Wuhan Goldhome Hipot Electrical Co., Ltd. promotes green initiatives through SF6 gas recovery units
Wuhan Goldhome Hipot Electrical Co., Ltd. continues to lead the way in sustainable solutions in the high-voltage testing sector through its SF6 gas recovery units. These units play a crucial role in the maintenance of gas-insulated power systems, enabling professionals to efficiently recover and reuse SF6 gas. By supporting environmentally friendly practices, the units help reduce greenhouse gas emissions and lower operating costs.
Fundamental technological innovation: Recovery rate of over 99.5% with almost zero residue
Compared to traditional equipment, the KDQH-66 device launched by Goldhome Hipot has achieved a number of technological innovations. According to the head of Goldhome Hipot's research and development team, the device uses integrated double compression and nitrogen circulation flushing technology, which radically solves the problem of SF6 gas residues in the device's pipes. "Traditional regeneration methods typically leave 3%–5% SF6 gas, but our device can reduce the final regeneration pressure to ≤53 kPa, increasing the regeneration rate to over 99.5%," said the team leader. With a volume of 1 m³ of SF6 gas at an initial pressure of 0.8 MPa, the device can complete regeneration in less than 2.5 hours, which is 40% more efficient than similar products.
For gas purification, the device is equipped with a multi-layer composite filtration and adsorption system and can effectively remove impurities, moisture, decomposition products, and oil from SF6 gas. After a single regeneration and cleaning cycle, the moisture content in the gas is regulated to below 60 PPM/V, the oil content to below 10 PPM/V, and the purity to 99.9% or higher, fully meeting the reuse standards for energy equipment. The device's built-in drying and regeneration system enables the dryer to be activated and reused without replacement, significantly reducing maintenance costs and the amount of waste disposed of into the environment.
Human-centered design: adaptation to different field working conditions
Focusing on the real needs of field operations in the electrical sector, the KDQH-66 device strikes a balance between performance and usability thanks to its human-centered design. The machine's compact dimensions and sensible weight distribution make it mobile and easy to push by hand. The device is equipped with high-quality wheels, allowing it to be easily moved even in confined spaces such as transformer stations, while effectively protecting the floor from scratches.
The device offers significant advantages in terms of environmental adaptability. It uses air cooling, does not require an external water source, and operates stably in temperatures ranging from -10 °C to 40 °C. The built-in temperature protection system and automatic phase sequence conversion function can prevent equipment failures caused by extreme temperatures or power supply phase sequence errors. The integrated electrical system uses high-quality branded components, with a continuous trouble-free operating time of more than 1000 hours and a cumulative trouble-free operating time of more than 5000 hours, ensuring long-term reliability in the field.
In addition, the device is equipped with a digital vacuum gauge and an intelligent control panel that performs vacuuming, recovery, cleaning, and inflation at the touch of a button. The operating process is intuitive and simple, reducing the difficulty of operation and the possibility of human error. The overall noise level of the machine is below 75 dB(A), creating a more comfortable working environment for operators.
Green Value Comes to the Fore: Helping the Power Industry Achieve Emissions Reduction Targets
The launch of the KDQH-66 sulfur hexafluoride gas recovery and refilling unit has drawn significant attention within the power industry. A representative from a major state-owned power grid company stated that the widespread adoption of this equipment will effectively reduce sulfur hexafluoride gas emissions during equipment maintenance and replacement, promoting the recycling of sulfur hexafluoride gas in the power sector.
Estimates indicate that deploying 1,000 KDQH-66 units across China's power grid could recover and reuse over 150,000 metric tons of SF₆ annually-equivalent to reducing carbon dioxide emissions by tens of millions of tons. This holds significant importance for accelerating the power sector's green transition and achieving its dual carbon goals.
As part of its ongoing innovation, Goldhome Hipot has introduced training programs to help clients maximize the benefits of the SF6 gas recovery system. These sessions cover best practices for gas handling, equipment upkeep, and compliance.
