Duplex Overhead Aluminum Cable

Application

Duplex overhead aluminum cable is primarily used to deliver electrical power from an overhead power distribution system to residential buildings. Duplex service drop aluminum cable neutral core is made of concentrically twisted AAC, ACSR, or 6201 aluminum alloy. Mainly used for 120V overhead service applications. Such as street lighting, outdoor lighting, and building temporary services.

Street lighting power supply:

Duplex overhead aluminum cable is commonly used to supply power to residential homes in urban and suburban areas. The cable is installed between the utility pole and the weatherhead or meter base on the building, providing a safe and reliable connection to the electrical grid.

Outdoor lighting:

Duplex overhead aluminum cable can be used to supply power to low-voltage lighting systems in residential and commercial areas. The cable is installed between the transformer and the lighting fixtures, providing a safe and efficient power source for lighting.

Building temporary service power：

Duplex overhead aluminum cable can be used to provide temporary power to construction sites or outdoor events. The cable is installed between a temporary power source and the location where power is needed, providing a temporary power supply until a permanent solution can be installed.

Construction

Stranding the Conductors:

The first step in constructing duplex overhead aluminum cable is stranding the individual conductors together. The conductors are twisted together to form a stranded cable, which is stronger and more flexible than a single solid conductor.

Insulation:

Each individual conductor in the cable is then insulated to prevent leakage and ensure safety. Insulation is usually made of materials such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE) or polyethylene (PE). And the conductor temperature of PVC insulated conductors does not exceed 75 °C, and the conductor temperature of XLPE insulated conductors does not exceed 90 °C.
