XLPE Insulated Overhead Insulated Cable Duplex Service Drop Cable 600 Volts

This duplex service drop cable is composed of an PE or XlPE insulated aluminum conductor and a bare AAAC, or ACSR conductor as neutral or messenger cable twisted together. It also belong to the ABC cable group, usually used from a pole mounted transformer to the service entrance of a structure, or as secondary distribution between poles. It is also used to supply 120 volts aerial service for temporary service at construction sites, outdoor or street lighting. The cable should be limited to 600V phase to phase and not exceed 90˚C.
