The XLPE cable has the construction of a conductor (copper or aluminum) insulated with the cross-linked polyethylene, shielded with metallic screen (metallic tapes or wires) and armored with metal tape/wires according to requirements, finally to be covered by extruded PVC (ST2), PE (ST7) or halogen free (ST8) sheath for anti-corrosion.
Conductor
•The conductor consists of annealed copper or aluminum wiresfusually solid conductor of class' stranded conductor of class 2, including non-compacted and compacted methods as well as flexible conductor of class 5 according to IEC60228).The conductor appearance is smooth without any stain, oxidation or mechanical damage.
Conductor Screen
•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 conductor screen has no deleterious effect on the conductor. Semiconducting tape is sometimes applied as a separator.
Insulation
•The insulation material is extruded cross-linked polyethylene.The conductor screen; the insulation and the insulation screen mentioned to the 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 the 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 being deteriorated and to lessen the thickness of the insulation and accordingly the cable's outer diameter itself.
