PVC Cables ManufacturingHow to StartProcess, Machinery

A cable comprises two or more wires which are bonded, twisted, or braided together to form an assembly. The wires and cables are encapsulated with non-conducting plastic materials, usually, PVC or polyethylene, to impart protection to users and the surrounding environment.

The difference between wrapped and extruded wire

 · Extruded - the wire run through a die with the plastic tube hot-extruded around the wire as a cylinder. Wrapped - the plastic in tape form and wrapped around the wire and seam sealed (this is the WAG). As a general statement about extruded wires this is true, but not about PTFE extrusion.

Which Materials Are Used for Wire Insulation? | EEWeb

The term jacketing tends to be used for high end cables which have a high degree of protection. This means that the insulating outer layer, for example, will not be liable to damage if it were to be knocked into by a moving part. A wire's jacket, therefore, is merely a thicker than usual outer layer of plastic …
