Frequently Asked Questions
What medium-voltage components does TOONICE provide?
TOONICE provides indoor medium-voltage vacuum circuit breakers, SF₆ load break switches and switchgear trucks, including voltage transformer trucks, isolation trucks and metering trucks, for medium-voltage switchgear and distribution applications.
What is the difference between vacuum circuit breakers, SF₆ load break switches and switchgear trucks?
Vacuum circuit breakers are used for switching and protection, including the interruption of short-circuit currents. SF₆ load break switches are used for load switching, isolation and earthing, and can be combined with fuses for transformer and feeder protection. Switchgear trucks are withdrawable functional units for voltage measurement, isolation and metering in withdrawable switchgear.
What voltage levels are available for TOONICE medium voltage components?
TOONICE medium voltage components are available for applications up to 40.5 kV. The available voltage classes depend on the product series and configuration.
Can TOONICE provide project-specific component configurations?
Yes. Ratings, interfaces and configurations can be selected according to system voltage, rated current, switchgear design, installation arrangement and project requirements.
