Junray Electrical, as a professional manufacturer, supplier and factory of American-style substations in China, focuses on the research and development of small pre-assembled substations. This product is 40% smaller in volume and 30% cheaper than European box-type transformers. It is pre-assembled and integrated, with IP54 outdoor protection. It can be deployed in a few days and is perfectly suitable for small outdoor power distribution scenarios such as rural areas and small construction sites. It does not require large space or high cost and is the preferred equipment for small-scale outdoor power distribution.

Junray Electrical is a professional Manufacturer, Supplier and Factory of European Style Compact Substation in China. It focuses on the research and development of outdoor pre-assembled box-type substations. This product integrates high-voltage cabinets, transformers and low-voltage cabinets. It is factory-pre-assembled and ready for immediate use upon on-site wiring. It can be deployed in just a few days, occupying 70% less space than ordinary substations. It has IP54 outdoor protection, is more cost-effective, and is the standard configuration for outdoor power distribution.

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.
