Overcoming the environmental compliance challenges faced by traditional SF6 equipment
Are you worried that the existing SF6 gas-filled cabinets will need to be rectified or fined due to the tightening of environmental policies? The greenhouse effect of SF6 gas is 23,500 times that of carbon dioxide, and its emission control has become a top priority in the power industry. Continuing to use traditional equipment not only incurs high carbon emission costs but also may be eliminated from the market due to not meeting green assessment standards.
The GIS Eco-friendly Gas Cabinet of Junray Electrical is specifically designed to address this industry issue. We have abandoned the highly polluting pure SF6 gas and instead use harmless dry air or mixed environmentally friendly gases. This means that your power distribution projects will no longer produce any greenhouse gases, completely eliminating the worries about environmental compliance and helping you take the initiative in green infrastructure and environmental assessment.
Environmental protection determines the future.
The core competitiveness of GIS Eco-friendly Gas Cabinet lies in its medium substitution solutions and structural design:
Zero greenhouse effect: By using environmentally friendly dry air or mixed gases, it fundamentally eliminates greenhouse gas emissions, perfectly meeting international and domestic environmental protection standards, helping you easily pass environmental protection inspections.
Fully sealed and highly protective: Inheriting the excellent traditions of GIS equipment, the gas cabinet adopts a fully sealed welding structure with extremely high protection level. Whether it is salt spray in coastal areas, high humidity basements, or dusty industrial environments, it can effectively prevent external erosion and ensure that internal components are not affected.
Maintenance-free design: Thanks to the stability of the environmentally friendly gas and the fully sealed structure, the equipment requires almost no maintenance during its lifecycle. Compared to ordinary ring main units, it eliminates the hassle of frequent inspections and significantly reduces the operation and maintenance costs throughout the entire lifecycle, especially suitable for remote or inaccessible sites.
Adaptation to environmental protection requirements: Perfectly meeting current environmental protection requirements, it can be perfectly adapted for those cities and regions with high environmental protection requirements, without worrying about environmental assessment.
High reliability: With a low failure rate and more stable operation, it has a lower failure rate than SF6 gas-filled cabinets, and has higher reliability, perfectly adapting to scenarios with high reliability requirements.
As a professional Manufacturer with profound technical expertise, Junray Electrical strictly adheres to the national standards for GIS environmental-friendly gas cabinets in its production. Our factory is equipped with advanced laser welding and helium mass spectrometry leak detection equipment to ensure the ultimate sealing of each gas box.
This GIS Eco-friendly Gas Cabinet features a complete "five-proof" mechanical interlock function, effectively preventing misoperation and ensuring the safety of personnel and equipment. Each factory-delivered cabinet undergoes strict sealing tests, pressure tests, and interlock tests to ensure stable operation within the voltage range of 12kV to 40.5kV. We guarantee that the high reliability and fault rate control of our products are superior to or equivalent to traditional SF6 gas-filled cabinets, providing you with the most reliable power protection.

This project involves the construction of a new 10kV power distribution system for a mixed-use commercial and residential complex in a new urban district. The development comprises high-rise residential buildings, commercial blocks, underground parking facilities, and associated public utility power systems. Situated in a prime urban landscape zone with high population density, the project is subject to strict government environmental impact assessment (EIA) requirements mandating zero-fluorine, low-carbon, and eco-friendly operations with no leakage; the large-scale use of traditional SF6-insulated switchgear—which utilizes a potent greenhouse gas—is prohibited.
The site's power distribution rooms are characterized by limited space, high humidity, and poor ventilation, alongside stringent fire safety and environmental standards. Traditional open-type XGN switchgear and SF6-insulated units were deemed unsuitable due to issues such as non-compliance with environmental regulations, large footprints, leakage risks, and complex operation and maintenance (O&M) requirements. Consequently, the project utilizes eco-friendly 10kV GIS (Gas-Insulated Switchgear) units insulated with clean air, ensuring green power distribution, maintenance-free operation, and high safety and reliability.
Environmental Non-compliance: Traditional SF6 gas is a potent greenhouse gas; strict EIA regulations in the new urban district restrict its use, making it impossible to pass acceptance inspections.
Large Equipment Footprint: Conventional fixed-type high-voltage switchgear occupies significant space; the project's distribution rooms have limited space, making the installation of conventional units unfeasible.
Poor Environmental Adaptability: Underground distribution rooms are prone to dampness and condensation; standard switchgear cabinets are susceptible to surface tracking, corrosion, and insulation degradation.
High Leakage Risk: Traditional SF6 switchgear is prone to micro-leakage during long-term operation, requiring extensive annual leak detection efforts.
High O&M Costs: Requirements for periodic gas replenishment, leak detection, and testing result in complex and costly long-term maintenance.
The project’s 10kV high-voltage distribution system exclusively utilizes eco-friendly GIS units insulated with clean air (or dry air) instead of traditional SF6-insulated switchgear. This configuration meets the standards for green urban power grids, low-carbon construction, and environmental acceptance inspections. Key Equipment Specifications

The 10kV eco-friendly GIS switchgear is currently the mainstream alternative for new urban districts, underground distribution rooms, green buildings, and zero-carbon grid projects. Compared to traditional SF6 ring main units and fixed high-voltage switchgear, this solution offers outstanding advantages—such as being eco-friendly and pollution-free, having a compact footprint, and being moisture-resistant, maintenance-free, safe, and reliable—making it perfectly suited to the requirements of modern urban high-standard power distribution, environmental compliance, and long-term stable operation.
