Mining (Explosion-Proof)

Explosion-proof and heavy-duty transformers for surface and underground mining operations.

Built for the Toughest Environments

Built for the Toughest Environments

Mining operations present unique challenges: remote locations, extreme overloads, corrosive atmospheres, methane-rich underground environments, and zero tolerance for unplanned downtime.

Our mining transformers range from flameproof underground units certified to IEC 60079, to heavy-duty surface substation transformers with extended creepage bushings for high-altitude sites, conservator tanks with silica gel breathers, and Buchholz relay protection.
