Duplex Aluminum Service Drop Cable

Product Description:

This aluminum cable comes with two concentric-lay stranded conductors, one insulated phase conductor, and one bare neutral messenger.  Aluminum components of the cable are aluminum 1350-H19, an alloy that maximizes the conductivity of aluminum while adding strength for mechanical efficiency.  The phase conductor is insulated with a standard polyethylene or crosslinked polyethylene jacket to protect the conductor from excessive dryness, moisture, and sunlight.  The cable can handle up to 600 volts at temperatures between 75° and 90°C depending on the insulation type.

Applications:

The Duplex Aluminum Service Drop Cable can be used as an overhead line, most commonly used for lighting.  This cable is often used for street lighting and outdoor lighting situations.  The cable can be used in construction areas for temporary service to power lightning and machinery as well.  The option of standard polyethylene or crosslinked polyethylene insulation depends on the climate and weather conditions where the cable will be used.  The standard polyethylene insulation can handle temperatures up to 75°C.  This option is preferred in mild climatic regions where high heat is not an issue.  Crosslinked polyethylene can handle temperatures up to 90°C and is preferred in more harsh regions such as desert or tropical regions. 

Specifications:

• In accordance with the American Society for Testing and Materials, the aluminum components in this product meet B-230 and B-231 standards for 1350-H19 standards.  These standards ensure the proper amount of aluminum (99.5%) is included in the conductor’s metal composition. 
• This product meets ASTM specifications standard B-232 for reinforced overhead conductors.
• The round stranded aluminum wires are compressed to reduce the diameter of the cable.  This cable meets ASTM standard B-901 for compressed stranded conductors using single input wire.

Construction:

• Conductors

–                This cable consists of two aluminum alloy cables; a phase conductor and a neutral conductor.  The electrical components of this cable are aluminum 1350-H19 aluminum alloy.  This alloy is 99.5% aluminum with added metals to enhance strength and conductivity.   The neutral conductor serves as a ground line to ensure steady conductivity in the phase conductor.

• Stranding

–           The stranding on the two conductors on this cable are concentric-lay stranded.  The conductors are also compressed to reduce gaps between wires and to reduce the overall diameter of the cable.

• Insulation

–           There are two options of insulation available; standard polyethylene and crosslinked polyethylene.  The standard option is preferred in mild climates where heat will not be a major factor.  The crosslinked polyethylene option is preferred in hot, humid, or arid climates.
