| 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, replacing traditional nitrogen energy storage cylinders. Disc springs have excellent force characteristics and are not affected by environmental temperature. The stored energy is large and the force characteristics are smooth.
Mainly used in high voltage and high current situations with a voltage level of 252kV, it is mainly used for the opening and closing operations of GIS circuit breaker switches and SF6 magnetic pole circuit breaker switches.
