If a CYMCAP simulation indicates a high risk of overheating, several mitigation strategies are typically employed:
CYMCAP is not a "cracking tool"; rather, it is a highly specialized analytical tool developed by Eaton (formerly CYME). Its primary mission is to calculate the of a power cable. cymcap hot crack
Welder technique matters. A cold crater (abrupt stop) creates a solidification void. As the weld cools, the surface tension pulls the crater apart, initiating a crack that runs back into the cap. If a CYMCAP simulation indicates a high risk
The primary function of CYMCAP is to accurately predict where and when a cable's temperature will exceed safe limits. It calculates the steady-state and transient temperature of the conductor, sheath, and armor. A 2017 study comparing CYMCAP predictions with field measurements from an underground 69 kV cable installation concluded that the software is capable of predicting . The study noted that the location of the hotspot in the main power cable was the same as in an adjacent spare duct, proving the model's accuracy in identifying vulnerable areas.

Modify the design to allow the components to shrink freely. Avoid tight fit-ups that restrict movement.
Moisture entering the crack, leading to a short circuit.
