Coal Mine Dry Type Explosion Proof Transformer

1. Brief Introduction

In coal mine, the power source usually is 127 V, 660 V, 1140 V, 3300 V.  127 V is for illumination, control power supply. 660 V, 1140 V, 3300 V are for big size machine. But illumination common power source is 110 V, 220 V, 240 V. Therefore, the dry type transformer is neccessary.

2. Product Features

It is composed of three parts: high voltage distribution switch, minining explosion mobile transformation station, intelligent low-voltage protection box. It is explosion proof, quite safety.

3. Comparison

Compared with oil immersed transformer,  the dry type transormer unique features are 100% flame proof, no pollute (no oil leakage risk), easy to maintain (less external devices). It is suitable for mining environment.
