    Duplex Service Drop Wire

    INQUIRY MESSAGE

    OVERVIEW

    Duplex service drop wire has two conductors and four electrodes. What’s more, two of its electrodes come in a concentric-lay strand. One is an insulated phase electrode, while the remaining electrode is bare and left as a neutral conductor. Triplex aluminum service drop wire is an assembly of three conductors.

    STANDARD

    ASTM B230, B231, B232 and B-399 ,B498,ICEA S-76-474

    Application

    Primarily used for 120 volt overhead service applications such as street lighting,outdoor lighting,and temporary service for construction. To be used at voltage of 600 volts phase-to-phase or less and at conductor temperatures not to exceed 75°C for polyethylene insulated conductors or 90°C for crosslinked polyethylene(XLPE) insulated conductors.

    Construction

    The phase conductors are concentrically stranded compressed 1350-H19 aluminum and insulated polyethylene or crosslinked polyethylene(XLPE), The neutral messengers are concentrically stranded AAC, ACSR, or 6201 aluminum alloy.
