PE Wire Extrusion Lines Explained: From Low-Voltage to High-Speed Cables
Polyethylene (PE) is arguably the most versatile polymer in the wire and cable industry. Its applications range from the rugged, weather-resistant outer jacketing of high-voltage underground cables to the delicate, microscopic insulation of high-frequency LAN cables (Cat 6/7) and 5G coaxial lines. However, for factory managers and process engineers, PE presents a unique set of manufacturing challenges. Unlike PVC, which is relatively forgiving, Polyethylene is a crystalline polymer. It shrinks significantly upon cooling, requires precise temperature management to prevent “melt
