Mv And Hv Dry Type Transformer

For industrial and commercial power distribution demanding the highest standards of safety and reliability, our MV and HV dry type transformers offer a superior, 10/0.4kv Dry Type Transformer solution. Designed with flame-retardant, self-extinguishing materials and free from hazardous oils, they provide an environmentally clean and maintenance-friendly option for installations with stringent fire safety requirements, such as hospitals, high-rises, and data centers. Our engineering focuses on achieving exceptional efficiency through advanced core and coil designs, directly reducing operational energy costs and heat dissipation. For projects with substantial power needs, our robust 1500kva Dry Type Transformer units deliver consistent, stable voltage transformation, capable of handling heavy loads with minimal losses. The inherent simplicity of the dry type design eliminates the risk of oil leaks and the associated cleanup or soil contamination, while the open-ventilated or enclosed construction allows for flexible placement closer to the load center, optimizing your facility's layout and reducing cabling expenses.


Our MV and HV Dry Type Transformer product line is engineered with precision to meet diverse application challenges. The construction utilizes high-quality, thermally upgraded insulation systems (typically Class F, H, or C) that ensure long operational life even under demanding thermal stresses. The windings are meticulously crafted from copper or aluminum conductors, vacuum pressure impregnated (VPI) with premium resin to provide superior dielectric strength, excellent moisture resistance, and protection against environmental contaminants. The core is assembled from high-grade, grain-oriented silicon steel laminations, meticulously cut and stacked to minimize core losses and reduce audible noise levels. For enhanced safety and performance monitoring, standard and optional features include temperature control systems with PT100 sensors, forced air cooling (FA/FO) for increased overload capacity, and comprehensive protection devices. This transformer is designed for easy installation and requires minimal routine maintenance, offering a total cost of ownership advantage over its liquid-filled counterparts.

Key Product Specifications
