55A Series Aerospace XL-ETFE Insulated Wires and Cables
Product Introduction:
As a high-temperature installation wire used in aerospace environments, the 55A series wires and cables adopt a new type of material—irradiation cross-linked ethylene-tetrafluoroethylene (XETFE)—as insulation. They feature outstanding advantages such as light weight, radiation resistance, and excellent electrical and mechanical properties. With a long-term operating temperature range of -100℃ to +200℃, they maintain superior resistance to chemical reagents and adaptability to space environments within this range.
Reference Standards:
MIL-W-22759/32~35,MIL-W-2275/46
This product is a perfect replacement for Raychem’s 55A series cables.
