Triplex Service Drop Cable

Triplex wire is commonly used for overhead, single phase service and contains three individual wires twisted around each other. The two insulated conductors are called the "hot" legs of the service while the bare (uninsulated) wire is the neutral wire of the service. As mentioned above, this triplexed cable is suited for use as drop cable from a pole mounted transformer to the service entrance of a structure, or as secondary distribution between poles.

* Ampacity based on 40˚C ambient temperature, crosswind at 2ft/s, and no sun.
