Frequently Asked Questions
What medium voltage switchgear products does TOONICE provide?
TOONICE provides metal-clad withdrawable medium-voltage switchgear and cubicle-type gas-insulated medium-voltage switchgear (C-GIS) for indoor primary distribution applications.
What voltage classes are available?
Medium-voltage switchgear is available up to 40.5 kV. KYN28 covers 12 / 17.5 / 24 kV, KYN61 is for the 40.5 kV class, and C-GIS is available in 12 / 24 / 36 / 40.5 kV classes according to product configuration and project requirements.
What is the difference between metal-clad withdrawable switchgear and C-GIS?
Metal-clad withdrawable switchgear uses a compartmentalized metal-clad structure with withdrawable vacuum circuit breakers, while C-GIS uses a compact metal-enclosed design with sealed SF₆ gas insulation and vacuum circuit breaker technology.
Can TOONICE provide project-specific medium voltage switchgear configurations?
Yes. Configurations can be engineered according to system voltage, rated current, short-circuit level, feeder arrangement, protection and control requirements, drawings and project specifications.
What technical documents are available for project review?
Available documents may include drawings, technical data sheets, routine test records, inspection reports and certificates according to project requirements.
