Fil et câble
The wire and cable manufacturing domain is responsible for fabricating electrical, data transmission, and structural conductors, primarily composed of copper, aluminium, and specialized alloys. These products constitute fundamental components for diverse applications including electrical power distribution, telecommunications networks, automotive systems, aerospace platforms, electronic devices, and civil construction projects. A core emphasis is placed upon optimizing electrical conductivity, mechanical flexibility, structural durability, and, crucially, maintaining insulation integrity and superior surface quality.
The fabrication processes within this industry necessitate high-speed, continuous production methodologies coupled with stringent control over both physical and electrical properties. Consequently, induction heating presents an optimal solution for numerous critical stages within this manufacturing workflow.
How Induction Heating Supports Wire & Cable Manufacturing
Induction heating provides precise, localized, and energy-efficient heat, especially useful for inline and high-speed applications. It’s used for annealing, preheating, drying, curing, and coating preparation, enabling better material properties and cleaner processing.
