Xuzhou, Jiangsu, China – July 2, 2026 Jiangsu Hualai Electric Technology Co., Ltd., a professional OEM/ODM manufacturer and direct factory supplier of electrical power equipment, announces full-spectrum production capacity for dry-type transformers, oil-immersed distribution transformers, and custom low & medium voltage switchgear cabinets, catering to global energy infrastructure buyers, electrical contractors, power utility companies, and industrial project developers worldwide.

As a vertically integrated factory with complete in-house metal fabrication, winding, assembly, and quality testing workshops, Hualai Electric eliminates middleman costs to deliver cost-effective, fully customizable electrical equipment to overseas markets across Southeast Asia, Europe, Africa, the Middle East, and Latin America. Our three core product lines cover the full chain of power transformation and distribution, as showcased in our state-of-the-art production facility:

1. Custom LV/MV Switchgear Cabinet Workshop

Our spacious fabrication workshop features mass production of modular metal-enclosed switchgear panels, distribution boxes, and control cabinet housings. All cabinet frames adopt thick cold-rolled steel with anti-corrosion electrostatic spraying, supporting fully bespoke sizing, layout design, window cutouts, door configurations, and busbar compartments per client’s electrical schematic requirements. We manufacture complete empty enclosure frames and finished assembled switchgear for low-voltage power distribution, industrial control, commercial building power supply, and renewable energy power stations. Flexible MOQ options are available for small project orders and bulk large-scale infrastructure tenders, with strict dimensional tolerance control to guarantee seamless assembly of circuit breakers, meters, relays, and busbars.

2. High-Efficiency Dry-Type Distribution Transformers

Hualai’s star product series – cast resin dry-type transformers – are fully visible in our assembly workshop, with core-coil units in flame-retardant epoxy resin casting. Designed for indoor applications including high-rise buildings, hospitals, data centers, underground metro systems, chemical plants, and photovoltaic energy storage stations, these transformers deliver zero fire hazard, low noise, strong humidity resistance, and minimal maintenance demands. Key technical advantages for global clients:

· Rated capacity ranging from 50kVA to 30,000kVA

· Compliant with IEC 60076 international standards

· Low partial discharge, high insulation class F/H

· Custom voltage ratios (10kV, 20kV, 33kV primary side options)

· Equipped with temperature control fans and over-temperature protection systems Our factory completes full winding, casting, assembly, and routine testing in-house to cut lead times and stabilize product quality for overseas bulk shipments.

3. Energy-Saving Oil-Immersed Distribution Transformers

For outdoor power grid, rural electrification, mining, and industrial park projects, our oil-immersed distribution transformers provide reliable, cost-efficient power conversion. The full corrugated radiator tank structure optimizes heat dissipation, while high-permeability silicon steel cores greatly reduce no-load loss to meet global energy efficiency standards. We support custom design for single-phase & three-phase oil transformers with capacities from 10kVA up to 50,000kVA, matching regional grid voltage standards for different countries. Every unit undergoes strict no-load loss, load loss, insulation withstand, and leakage testing before packaging, ensuring stable operation under harsh outdoor climate conditions from high-temperature deserts to rainy coastal zones.

Factory & Global Service Advantages as Direct Manufacturer

Unlike trading companies, Jiangsu Hualai Electric holds full production lines covering sheet metal processing, transformer core winding, resin casting, oil tank welding, electrical assembly, and lab performance testing, bringing core benefits to international buyers:

1. Factory Direct Pricing: No intermediate markup; competitive factory ex-work rates for bulk orders

2. Full Customization: Adjust voltage, capacity, cabinet size, protection functions, paint color, and logo marking to match local market standards

3. International Certifications: Products meet IEC, ISO9001 quality management standards; support third-party testing reports for tender bidding

4. Flexible Logistics & Packaging: Export-grade fumigated wooden case packaging, cooperation with major freight forwarders for sea/air door-to-door delivery

5. Dedicated Overseas Support Team: Multilingual sales & technical engineers provide one-stop solutions from drawing design, quotation, production tracking to after-sales troubleshooting
