Hendrix Wire & Cable (www.hendrix-wc.com), a provider of high-quality overhead and underground power distribution products, announces the completion of a project for Clark Energy Cooperative, a nonprofit electric utility headquartered in Winchester, Kentucky, U.S.
Clark Energy needed to add a circuit to an existing double-circuit bare-wire system out of a substation in Stanton, Kentucky. The project spanned 4416 circuit ft (1346 circuit m) and was originally conceived to be a conventional triple bare-wire circuit. Hendrix worked with Clark Energy and designed a spacer cable system that could be built under the existing double-circuit bare-wire system. After detailed engineering analysis, Clark elected to go with the Spacer Cable alternative.
Todd Peyton, manager of engineering at Clark Energy commented that the “Stanton Project's actual cost, including make-ready — which involves moving transformers, installing anchors, etc. — was $19.58/ft. This is less than 30% the cost I estimated to rebuild the existing double-circuit with conventional triple-circuit wire.”
Spacer Cable has been used by utilities for many years to improve the reliability and power quality of primary distribution systems while making them more resistant to storm damage. The cable design, system strength and compact configuration also can serve to address other concerns that can crop up on a utilities distribution system. The compact configuration and reduced clearance requirements allow for multiple circuits to be installed on a single pole, thus combating right-of-way problems and saving money by reducing the number of poles required. Over- or under-building spacer cable systems in substation exits, alleyways and feeder circuits can reduce the cost of adding capacity.
Aerial Cable & Systems is one of four operating divisions of Hendrix Wire & Cable, a provider of high-quality overhead and underground power distribution products located in Milford, New Hampshire, U.S. The divisions benchmark product, Spacer Cable, formed the foundation of the company in 1951, solving local utilities' reliability problems, reducing weather-related outages and providing options for areas difficult to engineer with standard bare-wire systems. Today, Hendrix Spacer Cable is available at 15 kV through 69 kV.
