Mining transformers

Function
Mining transformers are designed to supply electrical equipment operating in demanding environmental conditions typical for the mining industry. As standard, they are adapted for mounting using fixing brackets, facilitating installation in various underground systems and structures.
Current terminals can be positioned on one or both sides of the transformer, allowing flexible adaptation to the connection layout. Upon request, transformers can be equipped with enclosures rated IP23, IP44 or IP54, increasing resistance to environmental factors such as humidity, dust and temperature fluctuations.
 
Benefits
  • High level of operational safety in mining environments
  • Energy efficiency and stable operation under load
  • Resistance to harsh environmental conditions
  • Reliability even during long-term operation
Applications
  • Mining industry
