BC2/BC3 CONVERSION TO UNDERGROUND
Client:
Great Lakes Energy
Location: Boyne City, Michigan
Project consisted of the conversion of double circuit 12.5kV line from
Boyne City Substation for one-half mile to new accessible riser
poles. The existing overhead double-circuit line requiring
reconstruction was highly susceptible to outages from the narrow
corridor with dense vegetation. The centerline also crossed a
stream, wetlands, and conservancy property. The circuits were
reconstructed underground for increased reliability and included twin
1500’ directional bores to cross the sensitive areas. Fused
cabinets for all taps and transformers were installed along with fault
indicators at critical points.
