Kerite unwraps line of preassembled aerial cables

By Paul Dvorak | May 16, 2014

Kerite, a manufacturer of high quality insulated medium voltage utility and industrial power cable, announced a full line of preassembled aerial cable, ideal for use between substation getaway riser cable and the circuit’s open-wire distribution portion, for express feeder circuits with site limitations, and for installation along space-constrained alleys and backyard boundaries and areas subject to tree-related storm damage.

The conductor, either aluminum or copper, is insulated with Kerite’s time-proven Permashield semiconducting layer and Kerite discharge resistant  EPR system, which is used by Kerite on cable designs up to 138 kV.

The twisted preassembled aerial cable has stood the test of time, with multiple examples of cable connecting a substation to exiting overhead lines lasting well above 50 years without failures. The company’s preassembled aerial cable is composed of three shielded conductor cables banded together plus a messenger wire. The conductor, either aluminum or copper, is insulated with Kerite’s time-proven Permashield semiconducting layer and Kerite discharge resistant  EPR system, which is used by Kerite on cable designs up to 138 kV.

The cable’s insulation shield is a free-stripping design and the metallic shield consists of a 5 mil cupro-nickel or copper tape and/or copper concentric wires. The single conductor cable may also have an overall jacket. The entire twisted assembly is bound to a Copperweld messenger with a copper or optional stainless steel strap that can also be covered with a PVC or PE jacket.

One of several medium-voltage cable designs in the product family, preassembled aerial cables is an excellent choice where many feeders come from a distribution substation and underground construction is not a feasible option. For express feeder circuits with site limitations or where underground construction is cost prohibitive, use of preassembled aerial cable means that several express feeder cables can be safely installed below an open-wire pole-top circuit and then fan out to connect with the open-wire distribution system.

Along alleys and backyard boundaries, where limited clearances between structures and line right-of-way are inadequate for open wire construction, preassembled aerial cable is a safe, effective alternative.  Aerial cables also provide greater service reliability for areas where frequent tree and limb damage occurs during storm activity.
