High-voltage power cables
The cables used for high-voltage power distribution require termination
and installation expertise beyond the normal experience contracting
electrician.0 4.
However, much simpler use and terminate than cable. spe-
cial terminations are required, the cable may terminated through a
grommet into knock out box terminated through simple compres-
sion gland. The conduct-
ors are then screened, wrapping aluminium tape around the insu-
lated conductors, that is, between the insulated conductors and the outer
sheath. The alumin-
ium conductors carry the current and the steel core provides the tensile
strength required suspend the cable between pylons. The regulations covering high-voltage distribution are beyond
the scope the IEE regulations for electrical installations.
High-voltage overhead cables
Suspended from cable towers pylons, overhead cables must light,
flexible and strong.0mm.
The sheath circular and made robust thermoplastic low smoke, zero
halogen material. This aluminium tape screen applied metal side down and con-
tact with the bare CPC.
The cable fire resistant cable, primarily intended for use fire alarms
and emergency lighting installations may embedded plaster.
The cable constructed stranded aluminium conductors formed
around core steel stranded conductors (see Fig.

core, red, yellow and blue and four core, black, red, yellow and blue. The cable not
insulated since placed out reach and insulation would only add to
the weight the cable. Operating at
