CYMCAP Rev 7.1

CYMCAP Rev by CYME is a specialized engineering application for calculating the ampacity and thermal performance of power cable systems. It helps utilities, consultants, and industrial facilities design, verify, and optimize cable installations under steady-state and transient conditions. Using industry-accepted methods such as IEC 60287, IEC 60853, IEEE 835, and Neher–McGrath, the software evaluates current-carrying capacity, conductor and insulation temperatures, and mutual heating among multiple circuits.

Key capabilities include:

• Support for common installation types: directly buried cables, duct banks, pipes, trays, and tunnels.
• Detailed thermal modeling of soils and backfills, including layered media, thermal resistivity, moisture migration, and seasonal effects.
• Steady-state and transient rating studies for continuous, cyclic, and emergency overload conditions.
• Modeling of single-core and three-core cables, sheath losses, and bonding configurations (single-point, both-ends, and cross-bonding).
• What-if and optimization tools to compare layouts, spacings, and backfill properties for capacity and temperature margins.
• Comprehensive, editable libraries of cable constructions and materials.
• Clear reporting with calculation summaries, thermal profiles, and charts suitable for documentation and compliance.

CYMCAP Rev streamlines cable rating studies, supports standards-based decisions, and reduces risk when planning new installations or uprating existing circuits.
