Introduction of low and medium voltage XLPE insulated power cable

• 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.

Insulation Screen

•The insulation screen is provided over the insulation by extruding the semiconducting compound concentrically and circularly to minimize the possibility of ionization on the outer surface of the dielectric.

Metallic Screen

•The metallic screen consists of one or more tapes, or a braid, or a concentric layer of wires or a combination of wires and tape(s)applied on the insulated cores. The metallic shielding in multiple conductor cables are in contact with each other and the material is chosen according to different requirements of earth fault current.

Metallic Armor

The armor is a single layer of round wires or double tapes. Material for the armor shall consist of galvanized steel or aluminum. The armor for single core cables for use on AC circuits shall consist of non-magnetic material (eg. aluminum) due to the excessive losses induced by steel armor. When round wire or tape armor is required, in the case of single and multiple conductor cables, it shall be applied on an inner covering, if there is no screening. Where the metal screening and the armor applied over the screening are of different metals, the two shall be separated by an extruded separation sheath. When a tape armor is applied, the thickness of the inner covering shall be reinforced by a bedding tape, If a separating sheath is provided, the additional bedding tape is not necessary.

The tape armor shall be applied helically in two layers so that the outer tape is approximately centered over the gap of the inner tape. The gap between the adjacent turns of each layer of tape shall not exceed 50% of the width of the tape. The standard color of the inner covering and separation sheath shall be black.

Assembly
•The assembly of multiple conductors shall be done by cabling together the required number of conductors with suitable fillers. A suitable binder tape shall be applied over the entire assembly.
