Overview
Percon 28 is engineered to have 33% greater minimum break strength with the same electrical conductivity of ASTM B 624 conductors. This alloy provides wire and cable system designers with 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.
As with all Percon products, Percon 28 is RoHS complaint, thus free of cadmium or any environmentally hazardous elements. It has exceptional flex life and is highly resistant to thermal softening from high operating or fluoropolymer insulating temperatures
Percon 28 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.
Percon 28 is classified in AS29606 as the “Extra High-Strength” alloy class.
