Which conductor type is considered a self-damping conductor?

• A. AAAC
• B. AAC
• C. ACSR
• D. VR

Answer: (D)

Self-damping conductors are built to dissipate wind-induced vibrational energy within the conductor itself, using specialized material and strand construction that adds internal damping. This means they reduce vibration amplitudes without needing external dampers. The VR conductor is designed to be vibration-resistant, providing that inherent damping property. In contrast, AAC and AAAC are standard aluminum conductors without extra damping features, and ACSR relies on a steel core for strength but does not inherently provide self-damping to the same extent. So, the VR type best fits the idea of a self-damping conductor.
