Mine transformer

Overview

Mining transformers are divided into general type and flameproof type. The general type is used in mines where there is coal dust and biogas without explosion, and it is designed to be powered by electric power and lighting. Explosion-proof transformers are used in mines where there is danger of explosion. This transformer is dry type.
