Transmission line engineering

Route planning, tower engineering and conductor design for overhead transmission lines up to 765 kV.

The engineering challenge

A clear basis.
A coordinated design.

A transmission line brings route conditions, conductor behaviour, tower loading and foundations into one design. Degi Trans supports new lines, special crossings and the review of existing infrastructure, from survey and line layout through detailed engineering and project monitoring.

Where we contribute

Support through the details.

The scope is agreed around your project stage and available inputs.

Route survey and line layout

Route surveys, profiling and tower spotting in PLS-CADD, with attention to terrain, clearances and crossing requirements.

Towers and special crossings

Transmission tower design up to 765 kV, including river and rail crossings and crossings above or below other power lines. Tower and foundation requirements are coordinated around the site.

Conductors, sag and stringing

Conductor design to suit the project, sag-template curves and stringing charts for conductors and ground wires. Sag templates can be prepared as softcopy or on acrylic sheet where required.

Upgrades and power evacuation

Advice on upgrading and uprating transmission lines, alongside the engineering of power evacuation schemes for the project’s requirements.

Inspection and project monitoring

Third-party inspection of tower parts and accessories, design checking and transmission line project monitoring within the agreed engagement.

A defined scope of work

From inputs
to useful outputs.

We confirm the required calculations, drawings and review support at the start of each engagement.

Typical areas of delivery

Route profiles and PLS-CADD tower spotting data
Conductor design inputs, sag templates and stringing charts
Tower calculations, structural drawings and foundation coordination
Fabrication drawings, shop sketches and bills of materials
Power evacuation and line upgrade recommendations
Inspection findings and project monitoring reports
