Our European-style box-type substation provides a reliable power solution specifically engineered for modern photovoltaic power generation needs. This advanced combined transformer securely integrates the main transformer, load switch, and high-voltage fuse directly into the transformer tank. By utilizing the internal insulating fluid as a highly effective cooling and insulation medium, we deliver a highly compact and secure system. It is designed to meet the growing global demands for clean energy infrastructure with exceptional operational stability.

Selection of the primary system for combined transformers
Our photovoltaic power substation utilizes a completely sealed tank design that entirely eliminates the need for a traditional oil conservator. This robust construction ensures that no core lifting is required during standard maintenance procedures. The integrated enclosure design effectively protects sensitive internal electrical components from external environmental factors.
The external casing undergoes an intensive multi-stage protective process involving precise sandblasting, pickling, and phosphating. We apply separate layers of primer, intermediate coat, and topcoat to the ZGS-ZT series combined transformer. This meticulous surface treatment provides outstanding durability, UV resistance, and corrosion resistance that easily exceeds the strength of ordinary coatings.
Compared to traditional dispersed power distribution setups, our engineered system offers an exceptionally small footprint and light overall weight. This streamlined design ensures rapid deployment and incredibly easy installation across various demanding project sites. Engineering teams can significantly reduce their initial setup time and concrete foundation construction costs.
The 10kV combined transformer features a high-voltage backup current-limiting fuse paired with an insertable overload protection fuse. For higher capacity requirements, our 35kV combined transformer incorporates a novel high-voltage current-limiting fuse boasting remarkably high breaking capacity. Both configurations deliver reliable, full-range electrical protection for the entire operating unit.
We specifically design our equipment to support the rapid expansion of domestic and international clean solar energy production. Our reliable units effortlessly manage the unique power conversion and supply demands of large-scale photovoltaic farms. They ensure consistent and safe energy transmission from ground solar arrays directly to the main utility grid.
Thanks to the exceptional weather resistance of the treated casing, this unit performs flawlessly in demanding outdoor industrial environments. The robust physical protection allows continuous operation regardless of intense sunlight exposure or potentially corrosive atmospheres. We deliver dependable power distribution solutions for remote, harsh, or challenging industrial facility locations.
