Substation expansions can become extremely complicated when space is limited. That's when use of high-voltage underground cable comes into its own as a viable option. What makes the option even more favorable is a turnkey approach, in which the high-voltage underground cable provider provides the cable, terminations and testing and documentation. At a recent substation expansion project located near Buffalo, NY, USA, where expansion of a substation yard and extension of an overhead 115 kV bus was impracticable and relocating facilities within the substation was impractical, Seymour, CT, USA-based Kerite Company provided turnkey underground cable installation services that allowed new capacitor banks to be installed and energized in a reasonable amount of time and for reasonable cost.
