Compare aeolian vibration and galloping in overhead conductors: motion, fatigue, clearance risks and why damping devices need mechanism-specific verification.
Calculate overhead conductor sag with a worked SI example. Understand horizontal tension, mass conversion, catenary checks and the limits of a simple formula.
Compare trefoil and flat formation for single-core HV cables across ampacity, sheath losses, bonding, magnetic field, route width, and fault restraint.
Learn which cable dimensions, materials, sheath details, equipment interfaces, qualification evidence, and site controls must match HV joints and terminations.
