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 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

  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.
