Energized Solution to Uprate 88 kV System
Re-conductor the City Power 88kV system:Uprade to High Temperature ACSS conductorsIncrease individual circuit capacity – 100% targetIncrease individual circuit capacity 100% target.Mechanically harden transmission system, extend life. Enhance system economic performance and end-customer satisfaction
Energized Techniques and Robotic Technology: Safe and economic solution to a complex operation.Shorter project timelineShorter project timelineSecurely holding energized lines/equipment intact during upgradesIncreasing personnel safety Increasing utilization of existing transmission assetsSafely reconductoring, rebuilding and replacing/adding lines and equipment while not taking system out of service
