CKSS-12 Solid Insulated 22kv Electric Panel
CKSS-12 SOLID SWITCHGEAR.The vacuum arc extinguishing chamber and its conductive connection, disconnector, grounding switch, main bus, branch bus and other main electrical circuits are single or combined and then encapsulated with solid insulating medium into one or several modules with full insulation and full sealing performance that have certain functions and can be combined or expanded again. The module surface accessible to people is coated with conductive or semi conductive shielding layer and can be directly and reliably grounded.
