Covered line wire Covered line wire is used primarily for overhead secondary distribution lines.It is not an electrically insulated conductor and is treated as bare conductor when installed. Duplex service drop To supply 120 volt aerial service for temporary service at construction sites, outdoor or street lighting. For service at 600 volts or lower at a conductor temperature of 75 °C maximum. Triplex service drop To supply power from the utility's lines to the consumer's weatherhead. For service at 600 volts or less (phase to phase) at a conductor temperature of 75°Cmaximum for polyethylene insulation or 90°C maximum for cross linked insulation. Quadruplex service drop Used to supply 3 phase power, usually from a pole-mounted transformer, to the user's service head where connection to the service entrance cable is made. To be used at voltage of 600 volts or less phase to phase and at conductor temperature no to exceed 75°C for polyethylene insulated conductor or 90°C for cross linked polyethylene insulated conductors.
Construction Phase conductor: aluminum stranded(AAC) Neutral conductor: aluminum stranded(AAC), aluminum alloy stranded(AAAC), Aluminum conductor steel reinforced(ACSR) Insulation: PVC, XLPE, PE or LDPE
