AIR INSULATED CELLS with air insulation at atmospheric pressure
MODULAR SOLUTION
The cells are designed for use in secondary distribution, ensuring the power supply to domestic and industrial consumers.
These are modular, metal-enclosed cells with a simple busbar system and air insulation. They are designed to meet the requirements of most energy distributors and offer an efficient solution for extending existing SF₆ switchboards.
Functions
- Load break switch: Made of epoxy resin, which uses dry air for insulation and vacuum interrupters for switching.
- Insulation: Air-based, a safe and environmentally friendly medium.
- Structure: Modular, with fixed apparatus, allowing for rapid integration.
- Compatibility: Can extend or complement existing SF₆ switchboards.
