As a leading domestic source manufacturer of pre-fabricated power distribution equipment, Junray Electrical has dedicated years to deep cultivation within the field of compact substations. Focusing on the demand for rapid deployment in outdoor power distribution, the company has developed a series of integrated, pre-fabricated compact substation products that require no on-site civil engineering work. This innovation effectively resolves the critical pain points associated with traditional substations—namely, lengthy construction cycles, extensive land requirements, and high civil engineering costs—by providing customers with a "transport-to-site, plug-and-play" rapid distribution solution. Widely applicable across high-end commercial sectors—including power grid modernization, new energy infrastructure support, and engineering project bidding—Junray Electrical stands as one of the core suppliers in China's compact substation market.
Junray Electrical’s Box-type Substations address outdoor power distribution requirements across a wide range of scales and application scenarios, forming a complete matrix of compact substation products:
Designed for medium-scale outdoor power distribution projects, we offer standard European-style compact substations. These units integrate three core modules—high-voltage switchgear, transformers, and low-voltage switchgear—with capacities ranging from 100 kVA to 2500 kVA. Equipped with comprehensive power distribution and protection functions, they are perfectly suited for applications such as residential communities, industrial plants, and medium-scale photovoltaic power stations, enabling rapid power distribution deployment for medium-sized outdoor projects.
Tailored for small-scale outdoor power distribution projects, we offer compact American-style substations. These units feature a footprint 40% smaller than that of their European counterparts and come at a lower cost, with capacities ranging from 50 kVA to 1000 kVA. They are ideally suited for scenarios where cost-efficiency and minimal land occupation are critical—such as rural power distribution, small construction sites, and small-scale photovoltaic power stations—delivering highly cost-effective power distribution solutions for small-scale outdoor projects.
Junray Electrical’s Box-type Substations are built upon the core principles of being "Fast, Reliable, and Hassle-Free." All products are manufactured in strict compliance with national standards for compact substations—such as GB/T 17467—and every unit undergoes complete modular pre-assembly and commissioning at the factory:
Complete Pre-assembly and Commissioning: All high-voltage switchgear, transformers, and low-voltage switchgear are fully assembled, wired, and electrically commissioned at the factory. Upon delivery to the site, the unit requires only the connection of the high-voltage incoming lines and low-voltage outgoing lines to be ready for immediate operation. This completely eliminates the time typically required for on-site installation and commissioning, allowing for project deployment to be completed within just a few days.
End-to-End Quality Control: From core components to the structural enclosure, we maintain independent control over the entire production chain. Every module undergoes rigorous, comprehensive testing throughout the manufacturing process to ensure the overall reliability of the substation, eliminate potential compatibility risks between modules, and guarantee long-term, stable operation.
Commercial Adaptability: We offer flexible branding options, providing products under the "Junray" brand, as generic unbranded versions, or featuring specific designated brands as requested. This adaptability allows us to cater to diverse commercial scenarios—including engineering tenders, power grid modernization projects, and export trade—thereby fully meeting our clients' specific branding and channel requirements.
As a primary manufacturer of Box-type Substations, Junray Electrical offers its clients the following:
Professional Substation Design: We provide expert design solutions tailored to each client's specific project requirements, optimizing both cost-efficiency and system reliability.
Rapid Delivery: We guarantee delivery of customized, specialized compact substations within 25 days, meeting the demands for rapid project deployment.
