IEC air-insulated switch disconnectors are suitable for cable sectionalizer, transformer, motor and capacitor bank switching, in secondary distribution substations for supplying lines, transformers and ring networks, can be combined with DIN standard fuses for transformer protection. ANSI version is used in metal-enclosed switchgear, pad mounted cabinets, mining and capacitor switching applications.
Gas-insulated switch disconnectors are based on sealed for life SF6 technology that offers high performance, reliability and long-life in a compact installation footprint. Recent addition to the range is the new GSec, designed to meet the specific requirements of the latest IEC standards.
Earthing switches come in two forms: independent earthing switches and combined earthing switches with integral current transformers. The current transformers of the combined version form the mounting base for the earthing switch contacts thus reducing the space required in the cubicle
- Simplicity, reliability and long life have been tested to withstand over 100 breaking operations at nominal current – many time more than competitive designs
- Full range of products enables the flexibility to pick the most suitable solution based on preferred schemes
- Global installed base
