Апстракт
This standard applies to cast resin partitions pressurized with inert gases, for example sulfur hexafluoride or a mixture of gases such as sulfur hexafluoride and nitrogen used in indoor or outdoor installations of high-voltage switchgear and controlgear, where the gas is used principally for its dielectric and/or arc-quenching properties, with rated coltages - 1kV and up to and including 52 kV and with gas-filled compartments with design pressure greater than 3 bar (gauge); and with rated voltage 72,5 kV and above. The partitions comprise pressurized barriers in electrical equipment not necessarily limited to the following examples: circuit breakers, switch disconnectors, earthing switches, current transformers, voltage transformers, surge arrestors, busbars and connections, cable connections. This standard does not apply to high-voltage bushings (see HD 358 83 (IEC 517)
