4-4 Terrier Aluminum Conductor Duplex Overhead Service Drop Cable

Specification

4-4 Terrier Aluminum Duplex Overhead

Allowable Ampacity for 4-4 Terrier Aluminum Duplex Overhead XLP at 90°C: 115 Amps

Allowable Ampacity for 4-4 Terrier Aluminum Duplex Overhead Poly at 75°C: 90 Amps

Applications:

Duplex aluminium overhead cables have two conductors: one for electrodes, and the other one as a messenger (neutral conductor). This electrical wire, also called duplex overhead aluminum wire, is designed and manufactured for use in 120 V power distribution facilities. It is aerially installed with a maximum operational temperature rating of 75°C. 

Just as the name of the aluminum drop duplex cable suggests, it has aluminium conductors which are insulated with a cross linked polyethylene for chemical and mechanical protection, forming the circular core. A bare messenger wire of this electrical cable is made of aluminum and is longitudinally laid on the conductors.

Construction

Conductors:

Duplex aluminium overhead cables have a concentric strand or compressed 1350-H19 series aluminum conductor.

Messenger:

Duplex overhead aluminum wire has a bare ACSR messenger. Optional constructions include a messenger of AAC or 6201 alloy. 

Insulation:
