Features and construction
Each metal-enclosed panel integrates a measurement and control section at the top, an SF6-insulated switching/busbar section in the middle, and a cable/protection compartment at the bottom, with clear mimic diagrams and status indicators on the front. The sealed SF6 chamber keeps insulation stable regardless of ambient humidity, while the coated-steel enclosure resists corrosion for a long, safe service life.
Typical applications
Medium-voltage distribution for utilities, substations, industrial plants, commercial buildings, renewable-energy plants and infrastructure projects requiring compact, reliable ring-main switching.
Customisation options
Voltage, rated current, panel configuration, protection level, color and busbar arrangement are customizable to project single-line requirements.
