Transmission Line Design

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.

Shortest length, hence least capital cost.
Ease during construction and ease in maintenance of the line (route near roads for easy approach & accessibility).
Requirement of future loads (sub stations) near the proposed route so that the line can be easily connected.
Required separation distance from parallel communication lines (P&T, Railways, etc.) for meeting the conditions of induced voltage for obtaining PTCC approval.
Avoiding of forest areas as well as wild life sanctuaries.
Cost of securing and clearing right of way (ROW).
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

Supreme provide the full range of services related to the planning, design and construction management of HV and EHV power transmission systems, as well as with medium and low voltage distribution networks. The projects cover the full range of activities, including studies, engineering, manufacturing, supply, works supervision and commissioning of the completed installation. Training in these fields as well as in network maintenance and operations is also available.

We have carried out studies, detailed engineering, manufactured & supplied several thousand tones of transmission structures up to 400 kV.
