Eco Gas Insulated Ring Main Unit

The Eco Gas Insulated Ring Main Unit is an environmentally friendly power distribution product. All high-voltage live parts are sealed inside a stainless steel tank. The unit uses dry air as the insulation medium. This design eliminates the environmental risks of traditional SF6 gas. The unit runs reliably and safely for operators.

We are ChangZhou HY Power Electric Co., Ltd. We started production on March 18, 2024. We follow green manufacturing principles. Throughout the product's life cycle, from design to disposal, we minimize environmental impact. We use recyclable thermoplastic materials. We avoid non-degradable thermosetting materials. Our commitment to sustainability makes this eco-friendly unit a responsible choice for modern power projects.

The stainless steel tank holds dry air at 0.02 MPa. The protection level is IP67. The tank uses laser cutting and laser welding. Non-welded sealing surfaces use O-ring seals. You can install this Eco Gas Insulated Ring Main Unit in damp, sandy, dusty, or salty areas. You do not need extra protection or cleaning. The expansion busbar is fully shielded. It stays unaffected by outside conditions and needs no maintenance. All live parts stay inside the sealed chamber. The tank is securely grounded. Operators cannot touch high-voltage parts. The insulation status is monitored in real time. You can adjust parameters on site. The switch has a reliable arc relief channel. It passed the internal arc test at 20kA for 1 second. The cable compartment door and switch status have a mechanical interlock. This adds another layer of safety for operators.

All standard module units are only 410mm wide, except for busbar coupling and metering cabinets. The cable connection bushings are at the same height across all units. This makes installation easier for on-site teams. The disconnector and earthing switch are combined into a three-position switch. They share one moving contact. The operating mechanism sits in the middle of the unit. You can operate it manually or electrically. The gas chamber has external cone cable connection bushings. You can plug multiple cables in parallel. You can also connect surge arresters.

We check every production step carefully. All purchased parts go through our quality inspection department. Workers do self-inspections during production. Quality inspectors do spot checks. Before shipping, we inspect each unit completely. We check the appearance, wiring, and do a power-on test. We accept third-party inspections. Every Eco Gas Insulated Ring Main Unit leaves our factory in perfect condition.

We support OEM and ODM services. The minimum order quantity is 2 units. Standard products ship in 25 working days. Before the sale, we design solutions based on your project needs and local power standards. During production, we follow a strict schedule. After the sale, we provide video guidance. We respond to all feedback within 12 hours. We offer a one-year warranty. Our export packaging has three protective layers to keep your equipment safe during shipping.
