CYMCAP 9.0 is a specialized power cable ampacity software developed by CYME International, now part of Eaton’s Brightlayer Utilities suite, designed for precise calculation of ampacity and temperature rise in power cable installations. Below is a detailed overview based on available information:
Key Features of CYMCAP 9.0
Core Functionality:
Performs steady-state and transient thermal cable rating calculations using analytical techniques from Neher-McGrath and IEC standards (IEC 60287, IEC 60228, IEC 60853).
Determines the maximum current power cables can sustain without deteriorating electrical properties, critical for designing and upgrading electrical installations.
Enhances system reliability and optimizes equipment utilization by providing accurate cable modeling.
New Features in Version 9.0:
3D Modeling Add-On Module: Enables three-dimensional thermal analysis for non-standard cable geometries and complex crossings, particularly in congested areas.
Advanced Tunnel Modeling Module: Supports steady-state ampacity calculations for ventilated tunnels with multiple dissimilar cables in random geometric arrangements.
These modules expand modeling capabilities for complex installations, improving accuracy in challenging environments.
Cable Modeling Capabilities:
Supports a wide range of cable types, including single-core, three-core, belted, pipe-type, submarine, sheathed, retrofitted, and armored cables.
Includes detailed modeling of special cable construction layers (e.g., jackets around each core, double armor, corrugated sheaths, metallic tapes, flat armor wires).
Features a dedicated cable library with real-world examples from manufacturers and calculates electric field strength for HVDC cables, a key factor in ampacity.
