What is the importance of “concentricity control” in the cable insulation extrusion process?
Why Concentricity Control Matters in Cable Insulation Extrusion Concentricity control in cable insulation extrusion ensures that the conductor rests precisely in the geometric center of the insulating layer (such as XLPE, PVC, or LSZH). Maintaining a high concentricity ratio—ideally above 90%—is critical to preventing electrical and mechanical asymmetry. If the insulation wall thickness becomes uneven […]
