C7® Advanced Conductor - ACCS/TW/C7-TS

Shaped Wire, Aluminum Conductor, Composite Supported

...

Construction:

  1. Core: Stranded continuous carbon fiber thermoset composite core with a protective capping layer.
  2. Stranding:Annealed aluminum (1350-O) trapezoidal shaped strands with 63% conductivity

Applications and Features:

Southwire’s C7-TS conductor is a high-temperature, low-sag (HTLS) advanced conductor designed for overhead transmission and distribution systems where increased capacity and reliability are critical. Its multi-strand carbon fiber composite core delivers near-zero thermal sag, exceptional tensile strength, and structural redundancy to eliminate single-point failures. C7-TS uses fully annealed 1350-O aluminum strands, with trapezoidal strands (TW) for reduced diameter and improved ampacity. Its crew-friendly design allows installation using conventional hardware and familiar techniques. Applications include long-span transmission corridors, thermal uprating of congested lines, and environments requiring superior corrosion resistance.

Continuous operating temperature - 180?°C

Emergency operating temperature - 200?°C

All dimensions are nominal and subject to normal manufacturing tolerances. ? Cable marked with this symbol is a standard stock item.
Notes:
  1. The final design of a TW conductor is contingent upon several factors such as: layer diameter, wire width, and wire thickness. This may result in a slight variation in the number of wires, number of layers, and outside diameter from that shown in the table.
  2. Resistance and ampacity based on an aluminum conductivity of 63'% IACS at 20°C.
  3. Ampacity based on 25°C ambient temperature, 2 ft/s perpendicular wind, 0.5 emissivity, 0.5 absorptivity, 60 Hz, clear atmosphere, sea level, 30° N. latitude, N-S line azimuth, noon on June 10th.

All dimensions are nominal and subject to normal manufacturing tolerances. ? Cable marked with this symbol is a standard stock item.
Notes:
  1. The final design of a TW conductor is contingent upon several factors such as: layer diameter, wire width, and wire thickness. This may result in a slight variation in the number of wires, number of layers, and outside diameter from that shown in the table.
  2. Resistance and ampacity based on an aluminum conductivity of 63'% IACS at 20°C.
  3. Ampacity based on 25°C ambient temperature, 2 ft/s perpendicular wind, 0.5 emissivity, 0.5 absorptivity, 60 Hz, clear atmosphere, sea level, 30° N. latitude, N-S line azimuth, noon on June 10th.
