Application

a. Duplex Service Drop
Application: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.
b. Triplex Service Drop
Application: 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 maximum for polyethylene   insulation 90°C maximum for crosslinked insulation.
c. Quadruplex Service Drop.
Used to supply 3 phase power, usually from a polemounted transformer, to the user’s service head where connection to the service entrance cable is made. To be used at voltages of 600 volts or less phase to phase and at  conductor temperatures not to exceed 75°C for polyethylene insulation 90°C maximum for crosslinked polyethylene(XLPE) insulated conductors.



Constructions
Conductor: Round, str
anded and compacted aluminum conductor
Insulation: HDPE, XLPE, PVC
3 power cores consisting of standard aluminium conductors, insulated withXLPE insulation
+ One sheath lighting aluminium conductor with XLPE insulation(optional)
+ One messenger Al-alloy conductor (bare or covered)
The messenger conductor can be of galvanised steel wire also.
The purpose of messenger wire is
A) It acts as load bearing wire.
B) It acts as earth or neutral conductor.
To be used at cotages of 600V phase-to-phase or less and at conductor temperatures not to exceed 75oC for polyethylene insulated conductors or 90oC for crossliked polyethylene(XLPE) insulated conductors.
