In today's era of increasingly strict environmental policies, even a small amount of greenhouse effect cannot be tolerated by the power grid construction in the core urban areas. As a leading electrical equipment manufacturer in China, Junray Electrical of Wenzhou has innovatively launched the AIR-12 Dry Air-Insulated Ring Main Unit. We have abandoned traditional SF6 and mixed gases and solely used pure dry air as the insulating medium, achieving true zero greenhouse gas emissions.

With the increasing global attention to climate change, traditional SF6 gas, due to its extremely strong greenhouse effect, is facing strict control and elimination. Junray Electrical, as a leading electrical equipment manufacturer in China, responds positively to the call for green power grid construction and introduces the GIS Eco-friendly Gas Cabinet. We innovatively use dry air or N2/SF6 mixed environmentally friendly gas instead of pure SF6. While complying with increasingly strict environmental policies, it also retains the fully sealed and maintenance-free characteristics of the gas-filled cabinet.

In environments characterized by high humidity, heavy dust, and coastal salt mist, standard ring main units (RMUs) quickly succumb to water and dust ingress, leading to equipment failure and the need for frequent maintenance. The SF6 Gas Insulated RMU manufactured by Junray Electrical is a fully sealed, gas-filled device specifically engineered to withstand such harsh conditions. By hermetically sealing all high-voltage components within an SF6 gas compartment, it achieves an ultra-high protection rating of IP67—offering robust resistance against water, dust, and salt mist. Perfectly suited for the most demanding environments, this maintenance-free solution eliminates the need for frequent inspections, making it the premier choice for power distribution in harsh settings.

Junray Electrical, as a professional manufacturer, supplier and factory of HXGN17-12 Metal-Enclosed Ring Main Unit in China, focuses on the research and development of small 10kV ring network upgrading equipment. This product is an improved and upgraded version of the ordinary HXGN ring network cabinet. It adopts mature SF6 load switches, with better performance, higher reliability and smaller size. It is suitable for small 10kV ring network scenarios with high requirements for reliability.

Many large factories and substations cannot solve the power factor problem on the high-voltage side through low-voltage reactive power compensation. The TBBZ Automatic Reactive Power Compensation Device of Junray Electrical is a high-voltage-specific compensation device specially developed for high-voltage side reactive power compensation. It is designed for 10kV and 35kV high-voltage sides, automatically compensating for the reactive power of high voltage and pulling the power factor on the high-voltage side to above 0.95, completely solving the reactive power penalties on the high-voltage side. Compared with low-voltage compensation, its effect is better and it is more suitable for large-scale high-voltage distribution scenarios.

The KYN550-12 AC Metal-Enclosed Switchgear is the most compact complete set of power distribution equipment offered by Junray Electrical, designed for use in 12kV three-phase AC 50Hz single-busbar and single-busbar sectionalized systems.It is primarily utilized in substations requiring miniaturization—such as those found in commercial and industrial buildings, real estate developments, data centers, and various other industrial power grids.
