| Model NO. | CYD-4 Hydraulic Disc Spring Operating Mechanism |
| Rated voltage | 220kV |
| Series | CYD-4 |
The CYD-4 series hydraulic disc spring operating mechanism uses disc springs as energy storage components. Disc springs have excellent force characteristics, are not affected by environmental temperature, store a large amount of energy, and have smooth force characteristics. Its structure adopts an integrated module design without pipeline connections. Adopting advanced sealing structure design, advanced dynamic and static sealing systems, internal integrated hydraulic buffer system, high system pressure, compact structure, high operating power, stable and reliable performance. Mainly suitable for high voltage and high current applications in GIS dead and tank circuit breakers with voltage levels of 252kV-1000KV.
