Airing 12kV Series Dry Air Insulated Ring Main Unit

Description

The Airing 12kV series dry air insulated ring main unit uses environmentally friendly gas as the insulation medium. It coexists harmoniously with nature, fulfilling the social responsibility of a modern manufacturing enterprise dedicated to ecological civilization.

The core unit of the series integrates a patented self-energy load switch (combining pressure-blown and gas-generating arc extinction) and an ultra-low resistance vacuum circuit breaker. Primary live components are enclosed in a micro-positive pressure stainless steel gas tank filled with environmentally friendly gas, isolated from the external environment. This ensures that the switchgear and all primary live parts inside the tank are not affected by external environmental changes, realizing maintenance-free operation, improving power supply reliability, enhancing personnel safety, and meeting the needs of economical and stable operation.

The Airing 12kV series is widely applied in urban distribution networks, smart microgrids, commercial real estate, municipal engineering, industrial parks, residential districts and other fields. It practices environmental protection concepts and continuously creates value for customers.
