1. Description
CKSS Ⅱ solid insulated switchgear is a new kind of intelligent, environment-friendly switchgear with highly safety operation. It is applicable to secondary power distribution system in the voltage range up to 24KV.
2. Technical Feature
----Without SF6 gas, green & environment friendly
----Operating mechanism is at the front side and primary circuit is at the backside. Easily for operation, debug and test.
----Busbar is at the top side. Easily for assembly if extending more units at left/right side.
---- Incoming CB - DS/ES
---- Watch the DS physical open contacts from interior lighting in the cabinet
----Small size & flexible expansion
----Safe & reliable
----Spring operating mechanism with dual anti-misoperation system
----Fuse with sealed isolation
