Power transmission line design

Power transmission line design

We have been designing transmission lines for over 30 years.

Over 7000 km of power transmission lines projects

Transmission lines are the means whereby the electrical energy is transported from the source of generation to the places of use.
The design of overhead electrical transmission lines involves contributions of many disciplines. Movement of electric power requires supporting structures, conductors to carry the current, insulators to provide safe distance of charged conductors from supporting structures and appropriate connecting hardware all meeting standards for safety and reliability.
The lines must be capable of operating reliably in all the environmental conditions that they experience and should have as low an impact as possible on these environments.

We care about every detail of the transmission line design

The reliability of the transmission line is determined not only by the quality of the equipment but also by a consistent compliance with relevant standards and norms, in particular IEC standards, national standards and norms as well as internal regulations. Security and safety of the electrical power supply imply strict adherence to the conditions specified in standards, norms and regulations concerning the prevention of accidents.
Power transmission lines are operated with restrictions imposed by legal requirements, technical standards, political issues, financial constraints and social, political and environmental parameters.
