-voltage power transmission and distribution networks around the world, and their good performance and long-term stable performance have won wide recognition in the market.Technology maturity and standard establishment: With the development of material science and processing technology, the production process and technology of cross-linked irradiated PE have become very mature, and relevant international and industry standards have also been established, providing technical and regulatory guarantees for large-scale applications.Cross-Linked Irradiated PE Line has become a high-performance material for power transmission with its superior electrical insulation performance, mechanical properties, heat resistance, aging resistance, thermal stability and flame retardancy, environmental stress cracking resistance and good environmental performance. Its wide application in high-voltage cables and power systems has proved its excellent performance in ensuring power transmission efficiency, safety and stability.
