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 volt or less (phase to phase)

at a conductor temperature of 75°C maximumfor polyethylene  insulation 90°C maximum for crosslinked insulation.

Quadruplex 

Service Drop

 Used to supply 3 phase power, usually from a polemounted transformer, to the user'sservice head where connection to

the service entrance cable is made. To be used at voltages of 600volts or less phase to phase and at  conductor temperatures not to exceed 75°C for polyethyleneinsulation 90°C maximum for crosslinked polyethylene(XLPE) insulated conductors.
