Transmission lines - the highway for our electricity - transport power to consumers who are often far from major cities. These distinctive structures ensure that power is readily available and accessible wherever it is needed.
We have a highly skilled, experienced team
For over 20 years, CIMA+ has been honing its expertise in the field of overhead and underground transmission line design, becoming a leader in the industry.
Our clients can count on our experts at every stage of a transmission line project, from the development of the design criteria to the commissioning of a line. Our team has extensive experience in transmission line design, refurbishing and upgrading.
CIMA+ was one of the first engineering consulting firms to adopt the PLS-CADD power line systems software, and we are recognized for our overhead transmission line modelling. Our highly qualified and experienced professionals can design and detail towers and foundations, and size overhead cables.
Our experts can decide the best route and technology for your cables and equipment based on geotechnical and geomorphology data. We can also size underground cable conductors to ensure a long, maintenance-free lifespan for the new underground lines. In addition, our team can add special features to projects, such as Distributed Temperature Sensing (DTS) systems integrated into the insulation of each cable.
