The structure of XLPE high voltage cable insulation is composed of an insulative layer and semiconductive layers. The semiconductiv material is a blend of polyolefin elastomer material and carbon black, which is used for the boundary layer of the electric field of the cable insulation layer. Since the physical properties of the semiconductive layer and the insulative layer are similar, they are also co-extruded in the production process, there is no air gap at the interface. The electric field in the insulation from the high potential of the core shielding layer to the low potential of the external shielding layer is perfect in XLPE insulation layer, which can withstand higher operating voltage and service life. According to the principle of higher electric field strength at the small curvature radius of the equipotential surface, the semi-conductive layer faces the insulation. If there are protrusions on the interface, it will cause the increase of the electric field strength to damage the insulation. Therefore for, the production of semi-conductive materials and cable insulation systems, it is required to limit the number and size of the protrusions on the surface of the semi-conductive layer strictly. The specific implementation of the quality control system is to control the number and size of the protrusions on the surface of the semiconductive material strip.
