The GW54 disconnectors are available up to 550 kV, 5000 A and 63 kA. The four solid pantograph arms have a large open/ close range to provide reliable on-position connection. The contacting area between fixed and moving contacts is designed to provide excellent electrical conductibility. The parallel connection lowers circuit resistance. Some other noteworthy features of the GW54 disconnector are:
- Minimized contact resistance
- All joints connected through rotating contacts having incomparable performance on reliability, sealing, conductivity and anti-corrosion
- Transmission parts insulated from conducting parts by nylon tubes
- Mechanism housed in an aluminum enclosure protecting against ice and pollution
- Interlocking for reliability under extreme conditions
- Ice breaking capacity
