1 Types of abc cable:
Duplex Service Drop, Triplex Service Drop, Quadruplex Service Drop
a Duplex Service Drop
Applications: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 maximum.
b Triplex Service Drop
Applications: To supply power from the ulility`s lines to the consumer`s weatherhead. For service at 600 volts or less(phase to phase ) at a conductor temperature of 75 maximum for PE insulation or 90 maximum for XLPE insulation .
c Quadruplex Service Drop
Applications: Used to supply 3 phase power , usually from a pole-mounted transformer to the use`s servic head where connection to the service entance cable is made . To be used at voltages of 600 volts or less phase to phase and at conductor temperature not to exceed 75 for PE insulated conductors or 90 for XLPE insulated conductors.
2 Construction of abc cable
a Phase Conductor construction:The phase conductor is aluminum alloy 1350-H19 hard-drawn, compressed concentric-lay-stranded.
b Neutral Conductor Construction
Cable assemblies are available with the following neutral conductors:
Aluminum conductors, coated-steel reinforced (ACSR), concentric-lay-stranded
Aluminum alloy 1350-H19 hard-drawn, concentric-lay-stranded
Aluminum alloy 6201-T81, concentric-lay-stranded
c Insulation MaterialThe standard insulation on the phase conductor is black low-density crosslinked polyethylene (XLPE)
Alternatively, black linear low-density polyethylene (LLDPE) insulation with a 75°C temperature rating is available upon request.
3 specifications of abc cable
Aluminium stranded conductor(compacted or non- compacted), AAAC messenger core(or ACSR messenger core), XLPE(or HDPE) insulated, Twisted (or Parallel)power cable
ABC cable is a new type of aerial cable for power transmitting, It is extensively used in overhead power transmission line, It improves the safety and reliance of electrified wire netting.
