Product Description

The cast resin dry type transformer is a type of SC(B) dry transformer with epoxy resin, widely used in various industrial applications. Its winding surface consists of high-quality protective material that forms a durable cover, ensuring reliable performance even in harsh environments with dust and humidity.

This transformer utilizes advanced resin casting technology where coils are cast in a vacuum state using specialized equipment. The epoxy resin serves as an insulating material, making it also known as an epoxy cast resin dry type transformer.
