Description

 

Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductor, Steel-Supported (ACSS/TW) is a concentrically stranded conductor with one or more layers of trapezoidal shaped hard drawn and annealed 1350 aluminum wires on a central core of steel. ACSS/TW can either be designed to have an equal aluminum cross sectional area as that of a standard ACSS which results in a smaller conductor diameter maintaining the same ampacity level but reduced wind loading parameters or with diameter equal to that of a standard ACSS which results in a significantly higher aluminum area, lower conductor resistance and increased current rating.
ACSS/TW is designed to operate continuously at elevated temperatures, it sags less under emergency electrical loadings than ACSR/TW, excellent self-damping properties, and its final sags are not affected by long- term creep of aluminum. ACSS/TW also provides many design possibilities in new line construction: i.e., reduced tower cost, decreased sag, increased self-damping properties, increased operating temperature and improved corrosion resistance. The coating of steel core is selected to suit the environment to which the conductor is exposed and operating temperature of the conductor.

 

 

Service Performance

  1. High tensile strength
  2. Long life
  3. Light in weight
  4. Suitable for high as well as extra high overhead

 

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.

ACSS is a composite concentric-lay stranded conductor. Steel strands form the central core of the conductor with one or more layers of aluminum 1350-0 wire stranded around it. The steel core carries most or all of the mechanical load of the conductor due to the "0" (fully annealed or soft) temper aluminum. Steel core wires are protected from corrosion by galvanizing, aluminizing, or mischmetal alloy coating. Corrosion protection should be selected to suit the environment to which the conductor will be exposed. High strength steel core is also available.

 

 

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%.

 

 

Advantages

  1. Reduced drag characteristics
  2. Excellent self-damping properties
  3. Improved current carrying capacity
  4. Low wind and ice loading parameters
  5. long term creep of aluminum doesnot affect final sag

 

 

Application

 

ACSS is used for overhead distribution and transmission lines. It is designed to operate continuously at elevated temperatures up to 250°C without loss of strength; it sags less under emergency electrical loadings than ACSR; it is self-damping if prestretched during installation; and its final sags are not affected by long term creep of aluminum. The advantages make ACSS especially useful in reconductoring applications requiring increased current with existing tensions and clearances, new line applications where structures can be economized because of reduced conductor sag, new line applications requiring high emergency loadings, and lines where aeolian vibration is a problem.

ACSS/TW is designed for overhead distribution and transmission lines. It is available in equal area and equal diameter
design. The equal area design allows equal ampacity in a smaller diameter conductor when compared with a standard
ACSS conductor. The equal diameter design allowsmore ampacity in an equal diameter conductor when compared
with a standard ACSS conductor.ACSS/TW also provides many design opportunities for new line construction:
i.e., reduced tower cost, decreased sag, increased self- damping properties, increased operating temperature and
improved corrosion resistance.
