CYMCAP Rev 3

CYMCAP Rev 3 by CYME is specialized engineering software for calculating the current-carrying capacity (ampacity) and temperature performance of power cables under a wide range of installation and loading conditions. Used by utilities, consultants, EPCs, and cable manufacturers, it helps design, rate, and verify underground and submarine cable systems with confidence and compliance.

Key capabilities:

• Steady-state, cyclic, and emergency (short-term) ampacity calculations with temperature limits
• Thermal modeling for direct-buried cables, duct banks, conduits, tunnels, and submarine installations
• Support for single-core and three-core cables in flat or trefoil formations, with multiple circuits and spacing options
• Consideration of mutual heating, adjacent heat sources, soil thermal resistivity, thermal backfills, and drying-out effects
• Sheath bonding and loss evaluations (single-point, cross-bonded, and solid bonding), including shield, armor, and jacket losses
• Transient thermal analysis for load variations and contingency scenarios
• Cable crossings, joints, and terminations modeled for localized thermal effects
• Standards-based methods, including industry practices derived from IEC and IEEE methodologies
• Intuitive trench and duct bank builders with graphical layouts, plus comprehensive tabular and graphical reports for documentation and comparison

Benefits:

• Optimizes cable sizing, installation layouts, and thermal backfill specifications
• Increases system reliability by validating ratings for normal, cyclic, and emergency conditions
• Reduces project risk through accurate modeling of real-world configurations and thermal interactions
• Streamlines studies and reporting for planning, design, and regulatory compliance

CYMCAP Rev 3 delivers a rigorous, standards-aligned approach to cable rating and thermal design, enabling efficient, defensible decisions across the cable system lifecycle.
