ACSSTW Conductor

ACSS/TW, a non homogeneous conductor, is a trapezoidal shaped wire compact concentrically-stranded conductor made from annealed aluminum 1350-O wires and round, coated steel core wire(s). ACSS/TW conductors with equal area or equal diameter as compared to ACSS conductors are available for overhead lines. Steel core wires are protected from corrosion by selecting an appropriate coating of the wire like galvanizing, mischmetal alloy coating or aluminum clad. The type of coating is selected to suit the environment to which the conductor is exposed and operating temperature of the conductor. Standard, High, Extra and Ultra High Strength steel are also available.


ACSS/TW conductors have the following features:

  • Work  at High Temperature upto 250°C  without any loss of Strength 
  • Better self damping property
  • Low sag at high temperature
  • Improved current carrying capacity

Applicable Specification

ACSS/TW conductors are manufactured by Gupta Power in accordance to ASTM B 857 & Other Standard
