CYMCAP (Cym-Capacity) is designed to model the complex thermal environment of underground installations. It uses the and Neher-McGrath methods to ensure that cables operate within safe temperature limits, specifically to avoid the conditions that lead to hot cracking. 1. Identifying Thermal Bottlenecks
Q: What causes Cymcap hot cracks? A: Cymcap hot cracks can be caused by chemical exposure, extreme temperatures, medical conditions, poor skin care, and occupational exposure.
Mitigating Thermal Hot Spots and Soil Cracking in High-Voltage Cable Infrastructure: A CYMCAP Analytical Guide
Maintain a slightly convex cap with a reinforcement of 1/16 to 1/8 inch. A convex bead has compressive residual stresses on the surface, resisting crack propagation.
For specific advice on a Cymcap alloy or process, consult the material supplier’s welding procedure specification (WPS) and perform a cast-sensitive hot cracking test such as the Varestraint or Transvarestraint method.
