ZF-72.5/126kV Wind Power–Specific Combined Electrical Apparatus, Enclosed Switchgear

To meet the system voltage upgrade requirements of new‑energy wind farms, Juhongkai has developed two compact switchgear products: the environmentally friendly ZF‑72.5 kV unit, designed for installation inside wind towers, and the compact ZF‑126 kV unit. The 72.5 kV GIS equipment employs clean‑air insulation and vacuum arc‑extinguishing technology, eliminating any greenhouse gas emissions or leaks, thereby aligning perfectly with the eco‑friendly principles of wind power as a clean energy source. Meanwhile, the 126 kV GIS device is built on high‑voltage GIS technology and represents the most compact new‑energy solution available at this voltage level worldwide.

GSR6-40.5 Eco‑friendly Gas‑Insulated Metal‑Enclosed Switchgear

The GSR6-40.5 series environmentally friendly gas-insulated metal-enclosed switchgear (C‑GIS) is a next-generation medium-voltage complete switchgear that employs clean-air insulation and vacuum arc-extinguishing technology, ensuring zero emissions and leakage of greenhouse gases. The product has successfully passed a full suite of type tests and technical assessments, securing multiple national invention and utility‑model patents, and is protected by independent intellectual property rights. It is suitable for a wide range of critical distribution and substation systems across the national economy, including transmission and transformation networks, urban power grids, new‑energy grids, petrochemical facilities, metallurgical plants, urban rail transit, and applications in extreme high‑altitude environments.

JSR6-40.5 SF6 Gas-Insulated Metal-Enclosed Ring Main Unit

JSR6-40.5 SF6 gas-insulated metal-enclosed switchgear (commonly referred to as an insulated ring main unit) is a new generation of compact medium-voltage gas-insulated switchgear developed by Juhongkai Electric through the assimilation and adaptation of advanced foreign technologies, tailored to meet the requirements of China's power supply systems. The extensive application of cutting-edge laser, sensing, and diagnostic technologies throughout the manufacturing process ensures the product's high safety and reliability.
