Driven by global energy transformation and low-carbon upgrading, green switchgear has evolved from a new concept to a modern power engineering mainstream. It abandons traditional high-carbon SF6 insulation technology, adopts clean gas insulation and eco-friendly materials to achieve full life-cycle carbon reduction. This eco-efficient equipment has become an irreversible industry trend for power equipment iteration and upgrading.
The green switch cabinet is a new generation of medium and high voltage switch equipment that conforms to the international low-carbon environmental protection standard. Unlike traditional equipment that only focuses on electrical performance and operation safety, the green switch cabinet takes ecological protection and energy conservation as the core design index. The equipment adopts SF6-free clean insulating medium, vacuum arc extinguishing technology, high-efficiency low-loss conductive structure and material-saving modular design, covering the whole process of green production, low-carbon operation and environmental protection recycling.
As a typical ecological power equipment, its core value lies in the deep reduction of carbon emissions throughout its life cycle: zero greenhouse gas emissions during operation. Low energy consumption in the long-term power grid operation, low consumables in the production stage, and high recycling utilization after disposal, which solves the environmental protection shortcomings of traditional switch cabinets from the root, and comprehensively adapts to the global dual-carbon policy and the requirements of green power grid construction.
Traditional gas-insulated switchgear has long relied on SF6 gas, which has occupied the medium and high-voltage distribution market for many years due to its excellent insulation and arc extinguishing performance. However, with the upgrading of global environmental standards, its inherent defects have become increasingly prominent and have become the main bottleneck for the green transformation of the power industry. First of all, the greenhouse effect of SF6 gas is extremely strong, and a small amount of leakage can cause long-term atmospheric pollution that cannot be degraded. Secondly, the traditional cabinet has a large volume and consumes a lot of materials, with high consumption of steel and copper, and high carbon emissions in manufacturing and production. Third, traditional equipment requires regular gas detection, gas replenishment, and leakage detection and maintenance, with high maintenance costs and continuous indirect carbon emissions. Fourth, after the equipment is scrapped, the waste gas and waste are easy to cause secondary pollution, and the recovery utilization rate is extremely low.
At present, many countries around the world have introduced SF6 control policies to restrict the production and operation of fluorinated gas equipment, and traditional SF6 switch cabinets are gradually entering the phase of elimination, which is completely unable to adapt to the green and low-carbon industry trend of the future power industry.

The abandonment of SF6 greenhouse gas is the core technology mark of green switchgear. The environmental protection ring network cabinet series CLH-12/ 24 of Chuanli adopts high-purity nitrogen insulation technology, which is completely fluorine-free and pollution-free. Nitrogen is a natural component of the atmosphere, with a global warming potential of zero, and there is no environmental hazard after leakage. The equipment adopts a fully stainless steel sealed gas chamber structure, with a gas leakage rate of ≤0.01% per year, no need for annual gas replenishment, the insulation performance is stable over a long period of time, and realizes the reduction of carbon emissions from the source, completely solving the problem of greenhouse gas pollution in traditional switch cabinets.
Arc extinguishing technology is the core of the safe operation of high-voltage switchgear. The traditional equipment relies on SF6 gas to extinguish the arc, while the green switchgear adopts high-performance vacuum arc extinguishing technology, which realizes the rapid extinguishing of the arc in the vacuum arc extinguishing chamber, with stable breaking performance and strong overcurrent tolerance. The mechanical operation life of the CLH-12/ 24 vacuum circuit breaker unit can reach 10,000 times, and there is no gas consumption or pollution generation during operation, which takes into account both safety and environmental protection, and is the core technology of modern green ecological power equipment.
In response to the pain points of traditional cabinets being bulky and having a large amount of consumables, the green switch cabinet adopts a standardized modular design. The CLH-12/ 24 integrated load switch, vacuum circuit breaker, PT metering, busbar connection and other multifunctional units, the single module width is only 420mm; a single cabinet can integrate up to 4 functional modules, greatly saving the area of the distribution room. Compared with traditional equipment, the compact integrated structure reduces consumables by more than 20%, effectively reduces carbon emissions in manufacturing and production, and conforms to the trend of the green manufacturing industry.
The green switch cabinet realizes energy saving and carbon reduction throughout the operation cycle by optimizing the electrical structure. The CLH-12/ 24 adopts a high-conductivity copper conductor and an optimized design of electric field balance; the loop resistance is ≤150μ Ω, which greatly reduces the line loss and heat loss during long-term operation. Compared with traditional switchgear, the operating energy consumption is reduced by more than 15%, continuously reducing the carbon footprint of the power grid operation, and helping to achieve the dual carbon goals of the power system.

Global F-Gas regulations, low-carbon standards for power grids, and dual carbon control policies continue to tighten, clearly restricting the use and emissions of SF6 gas. National power grid projects, municipal projects, and new energy projects have included fluorine-free green equipment in their mandatory bidding standards, and green switchgear has fully replaced traditional SF6 equipment, becoming an irreversible global industry trend.
Modern ecological power equipment is no longer limited to the environmental protection of a single operation link, but realizes the low-carbonization of the whole process of raw material procurement, production and processing, installation and operation, and waste recycling. The green switch cabinet adopts recyclable environmental protection materials, a low-carbon production process, a zero-emission operation mode, and comprehensively reduces the ecological loss of power equipment.
