Specification

2-2 Chow Aluminum Duplex Overhead

Allowable Ampacity for 2-2 Chow Aluminum Duplex Overhead XLP at 90°C: 150 Amps

Allowable Ampacity for 2-2 Chow Aluminum Duplex Overhead Poly at 75°C: 120 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.
