Longwall Substations

View our high performing longwall substations designed to support reliable power distribution at the coal face. 

Custom and compliant

Developed as part of a complete electrical package for longwall systems, our longwall substations are available in either flameproof or ingress protected (IP66) variations and can facilitate 11kV/3.3kV up to 7.5MVA.  

Each longwall substation is manufactured with a High Tension (HT) enclosure for necessary electrical protection equipment, a nitrogen-filled dry type transformer, and a Low Tension (LT) enclosure for communication and control devices.  

The complete substation is typically supplied on a powered track mounted skid with rated lifting facilities to allow for easy relocations around a site.
