1926.9-42/19 TYPE 13 ACSR/TW/GA2 CUMBERLAND 3150 FT

Southwire #: 61708601

Used for bare overhead transmission, primary and secondary distribution. Two design offerings: Equal Area or Equal Diameter when compared to standard round ACSR. Equal area designs allow comparable ampacity in a smaller diameter when compared to a standard round ACSR. Equal Diameter designs allow more ampacity and strength in an equal diameter conductor when compared to a standard round ACSR
