TransPowr® Compact (Smooth Body) ACSR Bare Overhead Conductor (Canada)

TransPowr® Compact (Smooth Body) ACSR Bare Overhead Conductor (Canada)
Product description

Smooth Body ACSR is a composite compactlay-stranded conductor. The conductors are manufactured in accordance with the latest applicable issues of CSA C49.2. 

The steel strands form the central core of the conductor, around which is stranded a layer of aluminum 1350-H19 wires. The sizes listed on the following pages are common examples used in overhead lines. Metric (mm2 ) sizes are also available. 

The Canadian Smooth Body ACSR conductors are supplied in various tensile strength configurations, designated as Type 100, Type 150, and Type 200. For each conductor gauge size, the regular product is known as Type 100. Type 150 designates a conductor design with the same AWG size, but with 150% the rated strength of the Type 100. Type 200 follows accordingly, with twice the rated strength of the Type 100.

 

Features and Benefits

ACSR conductors are recognized for their record of economy, dependability and favorable strength/ weight ratio. ACSR conductors combine the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel. In line design, this can provide higher tensions, less sag, and longer span lengths than obtainable with most other types of overhead conductors. 

The steel strands are added as mechanical reinforcements. The cross-sections above illustrate some common strandings. The steel core wires are protected from corrosion by galvanizing. The standard Class A zinc coating is usually adequate for ordinary environments. For greater protection, Class B and C galvanized coatings may be specified. 

The product is available with conductor corrosion-resistant inhibitor treatment applied to the central steel component. 

 

Applications

Compact Aluminum Conductors, Steel-Reinforced (ACSR) are used for overhead distribution and transmission lines. The Type 100 compact ASCR conductor style is also used as the support conductor in the CSA Neutral Supported Service Entrance Cable as referenced in the CSA C22.2 No. 129 specification.
