CYMCAP allows engineers to map out exactly how much current (ampacity) a cable can handle under specific conditions without triggering a thermal runaway event. Key Structural Parameters Modeled in CYMCAP:
Engineers use CYMCAP's complex thermal modeling parameters to avoid the conditions that lead to hot cracking: 1. Soil Thermal Resistivity (
Soil behavior dictates how fast heat can move away from a buried cable line. CYMCAP lets users build multi-layered soil profiles. If the software calculates that the soil temperature will cross a specific threshold, it flags the threat of moisture migration—the root cause of soil-induced hot cracking. 2. Cyclic and Transient Loading cymcap hot crack
While often confused with the power cable ampacity software, the "Hot Crack" is a physical tool for musicians, whereas CYMCAP is a thermal analysis software used by engineers to calculate the temperature rise and current-carrying capacity of high-voltage cables. Key Features of the Cymcap Hot Crack
Most modern medium and high-voltage cables rely on insulation. While XLPE features a standard continuous operating limit of 90°C, operating above this threshold accelerates thermo-oxidative degradation. The cross-linked polymer chains begin to sever, causing the material to lose its native flexibility and mechanical tensile strength. 3. Thermomechanical Stress CYMCAP allows engineers to map out exactly how
A "hot crack" is the ultimate consequence of thermal mismanagement. It can lead to , electrical faults , and even catastrophic cable failure, resulting in costly unplanned outages and safety hazards.
: Move beyond steady-state. Model how cables react to peak loads over time to ensure they don't hit "hot" thresholds during emergency cycles. Duct Bank Optimization CYMCAP lets users build multi-layered soil profiles
In 2019, a welding contractor in the North Sea reported a 12% rejection rate on final capping passes due to Cymcap hot cracks. The welds were made on 2-inch thick DH36 steel using FCAW (Flux-Cored Arc Welding).
