In the contemporary era of energy transition, oil-immersed transformers remain the backbone of global electrical grids. As an experienced oil immersed transformer factory, we understand that the industry is no longer just about power conversion—it's about efficiency, sustainability, and smart integration.
The global market for liquid-filled transformers is projected to reach billions by 2030, driven by rapid urbanization in SE Asia, Africa, and the massive grid renewal projects in North America and Europe.
As solar and wind farms proliferate, the demand for specialized step-up transformers is surging. Oil-immersed units are preferred for their superior cooling and longevity in harsh outdoor environments.
Modern "Green" factories are shifting toward biodegradable vegetable oils (esters) to minimize environmental risk, a trend we actively support in our R&D center.
Procurement officers and electrical engineers worldwide are increasingly looking for transformer factories that can offer more than just a product. They require compliance with international standards such as IEC 60076, ANSI/IEEE, and AS/NZS. In regions like the Middle East, heat dissipation is the primary concern; in coastal South America, corrosion resistance is paramount. Our factory addresses these localized needs through customized insulation and reinforced tank designs.
At Zhejiang Tanaka Electric Co., Ltd., our production philosophy centers on "Zero Defects." Our facility is equipped with state-of-the-art CNC automatic winding machines and static vacuum casting systems. This ensures that every coil is wound with mathematical precision, reducing partial discharge and extending the life of the transformer.
Our amorphous alloy core technology (as seen in our 10kv Amorphous Foil Coil series) reduces no-load losses by up to 70% compared to traditional silicon steel cores, making it a favorite for energy-conscious industrial clients.
Zhejiang Tanaka Electric Co., Ltd. is a high-tech enterprise specializing in the production, research and development, and sales of transformers and related products. The company's registered capital amounts to 110 million RMB. It has a strong technical team with 15 senior engineers, over 30 intermediate technicians, and 17 senior technicians. The powerful technical strength provides a solid guarantee for the research and production of products.
In recent years, the company has continuously increased investment in technical strength and modern equipment. Currently has more than 120 sets of various equipment, including CNC automatic winding machines, CNC static vacuum casting, Automatic foil winding machines, Microcomputer-controlled gradient curing furnaces, etc., and continuously optimize production processes.
