dry cast resin transformers
Dry cast resin transformers represent a significant advancement in electrical power distribution technology. These transformers utilize epoxy resin encapsulation to insulate and protect their core and windings, offering a robust solution for various industrial and commercial applications. The casting process involves vacuum impregnation of the windings with epoxy resin, creating a solid, void-free insulation system that provides exceptional mechanical and electrical strength. These transformers operate by converting voltage levels while maintaining high efficiency and reliability. Their design incorporates advanced cooling systems that effectively dissipate heat without the need for liquid coolants, making them particularly suitable for indoor installations. The transformers feature Class F insulation systems, capable of withstanding temperatures up to 155°C, ensuring consistent performance under demanding conditions. They are engineered to handle power ratings from 500 kVA to 25 MVA and voltage levels up to 36 kV, making them versatile enough for various applications including industrial facilities, commercial buildings, renewable energy installations, and critical infrastructure projects.
