Introduction to Dry-Type Transformer – 3 Phase
SOTEK’s three-phase dry-type transformers are engineered for safe, clean, and reliable power distribution, especially in indoor and sensitive environments. Built using cast resin or vacuum pressure impregnated (VPI) insulation, our dry transformers provide excellent thermal performance, fire resistance, and environmental safety — without the need for oil-based cooling.
Dry-type transformers are ideal for locations where fire safety, compact design, and maintenance-free operation are essential. Each unit is manufactured under strict quality control and complies with IEC 60076-11 and other international standards.
