Conductor
The conductor consists of annealed copper or hard aluminum
stranded wires and classified into three (3) major types of
concentric, compacted circular and segmental compacted
circular.
The concentric is the wires wounded up concentrically, the
compacted circular conductor consists of segments wounded
up and then compacted. Normally the segmental compacted
circular conductor has four (4) segments and is applied for the
cross-section over than 800mm2, to prevent the increase of
A.C. resistance caused by skin effect. When the conductors
cross-section is less than 630mm2, the compacted circular is
applied generally.
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. Semi-conducting tape is sometimes applied as a
separator.
Insulation Screen
The insulation screen is provided over the insulation by
extruding the semi-conducting compound concentrically and
circularly to minimize the possibility of ionization on the outer
surface of the dielectric.
Metallic Screen
The metallic screen consists of the wire shield, the corrugated
aluminum sheath or the lead sheath. The corrugated aluminum
sheath and the lead sheath is also adopted where the surface
of duct is poor and where moisture is high.
Outer Sheath
To protect the metallic sheath from electrical or chemical
corrosion, it is covered by PE or PVC.
