So we need to have some new type of cable such
that no abstraction (tapping/hooking) can be done
from the cable when it will be used as mainline in
overhead/underground mode. Ultimately our search
ends with the co-axial cable that is mainly used in
telecommunication sector due to low losses of high
frequency electrical signals. In 2016 we came to know
about a cable manufacturing company M/S Universal
who used to manufacture coaxial cable mainly for
telecommunication purposes. The concept was
shared with the vendor and design of 3.5CX 240mm2
unarmored co axial cable was finalized for drawing cable
in overhead mode. We are the first utility in India to use
this coaxial cable in low tension distribution system as
power cable.
