At the same time, due to the vast territory of our country, most of the areas are located in temperate and subtropical regions, which are very suitable for the reproduction of rats and ants. In addition, the ecological environment has been improved in recent years. Therefore, the activities of rats and ants are rampant. It has caused immeasurable losses to the society, so a new type of ultra-high voltage cable was developed to meet the needs of the society

The invention relates to an environment-friendly anti-mouse and anti-white ant 500KV ultra-high voltage cable. The cable comprises a conductor, wherein a semiconducting wrapping layer is wound on the conductor; a shielding layer, an insulating layer and an insulating shielding layer are in triple extrusion outside the semiconducting wrapping layer; and a water-blocking tape wrapping layer, an aluminum longitudinal covering embossing layer, a pitch anticorrosive layer, an outer protecting layer and a semiconducting coating are sequentially arranged outside the insulating shielding layer from interior to exterior. The cable is reasonable in structure, novel in material and advanced in process; due to the adoption of an ultra-clean insulating material with high dielectric property and an ultra-clean and especially smooth semiconductor shielding material with a special additive, the field breakdown strength of the cable is improved; an environment-friendly polymer is adopted in a sheath layer, so that the cable can drive away mice and ants for a long time; and the cable is flame resistant, heat resistant, environment-friendly and long in service life, is the preference of the ultra-high voltage cable and is worth being widely popularized.
Description
technical field [0001] The invention relates to an ultra-high voltage cable, in particular to an environment-friendly rat-proof and termite-proof 500KV ultra-high voltage cable. Background technique [0002] In recent years, the domestic demand for 220KV and 500KV ultra-high voltage XLPE cables has increased year by year, especially in the development of hydropower resources in the western development. Most hydropower stations and pumped storage stations require a large number of EHV XLPE cables. At the same time, due to the vast territory of our country, most of the areas are located in temperate and subtropical regions, which are very suitable for the reproduction of rats and ants. In addition, the ecological environment has been improved in recent years. Therefore, the activities of rats and ants are rampant. It has caused immeasurable losses to the society, so a new type of ultra-high voltage cable is developed to meet the needs of the society. Contents of the inventio...
