TransPowr® Compact (Smooth Body) ASC Bare Overhead Conductor (Canada)
Smooth Body bare all-aluminum 1350 conductors (A1 or ASC) are compact, concentric-lay-stranded wires made up of one or more layers of wire that are helically wrapped around a straight, round central wire. These conductors are manufactured in accordance with the latest applicable CSA C49.5 standards.
A1 and ASC are reference terms used for Aluminum-Stranded Conductors in Canadian standards. The design of Canadian constructions is similar to that specified in ASTM B400, including the strand component sizes and configurations. However, there are differences in the methods used to calculate the rated strength and DC resistance values.
The commonly used strandings are 7, 18, and 19. The sizes and strandings listed on the following pages are typical examples used in overhead lines. Additionally, metric sizes (mm²) are also available.
Class AA strandings are used for bare overhead lines. The lay of the outer layer is right-handed, and it is reversed in successive layers. The temper is full hard drawn (H19).
Class A strandings are primarily used for overhead conductors to be covered with weather-resistant materials. Greater flexibility is provided than in Class AA. The direction of lay of the outer layers is right-hand and is reversed in successive layers. The temper is full hard drawn (H19).
Features and Benefits
The conductors have a smaller diameter, resulting in lower resistance to ice loads and wind. They are lighter than ACSR (Aluminum Conductor Steel Reinforced), resulting in lower unit-length costs, easier handling during installation, and simpler fittings. Additionally, all-aluminum conductors offer high corrosion resistance due to their uniform construction.
