What performance characteristics and environmental adaptations define cables suitable for transformer interconnections in power transmission grids?

Transformer connection cables require specialized engineering to address dual operational challenges: maintaining electrical integrity under high-voltage stress and enduring harsh environmental exposure. These components must exhibit robust dielectric strength to handle transient voltage fluctuations common in transformer operations, while their outer sheathing incorporates weather-resistant compounds to withstand UV radiation, temperature extremes, and moisture ingress—critical features for outdoor installations where arcing mitigation necessitates open-air placement. Mechanical durability is equally essential, with reinforced construction to resist vibration-induced fatigue and physical abrasion during long-term service.
