Percon® 24 Conductor Wire

Download PDF

Percon 24 was developed specifically to meet the requirements of AS22759, AS29606, NEMA WC 67 and ASTM B 624. It replaces cadmium containing PD 135 in these applications.  A truly high performance conductor comprising a minimum strength of 60 ksi (414 MPa), elongation of 8%, electrical conductivity of 90% IACS minimum, excellent flex life and exceptional softening resistance to elevated operating or high fluoropolymer insulating temperatures.

Key Attributes of Percon 24

  • Excellent resistance to corrosive environments.
  • Does not contain any cadmium or environmentally hazardous elements. 

Percon 24 is available bare or plated with silver or nickel, and in light weight constructions.
