The outdoor high voltage AC isolation switch is used for opening and closing high voltage lines without load, electrically isolation high voltage lines from equipment under maintenance (such as high voltage busbars, circuit breakers), and can also be used for switching small capacitive or inductive currents.

Main Specifications:

- Rated voltage: 35-145kV

- Rated current: up to 1600A

- Peak withstand current: up to 80kA

- Short circuit withstand current/4s: up to 31.5kA

Features:

- Uses rolling bearing transmission, allowing for smooth and flexible operation.

- Transmission is achieved through a bevel gear mechanism, ensuring synchronized opening and closing actions of the poles.

- Equipped with a limit device to ensure the contact is in the optimal position. After operation, the handle is locked by a ring to prevent accidental operation, ensuring the reliability of the open and closed positions.

- Large contact opening distance provides sufficient insulation space to ensure safety.

- Three grounding methods are available. Reliable mechanical interlocking between the main shaft and the ground ensures safety. The user is allowed to select the grounding method as needed.

- The operating mechanism can be installed below any pole, providing the same operating effect for user convenience.
