With the global energy conservation and emission reduction strategy advancing and the continuous upgrading of urban and industrial power distribution systems, high-efficiency, low-consumption, safe and environmentally friendly power equipment has become the core development trend of the power industry. As key power conversion equipment, traditional power transformers have long faced prominent bottlenecks in actual operation. Conventional oil-immersed transformers have mature basic technology, but they rely on insulating oil for heat dissipation and cooling, bringing hidden dangers such as oil leakage, fire risks and environmental pollution. Meanwhile, frequent oil replacement, routine inspection and equipment maintenance greatly increase long-term operating and maintenance costs for power projects.

In addition, traditional box-type substations and amorphous alloy transformers also have obvious application limitations. Box-type power distribution equipment features high integration but suffers from bulky volume and poor flexibility, leading to difficult transportation and on-site installation in urban compact areas, park construction and old community renovation scenarios. While amorphous alloy dry-type transformers deliver good energy-saving performance, their complex manufacturing process and poor universality make them hard to popularize and apply on a large scale in 10KV voltage-level power distribution scenarios, restricting the overall energy efficiency upgrade of the power grid.

To target the above industry pain points and meet the market’s demand for low-carbon, safe and low-maintenance power equipment,Jiangsu Hualai Electrical Technology Co., Ltd. has officially launched the optimized and upgraded 10KV high-efficiency dry-type transformer. Abandoning the traditional oil-cooling structure, this new-generation transformer adopts epoxy resin casting insulation technology and optimized electromagnetic design, completely eliminating hidden risks such as insulating oil leakage and flammability. It thoroughly solves the high maintenance cost and environmental pollution problems of traditional oil-immersed transformers, and fills the market gap of large-scale applicable high-energy-saving equipment in the 10KV power distribution field.

Equipped with high-quality low-loss silicon steel sheets and a scientific three-dimensional winding core structure, the 10KV dry-type transformer effectively reduces no-load loss and load loss, with overall energy consumption far exceeding industry standard levels. It achieves efficient energy saving throughout the full operation cycle and creates significant economic benefits for users. Adopting compact miniaturized integrated design, the equipment features small footprint, light weight and strong adaptability, realizing flexible installation indoors, outdoors and in limited space scenarios. Matched with an intelligent air-cooling heat dissipation system and high-grade insulation materials, it can operate stably for a long time under high-load and continuous power supply conditions, with strong operational stability and anti-interference ability.

Thanks to its outstanding advantages of energy efficiency, environmental protection, safety and zero oil maintenance, the 10KV dry-type transformer has been widely promoted and applied in various key scenarios. It covers urban commercial complexes, residential communities, industrial parks, school and hospital power distribution systems, as well as environmentally sensitive areas such as scenic spots and ecological reserves. It effectively improves the operational reliability and energy utilization efficiency of the regional power grid, helps reduce carbon emissions in the power industry, and provides solid equipment support for the construction of green and low-carbon power systems.
