What is the “semi-conductive layer of a cable”?
The semi-conductive layer of a cable (also known as the semicon layer or screen) is a critical electrical field-smoothing barrier placed between the metallic components and the primary insulation. In medium- to extra-high-voltage cables, there are two distinct layers applied via a three-layer co-extrusion process: the Conductor Screen (inner semicon) and the Insulation Screen (outer […]
