Are you a professional OEM electrical equipment manufacturer?

Yes, we are a reliable OEM electrical equipment manufacturer with over 15 years of manufacturing experience. As a top ODM transformer factory, we provide full custom design & OEM production for transformers, RMU, MV LV switchgear and compact substations to global electrical contractors and distributors.

As a one-stop OEM electrical equipment manufacturer, we support two core custom solutions: ODM independent design and OEM private label production. Our ODM service covers electrical schematic design, cabinet structural adjustment and voltage customization (11kV/33kV/66kV). As a professional switchgear OEM supplier, we also offer brand printing, custom packaging and exclusive nameplate customization.

This OEM electrical equipment manufacturer can customize all series power distribution OEM ODM products, including oil immersed & dry type transformers, SF6 ring main unit, high & low voltage distribution cabinets, compact prefabricated substations and EV charging power equipment. We are a professional custom electrical substation manufacturer and MV LV switchgear factory for overseas engineering projects.

Absolutely. Our OEM electrical equipment manufacturer has a professional engineering team to offer full technical support. As an experienced ODM transformer factory, we can provide IEC standard drawings, project-based power distribution solutions and remote on-site installation guidance for all customized orders.

Yes. Our OEM electrical equipment manufacturer accepts both small trial OEM orders and large batch mass production. Whether you are a new distributor or EPC engineering company, we can match flexible production plans as a trustworthy ring main unit OEM supplier and custom electrical substation manufacturer.

Our OEM electrical equipment manufacturer owns complete global export certifications including ISO9001, CE, UKCA, SASO, EAC and full IEC type test reports. All OEM & ODM power distribution equipment from our MV LV switchgear factory meets international standards for Europe, Middle East, Southeast Asia and Africa markets.

As a large-scale OEM electrical equipment manufacturer with a 30,000㎡ production workshop, standard OEM production orders take 15–25 working days. Complex ODM custom design projects will confirm the exact lead time with you after finalizing technical drawings as a professional ODM transformer factory.

Sure. Our OEM electrical equipment manufacturer can modify equipment parameters for coastal humid, high temperature, desert and mining environments. As a professional switchgear OEM supplier and custom electrical substation manufacturer, we can adjust IP protection grades, insulation materials and heat dissipation structures for special projects.

After OEM order delivery, our engineering team offers long-term free technical consultation service. If customers encounter installation, wiring or operation problems on site, we provide remote video guidance at any time. For large overseas projects, we can arrange professional electrical engineers to fly to the construction site for on-site training and equipment debugging. We supply spare parts at factory cost within 10 years for all customized transformers, ring main units and switchgears. When customers need equipment upgrade or parameter modification in later years, we support secondary ODM reconstruction based on original product structure to save re-production cost.

Grid Standard Customization For Global Markets

Different countries and regions adopt distinct voltage, frequency and grid connection standards, and we adjust all power equipment parameters to match local power grid requirements.

 

For European markets, our MV LV switchgear factory designs products to fit 50Hz 400V low voltage and 11kV/24kV medium voltage grid norms, fully complying with EN electrical standards. For Middle East projects, we optimize transformers and ring main unit OEM supplier solutions to adapt high-temperature desert environments and 60Hz power frequency.

 

Our ODM transformer factory can modify core winding, cooling systems and protection components to satisfy grid codes from Southeast Asia, Africa, Australia and North America. Whether you need 33kV industrial transformers for mining projects or compact substation for solar power plants, we will finish all parameter adjustments before mass production. We also provide official grid test reports to help customers pass local customs and power bureau acceptance.

Full Supporting Documents & Export Packing Service

Besides hardware customization, we supply complete supporting documents for global export clearance. Every batch of OEM power equipment is attached with detailed technical datasheets, wiring diagrams, operation manuals and IEC test certificates. All files support multi-language translation including English, Spanish, Arabic and French, to match overseas engineering teams’ daily work.

 

For packaging, we adopt seaworthy fumigated wooden cases and anti-collision foam lining to avoid damage during long ocean transportation. We can print customer’s private logo, company information and shipping marks on the outer package as required. For bulk orders, we provide container loading plan and packing list to help customers arrange logistics efficiently. Small trial orders use lightweight reinforced cartons to cut down international shipping cost.
