Spacer cables are used by utilities for to improve the reliability and power quality of primary distribution systems, while making them more resistant to storm damage and providing options for areas difficult to engineer with standard bare wire systems.
A manufacturer of overhead and underground power-distribution products says its Spacer Cable is an excellent way to upgrade the distribution infrastructure. Common challenges posed by existing infrastructure includes upgrading circuits in alleyways, road-widening projects, back lot bare-wire services, and reconductoring existing circuits. Manufacturer Hendirx says its Spacer Cable can offer lower project and operations costs, a shortened timeline, and improved reliability. These solutions can satisfy Public Utility Commission requirements for distribution infrastructure improvements.
Spacer Cable’s compact configuration and versatility make it well suited for reconductoring alleyways, where trenching or directional boring for underground circuits can be cost-prohibitive, and required clearances for conventional open wire systems pose significant problems. For road-widening projects, Spacer Cable’s compact configuration and ability to build the spacer cable circuit on either side of the poles can eliminate right-of-way challenges when relocating distribution circuits.
For back lot, bare-wire service in older neighborhoods, the cable addresses the issues associated with potential power quality deterioration due to backyard planting interference with distribution lines, restriction of trimming for aesthetic reasons, and access concerns. The spacers can withstand temporary contact with branches without flickers or outages, which improves aesthetics and access, because tree trimming can be less frequent and less extensive.
For reconductoring distribution lines, Spacer Cable circuits can often be installed under existing energized circuits. The original circuit can be left in service or a double Spacer Cable circuit installed, saving time and money while service continues. All Spacer Cable projects are supported by Hendrix engineering services, which provide technical assistance from design through inspection and preventative maintenance.
