A2Z-DGIS Series Dry Air Gas Insulated Switchgear is designed for medium voltage applications where environmental responsibility, compact design, operational safety, and reliable power distribution are required.
Instead of SF6 gas, A2Z-DGIS Series uses climate-friendly dry air insulation. This structure helps eliminate the operational difficulties and environmental concerns associated with SF6 gas systems while maintaining the advantages of gas insulated switchgear technology.
All switching equipment is housed in a sealed stainless-steel tank in accordance with IEC 62271-200 requirements. The dry air insulation medium does not contain F-gases, is colorless, non-flammable, non-toxic, and does not contain chemically harmful components.
A2Z-DGIS Series offers a compact and modular structure suitable for medium voltage distribution networks, renewable energy plants, industrial facilities, transformer substations, transportation infrastructure, and utility applications.
The series provides high service continuity, internal arc safety, mechanical and electrical interlocking, ergonomic operation, and flexible system configurations according to project requirements.
