摘要
中压交联聚乙烯电缆的水树老化是造成电缆电气性能和机械性能下降,运行寿命减少的主要原因,抗水树电缆的使用可以大幅度提高交联聚乙烯电缆的使用寿命,了解抗水树电缆的优势,掌握抗水树电缆的鉴定试验方法,可以促进我国抗水树电缆的发展。
Water tree aging of middle voltage XLPE cable is the main factor which causes decline of electric performances, mechanical properties and operating life. The use of TR-XLPE cable can greatly improve the service life of cables. Knowing the superiorities of TR-XLPE cables and understanding its qualification test is helpful for the development of TR-XLPE cables of our country.
