application

Divide the switch

As a demarcation switch, it can be realized without the switch of the superior or the switch of the substation, quickly and automatically protect and isolate the internal faults of the users, reduce the power failure range, and ensure the power supply safety in non-fault areas.

Section switch

As a sectional switch, cooperate with the substation to identify the fault area and quickly isolate it, and reliably restore the power supply in the non-fault area.

Contact switch

As a contact switch, can achieve "hand in hand" ring network power supply, reducing the scope and time of power failure, improve power supply reliability.

Prepared from the investment protection switch

As a self-protection switch device, applied to the dual power into the line of a main and non-segmented operation of the power system and plant Kuang enterprises, when the normal power supply line failure or power supply itself when the accident and power outage, manual, automatic fast Switch to standby power to ensure the normal operation of the client, the economic loss of power outage to a minimum.
