Percon® 28 Conductor Wire

Download PDF

Percon 28 is engineered to have 33% greater minimum break strength with the same electrical conductivity of ASTM B 624 conductors. This alloy allows wire and cable system designers performance improvements in strength, flex life, and the ability to reduce finish cable gauge sizes, saving weight while sustaining the cable break strength of a larger gauge size.

Key Attributes of Percon 28

  • RoHS complaint; does not contain cadmium or any environmentally hazardous elements.
  • Exceptional flex life.
  • Highly resistant to thermal softening from high operating or fluoropolymer insulating temperatures. 
  • Exhibits the nobility inherent in all high copper alloys and is therefore resistant to corrosive environments.

Percon 28 is available in bare, silver or nickel plated and in light weight constructions.
