CYMCAP (CYME Cable Ampacity Program) is a dedicated simulation tool developed jointly by Ontario Hydro Technologies, McMaster University, and CYME International. The software is built specifically to address the thermal rating of power cables.

Analyzing soil conditions and heat dissipation.

The comprehensive user manual (often over 300 pages) is generally provided to licensed users within the software installation. You can typically find it by navigating to the menu inside the CYMCAP application.

For over 30 years, CYMCAP has been the trusted standard for cable engineers, and as the software evolves—now with advanced 3D and tunnel modeling features—the accompanying documentation becomes ever more critical. Whether you are a student, a practicing engineer, or a project manager, securing this manual is the first step toward ensuring your cable installations are safe, reliable, and optimized for the demands of a modern power grid.
