What medium-voltage equipment does a mine use?
Mining operations use medium-voltage switchgear, transformers, cable splices and terminations, and grounding to power draglines, shovels, conveyors, ventilation, and processing plants.
Much of the distribution is mobile — substations and switchgear move as the operation advances — and the feeders they serve run across dusty, wet, and mechanically harsh ground.
What regulations govern mine electrical systems?
Mine electrical systems are regulated by the Mine Safety and Health Administration (MSHA) under 30 CFR.
Part 18 covers MSHA approval of electric motor-driven mine equipment and accessories intended for use in gassy mines or tunnels. Part 23 covers telephones and signaling devices. Part 75 sets the mandatory safety standards for underground coal mines, including Subpart F (electrical equipment — general) and Subpart I (underground high-voltage distribution).
Equipment compliance is determined per installation — confirm the applicable MSHA requirements against the project specification at quote.
Why does mining equipment need special consideration?
Mines are dusty, wet, and mechanically harsh, and much of the distribution is mobile rather than fixed.
Equipment selection accounts for the environment and for the MSHA requirements that apply to the specific installation — ratings, enclosure construction, and compliance are confirmed per project at quote.
Does Hawk publish pricing for mining projects?
No. Equipment is configured and priced per project.

Medium-voltage equipment for surface and underground mining.
Mining operations distribute medium-voltage power to draglines, shovels, conveyors, ventilation, and processing plants — often through mobile substations, and across dusty, wet, and mechanically harsh environments. Mine electrical systems are regulated by the Mine Safety and Health Administration under 30 CFR: Part 18 covers approval of electric motor-driven mine equipment and accessories intended for use in gassy mines or tunnels, Part 23 covers telephones and signaling devices, and Part 75 sets the mandatory safety standards for underground coal mines — Subpart F for electrical equipment generally and Subpart I for underground high-voltage distribution. Equipment compliance is determined per installation and confirmed against the project specification.
The medium-voltage scope Hawk MV Supply sources for mining covers switchgear sectionalizing and protecting mine distribution, distribution transformers at substations and load centers, cold-shrink and heat-shrink cable splices and terminations on the primary feeders, and the grounding rods, clamps, conductors, and connectors behind substation ground grids and equipment frame grounding. Manufacturers carried for this work include G&W Electric, JST Power Equipment, Cooper Power Series (Eaton), Richards Manufacturing, 3M, and TE Connectivity.
