preventing freeze cracking lies in\u00a0material low-temperature toughness,\u00a0structural design to avoid stress concentration,\u00a0process control to ensure quality, and\u00a0environmental adaptability design. Material Selection and Optimization (Foundation of Low-Temperature Toughness) Cable Insulation and Sheath Materials: Case:\u00a0A pure electric bus operating in Northeast China frequently experienced brittle cracking of the insulation layer on low-voltage signal wires inside the battery pack during winter, leading to signal loss. Solutions: Select Specialized Cold-Resistant Materials:\u00a0Switch from ordinary PVC materials to\u00a0specialized cold-resistant TPE, TPU, silicone rubber, or modified XLPO. For example, use silicone rubber insulated cables rated for -55\u00b0C or even -70\u00b0C.
