To supply power from the utilitys lines to the consumers weatherhead.For service at 600 volts or less(phase to phase) at a conductor temperature of 75oC maximum for polyethylene insulation or 90 oC maximum for crosslinked insulation.

Construcrtion

1.stranded aluminium conductor
2.PE or XLPE insulation
3.ACSR, AAAC,Galvanised steel wire Messenger wire
3 power cores consisting of standard aluminium conductors, insulated with XLPE insulation
+ One sheath lighting aluminium conductor with XLPE insulation(optional)
+ One messenger Al-alloy conductor (bare or covered)
The purpose of messenger wire is
A) It acts as load bearing wire.
B) It acts as earth or neutral conductor

Technical Data:
Maksimum operating temperature 90 degree
Maximum short-circuit temperature 250 degree.Service drop( ABC cables) are especially used at areas where the cost of underground networks is expensive and also for electrification of rural areas like village.

TECHNICAL PARAMETERS:

Note:
(1)Designated sizes are: ACSR 6/1 diameter equivalent and AAC with equivalent resistivity per ASTM B-399 for 6201.
(2)Conductor temperature of 90°C for XLPE, 75°C for PE; ambient temperatures of 40°C; emissivity 0.9; 2ft./sec/wind in sun.

Classification

1. Duplex Service Drop

Primary used for 120 volt overhead service application such as street lighting, outdoor lighting, and temporay service for construction. To be used at voltages of 600 volts phase to phase or less and at conductor temperature not to exceed 75degee for polyethylene insulated conductor or 90 degree for crosslinked polyethylene (XLPE)insulated conductors.

2.Triplex Service Drop

Used to supply power, usually from a pole-mounted transformer to the user's service head where the connections to the service entrance cable is made. To be used at voltage of 600 volts phase to phase or less and at conductor temperature not to exceed 75degee for polyethylene insulated conductor or 90 degree for crosslinked polyethylene (XLPE)insulated conductors.

3. Quadruplex Service Drop

Used to supply 3 phase power, usually from a pole-mounted transformer to the user's service head where the connections to the service entrance cable is made. To be used at voltage of 600 volts phase to phase or less and at conductor temperature not to exceed 75degee for polyethylene insulated conductor or 90 degree for crosslinked polyethylene (XLPE)insulated conductors.

Package:In coils, wooden drums, steel drums or steel-wooden drums.
