Percon^® 24 Conductor Wire

Conductor Wire

Percon 24 was developed specifically to meet the requirements of AS22759, AS29606, NEMA WC 67, ASTM B 624, and MIL-DTL-25038. 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 6%, 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.
