Technical features :
It features compact,small volume and a longitudinal direct-acting driven arrangement to decrease the size of the switchgear effectively.
Both manual and motor driven charged operations are available and it is convenience to local or remote operation by the final user .
The key parts are subjected to the nitrogenation treatment and they are durable and have high impact strength.The component surface adopt composite zinc plating and the long-term low temperature grease is applied so that the product is able to meet different weather conditions.
Both AC and DC power operation are available and it is convenience for the users without DC power supply.
