Application
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, outdoorr or street lighting. For service at 600 volts or lower ar a conductor temperature of celsius 75 maximum.

Triplex service drop
To supply power from the utility"s lines to the consumer"s weatherhead. For service at 600 volts or less (pahse to phase) at a conductor temperature of celsius 75 maximum for polyethylene insulation or celsius 90 maximum for crosslinked 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 celsius 75 for polyethylene insulated conductor or celsius 90 for crosslinked polyethylene insulated conductors.

Construction
Concentric strand or compressed 1350-H19 oncductor, polyethylene or crosslinked polyethylene insulation, concentric strand AAC, ACSR, or 6201 alloy neutral messenger.
