CWH-12 Environmentally Friendly Medium-Voltage Ring Main Unit

Dimensions: 420×900×2000 Overview: The CWH‑12 is a next‑generation, SF6‑free, environmentally friendly gas‑insulated switchgear independently developed by Chengwei Electric. Its live parts are fully enclosed within a welded cabinet made of 304 stainless steel, using dry air as the insulating medium. By eliminating traditional SF6 greenhouse gases, it achieves true green, low‑carbon operation, thereby reducing greenhouse gas emissions and aligning with the grid's dual‑carbon goals. It is ideally suited for urban grid upgrades and new distribution projects that demand stringent environmental standards.

CWC12 SF6 Metal-Enclosed Ring Main Unit

Dimensions: 420×800×2100 Overview: The CWC‑12 series SF6 gas‑insulated, fully enclosed compact ring main unit (RMU) is a next‑generation, 12 kV modular metal‑enclosed switchgear independently developed by Chengwei Electric. All primary energized components are sealed within a welded 304 stainless steel enclosure, forming a fully closed system. This design delivers exceptional full‑seal and full‑insulation performance, effectively isolating the equipment from external environmental factors such as moisture, dust, salt spray, condensation, and flooding, thereby ensuring reliable operation of the power system.

RM AirSeT Eco-friendly Gas-Insulated Switchgear

Dimensions: 420×850×2000 Overview: The RM AirSeT eco‑friendly gas‑insulated switchgear is a flagship product prominently promoted by Chengwei Electric as an authorized Schneider partner. Compliant with both GB and IEC standards, it uses dry air as the insulating medium, eliminating SF6—a greenhouse gas—and features a fully sealed, fully insulated cabinet design. Throughout its entire lifecycle, no gas replenishment is required, fundamentally mitigating the risk of gas leakage, reducing operation and maintenance costs, and minimizing environmental impact. It is the preferred choice for next‑generation smart grid applications in green power distribution.
