ACSS/TW
Used as bare overhead transmission cable and as primary and secondary distribution cable. It is designed to continuously operate up to 250°C without losing strength.
Construction
What it's built from
- Construction
- Aluminum alloy 1350 wires, concentrically stranded around a steel core with one or more layers of 63% minimum average conductivity aluminum 1350-O wire stranded around it.
- Mechanical load
- The steel core carries most or the entire mechanical load of the conductor due to the fully annealed or soft temper aluminum.
- Core protection
- The steel core wires are protected from corrosion by a zinc-5% aluminum-mischmetal-alloy coating.
- Sizing
- Diameter or Area Equal to Standard ACSR Sizes.
