TransPowr® A1 (ASC) Bare Overhead Conductor (Canada)

Bare all-aluminum 1350 (A1 or ASC) are concentric-lay-stranded conductors consisting of one or more layers of wire wrapped helically around a straight round central wire. Each successive layer has six wires more than the layer immediately beneath. Greater flexibility is provided by increasing the number of strands for a specific cross-sectional area. A1 or ASC conductors are manufactured in accordance with the requirements of the latest applicable issue of CAN/CSA C61089. A1 or ASC (Aluminum Stranded Conductor) conductors are CSA reference terms. The Canadian constructions are similar in design (strand component size and configuration) to the ASTM B231 specifications. Differences lie in the methods used to calculate the rated strength and dc resistance values. The commonly used strandings are 7, 19, 37, 61 and 91. The sizes and strandings listed on the following pages are common examples used in overhead lines. Metric (mm2) sizes are also available.
