Operationalised an extremely versatile set-up, considering all the design options mapped to
geo-technical conditions applicable globally.
Sterlite Technologies Limited (STL)
undertook the challenge of supplying
and installing of Optical Ground
Wires (OPGW) on GETCO’s old
220kV transmission line.
Critical attributes and challenges
The most critical attribute of this
project was that the OPGW was to
be strung on 30 Year old towers
which were built in accordance to
the old BIS standard. This placed
emphasis on the OPGW to be of
a very light and at the same time
this was to be installed in one of
India’s hottest regions, which meant
theconductivity of the OPGW should
be highenough to evacuate the fault even when theconductor was at a
temperature of 50°C andstill not to
exceed 200°C even in the worst
case scenario.
