Glass Ranch Substation

Glass Ranch Substation

October 9, 2015

Power Line Services is serving as subcontractor to Burns & McDonnell for the construction of this greenfield 138–25kV substation for Sharyland Utilities. Glass Ranch Substation will have a six-position ring bus arrangement with five 138kV circuit breakers installed.

The initial 138kV build-out includes two Sharyland Utilities line terminals with OPGW for fiber optic communications, one to Tall City Substation and one to Sale Ranch, plus two 138kV capacitor banks, two 138–25kV transformers and a mobile subposition. Each transformer will feed a four-circuit distribution line-up.

The project will also involve the installation of eight 1200A distribution breakers, conduits and cables from the distribution bays to feeder risers located outside the substation security fence. A 25kV tie breaker and associated structures and equipment will connect the two main distribution buses.
