Increasing the Strength Capacity of Existing Overhead Transmission Line Structures

In the context of the energy transition to integrate renewable energy and reduce carbon emissions, electricity networks need to significantly increase in capacity and flexibility. However, in many countries, electricity network operators face strong restrictions on enabling new corridors for the implementation of new overhead transmission and distribution line projects. The solution, in many cases, is to use existing rights of ways to increase power transmission capability through uprating overhead line projects. In most of these cases, reinforcements on the structures are required.

Overhead lines

This Technical Brochure has been created by a Working Group from the CIGRE Overhead lines Study Committee which is one of CIGRE's 16 domains of work.
The field of activities of Study Committee B2 covers design, construction and operation of overhead lines. This includes the mechanical and electrical design of line components (conductors, ground wires, insulators, accessories, supports and their foundations), validation tests, the assessment of the state of line components and elements, maintenance, refurbishment
and life extension as well as upgrading and uprating of existing overhead lines.
