《GB/T 22078.1-2008额定电压500kV(Um=550kV)交联聚乙烯绝缘电力电缆及其附件 第1部分: 额定电压500kV(Um=550kV)交联聚乙烯绝缘电力电缆及其附件 试验方法和要求》由TC213(全国电线电缆标准化技术委员会)归口,主管部门为中国电器工业协会。
GB/T 20078《额定电压500kV(Um =550kV)交联聚乙烯绝缘电力电缆及其附件》分为三个部分,本部分为GB/T 20078 的第1部分。
GB/T 20078的本部分规定了额定电压500kV(Um =550kV)固定安装的交联聚乙烯绝缘电缆系统、电缆及其附件的试验方法和要求。
此试验要求适用于通常安装和运行条件下的单芯电缆及其附件,而不适用于特种电缆及其附件,诸如海底电缆。对特种电缆可能需要修改本部分的试验或可能需要设计特殊的试验条件。
本部分不包含交联聚乙烯绝缘电缆和纸绝缘电缆的过渡接头。
本部分修改采用IEC 62067:2006 Ed.1.1《额定电压150kV(Um =170kV)以上至500kV(Um=550kV)挤包绝缘电缆及其附件―――试验方法和要求》(英文版)。IEC 第20技术委员会(电缆)已决定此出版物的内容直至2010年保持不变。至该时,此出版物将重新确认或废止或修订或修改。
本部分主要技术内容和编写格式、文本结构与IEC 62067:2006相同,但外护套材料仅采用与正常运行条件电缆导体最高温度90℃相适配的ST2 和ST7外护套混合料;型式试验中增加绝缘层微孔、杂质和半导电屏蔽层与绝缘层界面微孔、突起试验,相应增加附录E:绝缘层杂质、微孔和半导电屏蔽与绝缘层界面微孔、突起试验;增加外护套刮磨试验和铝套腐蚀扩展试验。绝缘偏心度要求和绝缘tanδ 值要求以及例行试验中局部放电试验灵敏度要求均严于IEC 62067:2006。有关技术性差异已编入正文中并在它们所涉及的条款的页边空白处用垂直单线标识。在附录F中给出了这些技术性差异及其原因的一览表以供参考。
Scope
This part of GB/T 22078 specifies the test methods and requirements for XLPE insulated cable systems, cables and their accessories for fixed installation with a rated voltage of 500kV (Um=550kV). This test requirement applies to single-core cables and their accessories under normal installation and operating conditions, but not to special cables and their accessories, such as submarine cables. For special cables it may be necessary to modify the tests of this standard or it may be necessary to refer to special test conditions. This section does not include transition joints for XLPE insulated power cables and paper insulated cables.
