As per IEC standard the power cable is designed and manufactured with following construction.
 The maximum conductor temperature is ; • Normal operation : 90oC • Short circuit operation : 250oC

1. Conductor
 The conductor consists of annealed copper or hard drawn aluminum stranded wire and becircular stranded, circular compact stranded, circular compressed or segmental compactstranded. The segmental compact stranded construction shall be used for the conductor with area greater than or equal to 800mm2. Specially the enameled copper wire shall be used to reduce the skin & proximity effect of conductor If necessary, semiconducting binder tape may be applied on the conductor.

2. Conductor screen
 The conductor screen consists of an extruded layer of thermosetting semi-conducting compound and shall be continuous and cover the whole surface area of the conductor. The conductor screen shall be firmly bonded to the insulation. The outer surface of the conductor screen shall be circular.

3. Insulation
 The insulation is an extruded cross-linked polyethylene (XLPE). The insulation shall be applied by extrusion and vulcanized to form a compact homogenous body free of microvoids and contaminants. The insulation shall be extruded with conductor screen and insulation screen layer simultaneously. The insulation thickness shall be designed by critical impulse and AC withstand voltage.

4. Insulation screen
 The insulation screen consists of an extruded layer of thermosetting semi-conducting compound and shall be continuous and cover the whole surface area of the insulation. The insulation screen shall be firmly bonded to the insulation.

5. Metal sheath
 The metal sheath consists of copper wire, lead alloy, corrugated aluminum, corrugated copper or smoothed aluminum over insulation screen. The metal sheath shall be designed to meet the required earth fault current.

6. Outer sheath
 The outer sheath consists of an extruded layer of polyethylene or polyvinyl chloride compound.
