Design and construction of Transmission line

Transmission Line Design involves route selection, reconnaissance survey, earth resistivity test, preliminary survey etc.
SELECTION OF ROUTE
The route of a transmission line is decided from the following main considerations.
a) Shortest length, hence least capital cost.
b) Ease during construction and ease in maintenance of the line (route near roads for
easy approach & accessibility).
c) Requirement of future loads (sub stations) near the proposed route so that the line can
be easily connected.
d) Required separation distance from parallel communication lines (P&T, Railways,
etc.) for meeting the conditions of induced voltage for obtaining PTCC approval.
e) Avoiding of forest areas as well as wild life sanctuaries.
f) Cost of securing and clearing right of way (ROW).
g) Maintaining statutory distances from Airports /Helipads.
RECONNAISSANCE SURVEY
It is carried out for deciding upon the most economical line route and the most economical location of towers in view of the high cost per location.
PRELIMINARY SURVEY
- FIXING OF ROUTE ALIGNMENT
- CROSSING OF POWER LINES
- CROSSING OF THE TELECOMMUNICATION LINES
- CROSSING OF RAILWAY TRACKS
- CROSSING OF ROADS
- RIGHT OF WAY
- MAINTAINING STATUTORY CLEARANCES
- APPROVAL OF FOREST DEPARTMENT
- ROUTE MARKING
- MEASUREMENT OF EARTH RESISTIVITY
- PLOTTING OF THE ROUTE ON THE MAP
- APPROVAL OF THE LINE ROUTE
We have carried out studies, detailed engineering, manufactured & supplied several tones of transmission structures.
