11kv 3 phase 1000kva dry type distribution transformer Application scenarios
1000kva dry type distribution transformers have the characteristics of being oil-free, fireproof, and explosion-proof. They are suitable for installation in indoor environments, especially in places with dense populations and strict safety requirements. Typical application scenarios include: residential communities, commercial complexes, office buildings, data centers, hospitals, schools, and stations, etc.
Oil-immersed transformers are widely used in outdoor substations, heavy industry, and other fields because their voltage levels and capacities are not limited. At the same time, oil-immersed transformers adopt a fully sealed structure, which has stronger adaptability to harsh environments such as sand, wind, rain, snow, and high temperatures, making them particularly suitable for outdoor use. Typical application scenarios include: power plants, substations, urban and rural power grids, heavy industry enterprises, wind power, and photovoltaic projects, etc.

11kv 3 phase 1000kva dry type distribution transformer Manufacturing Process
The coils are wound on high-precision winding machines, and the low-voltage windings adopt a foil winding structure. Ventilation channels are provided for transformers with larger capacities. After winding, vacuum drying is performed. The entire pouring and curing process is carried out in strict accordance with process requirements, and all steps are closely monitored and adjusted as needed.The precision manufacturing of the pouring process ensures that the coils are free of bubbles and voids,resulting in high-quality finished transformers.
