介绍西门子公司研制500kV交联聚乙烯(XLPE)电缆及其附件的情况。详细描述500kV XLPE电缆的结构特征,材料特性,制造工艺及测试结果。
After intensive development tests including type tests in accordance with IEC 840, Siemens eventually completed the prequalification test recommended by Cigre for their XLPE cable systems up to 400kV. After successful conquest of the 400kV level, further improvements have been achieved to match the even higher demands in cables and accessories operated at 500kV service voltage.
