Middle Voltage Aluminum Service Drop Cable AAC Conductor Material

1. Application of Service Drop Cable :
Aerial Bundle Conductor (ABC cable) is a very innovative concept for overhead power distribution as compared to the conventional bare conductor overhead distribution system. It provides higher level of safety and reliability, lower power losses and ultimate system economy by reducing installation, maintenance and operative cost. This system is ideal for rural distribution and it is especially perfect for installation in difficult terrains such as hilly areas, forest areas, coastal areas etc. ABC is also considered to be ideal for power distribution in congested urban areas with narrow lanes and by-lanes. In developing urban complex, ABC cable is the first choice because of its flexibility for re-routing as demanded by changes in urban development plan.

2. Type of Service Drop Cable:

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.

3 . Construction

Phase conductors are concentrically stranded EC Grade aluminum wires, insulated with either black weather resistant cross linked polyethylene (XLPE) or polyethylene (PE). The conductor insulation is marked with longitudinal ridges for phase identification.

Neutral messengers are concentrically stranded AAC or 6201 Alloy or ACSR. Neutral messenger can either be bare or insulated, depending on ABC design.
