                                         Information @ a Glance
General
  • Aluminum is a silvery white and ductile member of the poor metal group of chemical elements.
  • Aluminum conductors provide an economical alternative to copper and have been used for many years in various types of insulated wire and cable.
  • Aluminum conductors used today in building wire and service cables are more than likely manufactured from an aluminum alloy known as an ACM alloy.

Technology

  • The aluminum industry has evolved over the past 100 years from the limited production of alloys and products to the high-volume manufacture of a wide variety of products. Today’s U.S. aluminum production includes roughly 5.6 million tonnes of flat-rolled products, 1.7 million tonnes of extrusions and tube, and 2.4 million tonnes of ingot/castings.
  • The conventional method for splicing high voltage conductors uses a hydraulic press to form a compression joint that connects the two ends of a conductor.
  • The first technology being tested at Powerline Conductor Accelerated Testing (PCAT) is an aluminum conductor composite-reinforced (ACCR) cable, which is an advanced conductor developed by 3M Corporation.

Application

  • Aluminum is used widely for high-voltage switchyard bus, as tubular aluminum conductors provide a very favorable combination of mechanical and electrical characteristics.
  • Aluminum Conductors has excellent dielectric insulation with very thin film thickness and high thermal conductivity without an interleaved insulation, impeding heat transfer.

Market

  • The market for aluminum transmission cable wire grow as the country expands power transmission capabilities.

  • There are additional markets for aluminum conductors in building wire, winding wire and CATV coaxial cable. All three of these markets are thought to account for slightly less than 50,000 tonnes of aluminum use each, annually.  

Report

  • Aluminum conductor has been used by various other groups in magnet construction but this has been the exception rather than the rule.

  • ACSS uses a fully annealed aluminum conductor around a steel core. The steel core provides the entire conductor support. The aluminum strands are “dead soft”, thus the conductor can be operated in excess of 2000C without loss of strength.
