CYD-4.6 Hydraulic Disc Spring Operating Mechanism(Extended Type)

1.The mechanism uses disc spring as energy storage medium and hydraulic oil as transmission medium, which makes it easy to obtain high pressure and make its structure small and compact.

2.Fast action, sensitive response, large output power, free of operation and maintenance, low operating noise, high reliability, good matching of output characteristics and circuit breaker load characteristics.

3.Integrated piping design

4.Six modules

5.Complex structure, manufacturing process, materials, processing precision requirements are particularly high

Application Scenarios

Installation place: indoor, outdoor organization box.

Ambient air temperature: upper limit +60℃, lower limit -30℃. If it is lower than -30℃, it should be specified in the order.

Altitude: ≤3000m.

Wind pressure not exceeding 700Pa (equivalent to wind speed 34m/s).

Relative humidity: the average daily relative humidity is not greater than 95%, the average monthly relative humidity is not greater than 90% (indoor); Salt spray, high humidity and heat areas should be considered in the design of the agency box condensation and precipitation effects.
