Longevity and minimum maintenance

Designed for underground coal mining applications, our flameproof dry type transformers feature non-explosive nitrogen gas to suppress arc explosions and hermetically sealed and positively pressurised tanks to prevent moisture ingress.  

The units also contain a 220°C fully co-ordinated insulation system, ensuring the insulating materials can withstand the heat generated by the core and coils. 

Our flameproof dry type transformers have a long operational life and are manufactured with minimum maintenance requirements.
