Triplex Aluminum Service Drop Cable

Product Description:

The product is an assembly of three conductors; 2 phase conductors, and 1 neutral messenger wire.  Conductors are made of concentrically stranded 1350-H19 aluminum alloy.  The neutral messenger wire is available as a 6201-T81 aluminum alloy, all aluminum, and aluminum-clad steel reinforced conductor.  This particular alloy is 99.5% aluminum with added metals such as zinc and copper for enhanced conductivity and strength.  Concentric strands are compressed to reduce the overall diameter of the cable.  This cable can carry up to 600 volts and can function in temperatures up to 90°C.

Applications:

Triplex Aluminum Service Drop Cables are used to run power from utility lines to a residence or building’s weatherhead.  The weatherhead is a vertical pole that protrudes from the roof or from the ground, receiving transmission cables to pass them into the building or underground.

Specifications:

-                In accordance with specifications set forth by the American Society for Testing and Materials, this product meets standards B-230, B-231, and B-232.  These specifications refer to the standards of aluminum concentric-lay-stranded conductors and aluminum conductors with steel reinforcement.  

-                The product meets ASTM standard B-399 for 6201-T81 aluminum alloy conductors for options where neutral messenger wire is 6201-T81 aluminum alloy.   

-                For ACSR neutral messenger wire option, this cable meets ASTM standard B-498 for aluminum-clad steel reinforced conductors.

Construction:

• Conductors

-                The conductors in this cable are composed of 1350-H19 aluminum alloy.  This alloy is 99.5% aluminum with added metals to enhance the conductor’s strength without compromising the aluminum’s corrosion-resistant qualities. 

• Stranding

-                The conductors in this cable are concentrically stranded.  The purpose of concentrically stranded wires is to keep a tight diameter in the cable.

• Insulation

-           This cable is insulated with the option of standard polyethylene or cross-linked polyethylene.  For installation in mild climates where weather is not a major factor, standard polyethylene insulation can be used in wet or dry locations, but should not be used in temperatures exceeding 75°C.  For more arid or tropical regions, cross-linked polyethylene insulation is recommended as it can tolerate temperatures up to 90°C.
