Disconnect Switch

GWHY1-27.5 outdoor disconnect switch is used to close and open 27.5kV 50/60Hz line system under with voltage and no load condition it accords with standards of IEC62271-103: High voltage switches.

1. Disconnect switch consists of frame, operating insulating, static contact and operating mechanism.
2. There are two braces on each pole, electric blade installed on the top of each brace and the connection point of the two blades
is between the two braces. With the driving of operating mechanism, the two blades can rotate horizontally ninety degree to close.
3. Long term mechanical life.
4. Soft copper conductor connect with electric plate and connection frame separately, this structure will reduce the connection resistance.
5. Tinned soft copper take current can reduce the temperature rising, main contact finger with stainless steel spring, this can make sure steady circulation and avoid spring rust and failure occurring.
6. Disconnect switch is single phase, three single-pole disconnect switches into a linkage three pole switch through interlink rod.
It can be matched with CS17 type manual mechanism or motor mechanism.
7. Reasonable structure, flexible operating, convenient installation, able to use by single pole or three pole, wide distance of contact, safe and reliable insulating.
