GB/T 22383-2008 in English

《GB/T 22383-2008额定电压 72.5kV 及以上刚性气体绝缘输电线路》由TC65（全国高压开关设备标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准规定了交流额定电压72.5kV及以上、额定频率为50Hz的刚性气体绝缘输电线路的使用条件、额定值、设计和结构以及试验等方面的要求。本标准适用于交流额定电压72.5kV及以上、额定频率为50Hz的单极或三极气体绝缘金属封闭开关设备的电缆连接和挤包绝缘电缆连接。

Scope

This standard specifies the requirements for the service conditions, ratings, design and structure, and tests of rigid gas-insulated transmission lines (GIL) with an AC rated voltage of 72.5 kV and above and a rated frequency of 50 Hz. Realized by the non-corrosive insulating gas of air at atmospheric pressure. This standard is applicable to the application occasions of GB 7674-2008, and it can also be used in occasions not covered by the provisions of GB 7674-2008, for example: - occasions where all or part of rigid gas-insulated transmission lines are directly buried underground; or - rigid The installation site of the gas-insulated transmission line is wholly or partly an area accessible to the public; or - the place where the rigid gas-insulated transmission line is long (typically 500m in length and above). At each end of a rigid gas-insulated transmission line, dedicated components can be used to connect it to other equipment (such as bushings, power transformers, cable terminations, metal-enclosed surge arresters or GIS), which are covered by the respective technical standards. Unless otherwise specified, rigid gas-insulated transmission lines are designed for normal service conditions. This standard is used in conjunction with GB/T 11022-1999.
