Construction 
Concentic strand or cmpressed 1350-H19 conductor, polyethylene or cross linked polyethylene insulation, concentric strand AAC, ACSR, or 6201 alloy nertral messenger. 
2.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. 
3. 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.
