1 Scope

1.1 Scope This standard specifies the rated voltage 72.5kV and above, rated frequency of 50Hz gas insulated metal-enclosed switchgear and recharge Body and crowded insulated power cable connection of the filling fluid and dry cable terminal rating, design and structure, standard size, test and supply side Boundaries and other requirements. This standard applies to the rated voltage 72.5kV and above, rated frequency of 50Hz gas-insulated metal-enclosed switch equipment recharge Body and crowded cable connection device, in a single-phase or three-phase arrangement of the cable terminal for the filling or dry. In the cable insulation and switching equipment The insulation of the gas is separated by an insulating cone. This standard is intended to establish the electrical and mechanical interchangeability of cable terminals and gas-insulated metal-enclosed switchgear connections and to determine Should be the boundary. In order to facilitate the use of this standard, the term "switchgear" is used to describe "gas insulated metal-enclosed switchgear".
