Import Box Type Prefabricated Outdoor Power Dis — Buy in wholesale FOB from Supplier in China

Henan Yubian Electricians Co., Ltd produces box type prefabricated outdoor power distribution substations at Qianlong Industrial Park, Huixian City, Henan Province, China. These compact substations integrate medium voltage switchgear, distribution transformer, and low voltage switchgear within a single enclosed steel enclosure for outdoor installation. The rated frequency is AC 50Hz or 60Hz, with voltage 1000V and below on the circuit side. The transformer operates on electromagnetic induction principle with primary and secondary windings, where the secondary winding sits outside the primary and induced electromotive force is generated proportionally to the turns ratio.

The box type construction typically employs corrosion-resistant steel or aluminum alloy housing with internal partitioning between MV, transformer, and LV compartments. IP ratings commonly range IP33 to IP54 depending on climate exposure, though the listing does not specify. The control transformer within the assembly provides isolated power for lighting, instrumentation, and control circuits at safer voltages. Continuous long-term operation at rated load is the design basis. Standard configurations may include oil-immersed or dry-type transformers, with typical European box substation ratings from 100kVA to 1250kVA, though exact ratings for this supplier require confirmation.

Primary applications include electrical distribution for machine tools, mechanical equipment control, and general industrial/commercial lighting loads. The prefabricated format reduces on-site civil works and commissioning time versus conventional brick substations. Buyers should confirm with Henan Yubian whether they supply complete substations or transformer-only units, and whether the quoted assembly includes MV switchgear, LV distribution panels, and internal buswork. Climate-specific design for ambient temperature, humidity, and pollution level should be discussed for your installation site.

Henan Yubian Electricians Co., Ltd operates from Qianlong Industrial Park in Huixian City, Henan Province, China, postal code 453700. The company holds a harbor trust tier classification. Response metrics show 0.00% response rate with zero average response hours, suggesting minimal active engagement through platform channels. No ISO certification, export license verification, or factory audit results are present in disclosed data.

The supplier focuses on power distribution equipment including prefabricated substations and control transformers. The listing describes electromagnetic transformer operation in detail but lacks commercial specifics such as production capacity, annual output, or key accounts. Buyers should conduct independent due diligence, request factory inspection, and verify technical documentation including type test reports for short-circuit withstand and temperature rise before committing to purchase.
