Mine Power Center Rebuild Services

Is Your Mine Power Center Becoming Rundown and Unreliable?

Has it been out of service for an extended period of time, perhaps stored in less than ideal conditions, exposed to harmful dust, moisture and sunlight? Atlas Electric is here to help. Our rebuild program will extend the life and dependability of each unit, reducing maintenance costs and downtime.

Send us your Mine Power Center and we will give you a no cost preliminary evaluation. Our experienced technicians will examine and test the major components allowing us to give you a cost estimate prior to a commitment from you to proceed.

Our rebuild process will consist of the following:

• Dismantle and remove all components and wiring from the enclosure.
• Clean and sandblast the enclosure inside and out.
• Test, clean and bake the power transformer core and coil.
• Clean and test the surge arrestors, load break switch and fuses.
• Clean and test circuit breakers, ground fault monitors and receptacles.
• Clean and test low voltage transformer, panel and receptacles.
• Clean and test neutral grounding resistor.
• Clean and test lid switches and e-stop.
• Repair or replace components as needed.
• Paint the enclosure inside and out (your choice of color).
• Reassemble and replace all the low and medium voltage wiring.
• Provide new rebuilt electrical drawings.
• 1 year warranty on labor and replacement components.

In addition we can make modifications such as installing main breakers, additional feeder breakers, neutral grounding resistor monitors, meters, ground fault monitor upgrades and arc flash mitigation upgrades.
