Guoxiang Electric's 11kV Oil-Immersed Distribution Transformer Addresses Outdoor Pain Points for All-Weather Reliable Power Distribution
Jiangxi Guoxiang Electric Power Equipment Co., Ltd. has launched its11kV outdoor-specific oil-immersed distribution transformer, featuring a fully sealed weather-resistant structure and low-loss energy-saving design. Manufactured in strict compliance with IEC international standards, the product adapts to diverse outdoor scenarios including urban and rural distribution grids, industrial and mining sites, and new energy power stations. It is now officially available for global supply and channel cooperation.
Designed to resolve pervasive pain points for outdoor electrical equipment—including insulation moisture damage, enclosure corrosion, and inadequate heat dissipation—this series features a fully sealed corrugated tank finished with a multi-layer anti-corrosion coating, delivering an IP55 Protection rating. Internally, high-purity insulating oil is paired with a layered insulated winding structure to deliver exceptional lightning impulse resistance and short-circuit withstand capacity.
In terms of energy efficiency and service longevity, the transformer core is constructed from high-grade cold-rolled grain-oriented silicon steel, and a step-lap stacking process minimizes no-load losses to meet leading global energy efficiency benchmarks, delivering significant long-term savings on electricity costs. Vacuum drying and vacuum oil filling processes eliminate internal moisture and air bubbles, while the fully sealed design prevents external contaminants from entering the unit. Under standard operating conditions, the transformer delivers a service life of over 25 years and cuts routine operation and maintenance costs by more than 30%, enabling low-maintenance or near maintenance-free performance.
The full product line covers a rated capacity range from 20kVA to 2500kVA, with fully customizable specifications including voltage class, voltage regulation method, cooling mode, and winding material. It supports both ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced) cooling configurations to suit varying load requirements, making it suitable for grid upgrades, industrial power supply, new energy grid integration, and temporary power for infrastructure projects. The solution has already been field-proven in overseas projects across South America, Africa, and Southeast Asia.
For quality assurance and delivery, all units are built to meet both IEC 60076 international standards and GB national standards. Every transformer undergoes a comprehensive suite of factory tests—including no-load, load, and insulation withstand voltage testing—before shipment, and is supplied with full export inspection documentation and technical files. Standard models are kept in stock for fast delivery within 7–15 days, while custom configurations can be delivered in 20–30 days. We support all mainstream international trade terms, including EXW, FOB, CIF, and DDP.
