Normally segmental compacted circular conductor has four(4) segments and 2is applied for the cross-section over than 800mm, to prevent the increase of AC resistance caused by skin effect. When the conductor’s cross-section is less than 2630mm, the compacted circular is applied generally.The conductor screen consists of an extruded semi-conducting polyethylene to minimize electrical stresses due to the stranded configuration of the conductor. The semi-conducting material used for conducting tape is sometimes applied as a separator.ConductorConductor screenThe insulation material is extruded cross-linked polyethylene. The conductor screen, the insulation and the insulation screen mentioned to following clause are extruded simultaneously in one process to ensure that the screen and insulation are intimately bonded together and free from all possibilities of voids between layers.The extrusion process is carried out under strictly controlled atmospheric conditions.The thickness of insulation layer is the maximum value figured out from the design of the impulse voltage and A.C. Voltage.The conventional cross-linking process by saturated steam has frequently caused deterioration of the electrical characteristics of the insulation as treeing phenomena arose when put to use for long time. But the new process by N2 gas has enabled to protect the electrical characteristics from deteriorated and to lessen the thickness of the insulation and accordingly the cable’s outer diameter itself.InsulationThe XLPE cable has the construction of a conductor (Copper or Aluminum) insulated with the cross-linked polyethylene and then shielded with metallic screen (Corrugated seam welded Aluminum or Lead sheath or Wire shield) to be covered by PVC or polyethylene for anti-corrosion.Lâi dÉn gåm nhiÒu sîi ®ång mÒm hoÆc nh«m cøng vµ ®îc chia thµnh hai d¹ng lµ lâi nÐn trßn vµ nÐn rÎ qu¹t.Lâi nÐn trßn gåm c¸c sîi quÊn ®ång t©m nÐn chÆt.
