Wuhan Goldhome Hipot Electrical Co., Ltd. promotes SF6 gas processing technology through reliable vacuum pump solutionsIn the field of high-voltage testing, standardization of SF6 gas management is of utmost importance for both equipment performance and environmental safety. The SF6 gas vacuum pump equipment series developed by Wuhan Goldhome Hipot Electrical Co., Ltd. is designed to help power companies and maintenance teams manage SF6 gas in an efficient and safe manner. Specially designed to meet the requirements of modern electrical systems, these devices meet critical industry standards for reliability and compliance with environmental requirements.
Why SF6 purity and recovery are more important than ever
SF6 gas is irreplaceable in high-voltage systems due to its excellent insulating and arc-quenching properties, but it is subject to strict regulatory controls due to its global warming potential (GWP), which is 23,500 times greater than that of CO₂. Meanwhile, oil contamination, even in trace amounts, degrades the performance of SF6, leading to equipment corrosion, partial discharge, and unplanned outages. International standards such as IEC 60480 already specify ≤5ppm oil content for recycled SF6, while power utilities are increasingly demanding ≥99% recovery rates to minimize waste and costs.
Conventional SF6 vacuum pumps often fail to meet these requirements: low recovery efficiency leads to gas waste, while inadequate filtration results in oil-contaminated gas that fails compliance checks. Goldhome Hipot's new device directly addresses these issues, as it has been specifically developed for large power grids, transformer manufacturers, and GIS maintenance teams.
Key innovations: cleanliness, efficiency, and intelligence
Based on Goldhome Hipot's more than 20 years of expertise in high-voltage equipment, the GH-SF6-60 integrates the industry's leading technologies to meet the latest industry requirements:
- 5 ppm ultra-low oil content filtration: Equipped with a two-stage filter system – coalescing filters capture microscopic liquid oil droplets, while activated carbon adsorbs dissolved oil vapors – it continuously provides SF6 gas with ≤3 ppm oil content, far exceeding the 5 ppm threshold value of IEC 60480. The built-in laser oil content analyzer provides real-time monitoring and sounds an alarm when approaching the purity limit to prevent unsuitability.
- 99% recovery rate and high performance: Equipped with a 60 m³/h oil-free, water-cooled compressor and a vacuum pump with a pumping speed of 31.3 m³/h, the device achieves a final vacuum level of 1 mbar. It features negative pressure recovery and bottle rotation functions (compatible with 40-500 liter bottles), minimizing residual gas in equipment and bottles to increase recovery efficiency to 99%.
- Dual tank design for purity isolation: Utilizing a patented dual-tank design (separate storage of new and recycled SF6), the equipment prevents cross-contamination between fresh and reclaimed gases and solves a long-standing problem in the industry where impure recycled gas degrades the quality of new SF6.
- On-site adaptability and intelligence: The self-propelled design with automatic loading/unloading (equipped with an electric drive) allows for easy movement in substations and on construction sites. The 12-inch industrial touchscreen displays vacuum level, oil content, and regeneration process in real time; data can be synchronized with LIMS/MES systems via Ethernet/USB and supports automatic compliance reporting.
Environmental & Economic Value for Industrial Users
For power utilities and manufacturers, the GH-SF6-60 delivers tangible benefits beyond compliance:
- Green Operations: By maximizing SF6 reuse and minimizing emissions, the device helps enterprises meet carbon neutrality goals. A single unit can reduce SF6 consumption by 50kg annually for a medium-sized power grid-equivalent to cutting 1.175 million kg of CO₂ emissions.
- Cost Savings: 99% recovery reduces the need for new SF6 procurement, while the 5ppm purity ensures recycled gas can be directly reused in high-voltage equipment, lowering gas costs by 30% per year.
- Reduced Downtime: One-click automated operation (voltage boosting, timing, data recording) cuts maintenance time by 60% compared to manual systems. The modular design allows quick replacement of filters and electrodes, minimizing equipment downtime.
