1. Construction
ACSS/TW, a nonhomogeneous conductor, is a trapezoidal shaped wire compact concentriclay- stranded conductor made from aluminum 1350-O wires and round, coated steel core wire(s). ACSS/TW conductors withequal area or equal diameter as compared to ACSS conductors are available for overhead lines. Steel wires are coated with Class A coating of zinc – 5% aluminum mischmetal alloy. Other Classes of coatings are also available for additional protection from corrosion. Standard, High, Extra and Ultra High Strength steel are also available.

2. Features
ACSS conductors are preferred over ACSR conductors for specific transmission line
Applications:
With zinc – 5% aluminum mischmetal alloy coating on steel wires, ACSS conductors can be operated
Up to 250 ° C.
ACSS conductors carry more current than ACSR conductors due to:
— Minimum average conductivity of 63% IACS for 1350-O aluminum wires vs. An average conductivity of 61.2% for 1350-H19 aluminum wires in ACSR.
— ACSS conductors can be operated up to 250 ° C vs. The maximum operating temperature for an ACSR conductor does not exceed 100 ° C.
ACSS conductors are prone to resist the effects of aeolian vibration due to very little or no mechanical load on the annealed aluminum wires.
Long term creep is not a factor when designing with ACSS conductors. In addition, use of ACSS/TW with the equal area design allows equal ampacity in a conductor with approximately 10% smaller diameter over a standard ACSS with same area. This smaller diameter of equal area ACSS/TW conductors helps reduce the effects of ice and wind loading on the conductor.
Alternatively, use of ACSS/TW with equal diameter design provides a conductor in which the aluminum area is increased by approximately 20% – 25% over a standard ACSS with same diameter. This increase
In the cross-sectional area of the conductor reduces its ac resistance by about 15% – 20% and thus, increases its current carrying capacity by about 10%.
