The Hendrix Spacer Cable equipment is resistant to shock, impact, and rifle fire, and can be installed with hot-line tools. Individual cables used in the system contain a 3-layer covering, that withstands temporary contact with tree branches and other vegetation, thus reducing outages and improving power quality.
A manufacturer of overhead and underground power distribution products announces the availability of Hendrix Spacer Cable Systems, a space-saving product for substations. The spacer cable reduces right-of-way requirements at substation exits, allows more efficient use of limited space in substations, and provides increased reliability on the critical feeder circuits at substation exits.
A spacer-cable system consists of a messenger cable that supports the structure, polyethylene spacers to hold the cable across spans, and covered conductor cable. The messenger cable is the support member for the structure, serving as both system neutral and lightning shield. After being installed and attached to the messenger, the spacers support, separate, and clamp the phase conductors.
Using bare wire at substations can cause significant issues with electrical clearance and reliability. Spacer cables allow for multiple circuits on each pole, reducing right-of-way requirements at substation exits and along distribution lines that required multiple circuits. Furthermore, over or under-building spacer cables in substation exits can greatly reduce the cost of adding capacity.
In addition to saving space, the cable covering and the mechanical strength of spacer cable equipment provides increased reliability on the critical feeder circuits at substation exits.
The spacers have excellent weather washing characteristics. Their long leakage distance resists flashovers, their close phase spacing minimizes voltage drop, and their design provides high short-circuit strength.
