Product descriptions from the supplier
The main hydraulic components of the CYD-8 series hydraulic disc spring actuator include combination disc springs, working cylinders, control valves, oil pump motors, energy storage cylinders, stroke switches, safety valves, high-pressure relief valves, low-pressure oil tanks, connecting seats, and other components; Using disc springs as energy storage components, disc springs have excellent force characteristics, are not affected by environmental temperature, store large amounts 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, and internal integrated hydraulic buffering system, the system has high pressure, compact structure, high operating power, stable and reliable performance. Mainly suitable for high voltage and high current GIS and tank circuit breakers with voltage levels of 252kV-1000KV.
