: Polymer insulation can become brittle or "crack" over time due to accelerated thermal aging. Soil Dry-Out
In CyMCAP, refers to the methodology of selecting cable sizes based on their expanded diameter at maximum operating temperature. When a cable carries current, it generates heat (Joule effect), causing the materials (insulation, sheath, and jacket) to expand thermally. cymcap hot crack
is a form of material failure that occurs at high temperatures, often associated with welding or casting, but relevant to conductors under extreme thermal load. In the context of a grounding grid, this phenomenon manifests in two primary ways: : Polymer insulation can become brittle or "crack"
