GB/T 26166-2010Wall bushings for ±800kV DC power systems (English PDF)

Foreword

Appendix A of this standard is an informative annex. The standard proposed by China Electrical Equipment Industrial Association.

1 Scope

This standard specifies the ± 800kV DC system with wall bushing characteristics and test.

This standard applies to ± 800kV DC system with a wall bushing, wall bushing including bus lines, the midpoint of the bus wall bushing (per pole double valve And when there is a bypass switch), neutral bus wall bushing.
