CYME CYMCAP 9.0 Rev 1: Cable Ampacity & Thermal Rating Software

CYMCAP 9.0 Rev 1 is the latest revision of CYME International's industry-standard software for calculating cable ampacity and thermal ratings. It is used by transmission and distribution engineers to accurately model underground cable systems, optimize cable sizing, and prevent premature failure due to overheating .

Key Features in Version 9.0 Rev 1

Standards Compliance & Calculations

• IEC Compliance: Follows international methods such as IEC-60287 (steady-state) and IEC-60853 (cyclic/emergency)

• Neher-McGrath Method: Uses the industry-accepted North American standard for underground cable thermal analysis

• North American Standards: Adherence to NEC and IEEE application guidelines

Cable & Installation Modeling

• Extensive Cable Library: Predefined libraries for single-core, three-core, tape, pipe, submarine, sheathed, and armored cables

• Flexible Installation Options: Model direct burial, thermal backfill, underground ducts, pipe-type, and conduit banks

• Mixed Installation Support: Place various cable types in a single thermal environment

Advanced Thermal Analysis

• Heat Source Modeling: Model external sources such as heat sinks and adjacent utilities

• Cyclic Loading: Simulate daily or emergency load cycles alongside base loads

• Non-Isothermal Surfaces: Accounts for uneven ground surface temperatures

• Soil Thermal Dynamics: Handles varying soil thermal resistivity conditions
