GW4 Series Outdoor AC Electrical Disconnector 12kV 40.5kV Single Pole Isolation witch

GW4-12(40.5)outdoor AC high voltage disconnect switch is used to open and close circuit with voltage but no-load 50/60Hz, 12(40.5)kV power system. It accords with standards of IEC129-1984 AC Disconnect Switch and Earthing Switch and GB1985 and other relative standards.

Structure feature
This disconnect switch consists of pedestal, insulating brace, electric material and operating mechanism. There are two braces on each pole, and electric blade is 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 degrees to close. We can connect three single-pole disconnect switches into a linkage three-pole switch through interlink rod. This disconnect switch can be matched with CS11 type or CS17 type manual mechanism, thereinto, CS17 be used in disconnect switch with earthing fitting. (motor mechanism can be installed according to user’s requirement), Reasonable structure, flexible operating; convenient installation, able to use single-pole or three-pole; wide distance of contact, safe and reliable insulating. The earthing type is flexible according to user’s requirement, single earthing dual earthing or without earthing can be chosen.
