Overview of CT20A Spring Operating Mechanism

1. Product model and name
CT20A Spring Operating Mechanism
2. Main purpose and performance of the product
This machine is used to operate 126KV high-voltage SF6 porcelain column circuit breakers and enclosed GIS composite electrical appliances. The mechanism has two modes of energy storage: electric energy storage and manual energy storage. The opening and closing operations can be remotely and locally operated by electric or manual means.
3. Our institution can perform slow opening and closing operations with the help of specialized tools.
Environmental conditions for use
1. Environmental temperature: -30 ℃ to+40 ℃
2. Relative temperature: daily average not exceeding 95%; The monthly average is not greater than 90%.
3. Places without frequent and severe vibrations.
4. Usage location: indoor or outdoor
5. Protection level IP4XW
