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
