10 1.1.6

• Newly developed switchgear for 72.5 -145 kV

• Based on many years of experience with GIS

• Single-phase enclosure• Vertical configuration of busbar

phases• Small gas compartments even in

busbars• Greater flexibility of plant layout

• Horizontal circuit breaker• Low closing and tripping energy

requirements• Spring operating mechanism

•Low static and dynamic forces•Modest building requirements

•Good accessibility•Easily removable busbar sections

•Convenient extension of existing stations

•Open secondary interface for most control systems

•Low operating costs•High availability
