Environmentally friendly gas-insulated metal-enclosed switchgear

A solution featuring natural, environmentally friendly gas insulation and vacuum interruption, offering a superior combination of high overall performance while eliminating temperature‑rise‑related gas emissions and the need for gas recovery and disposal throughout the equipment's entire lifecycle. Completely maintenance‑free, with a hermetically sealed primary circuit, its high‑voltage components are unaffected by altitude, ensuring robust environmental adaptability. The cabinet is compact: in a typical 12 kV configuration, the enclosure depth does not exceed 500 mm, minimizing space requirements. It is well suited for power grids, large industrial facilities, rail transit systems, commercial buildings, and other applications.

SF6 Gas-Insulated Metal-Enclosed Switchgear

The RGF‑40.5 series gas‑insulated switchgear is a next‑generation intelligent high‑voltage switching device developed by our company's R&D team, taking into account the inherent characteristics of power grids both domestically and internationally. All primary circuit components are housed within a stainless‑steel gas chamber filled with SF₆ gas, offering notable advantages such as a compact footprint that saves space, a high degree of integration that eliminates the need for maintenance, and simplified parts that ensure stable quality. This product is widely deployed in transmission, distribution, and substation applications under a variety of complex operating conditions.

SF6 Gas-Insulated Metal-Enclosed Switchgear

The RGF‑40.5 series gas-insulated switchgear is designed and manufactured in accordance with GB and IEC standards, featuring a fully sealed structure. It is suitable for harsh environments such as those characterized by pollution, salt spray, high humidity, and high altitudes, and offers multiple configurations to meet even more demanding requirements. It is applied in various settings, including 40.5 kV‑rated offshore and onshore wind‑farm step-up substations, offshore and onshore photovoltaic power‑generation step-up substations, energy‑storage step-up stations, distribution‑substation step-down stations, urban subways, chemical plants, and small secondary distribution substations, delivering safe, reliable performance with excellent resistance to contamination and moisture.
