Question

State any four properties of conductor material used for overhead conductor.

Answer 1

Here are four important properties of conductor materials used for overhead conductors:

1. High Electrical Conductivity: The material should allow electric current to pass through it easily, minimizing energy loss. Copper and aluminum are common materials because they have excellent conductivity.
   

1. Low Temperature Coefficient of Resistance: The material should not have a significant increase in resistance with rising temperature, as this would lead to power losses. This property helps maintain stable performance even under changing environmental conditions.
   

1. Mechanical Strength: The material must be strong enough to withstand tension, wind pressure, and other mechanical stresses. This ensures the conductor doesn't break or sag over long distances.
   

1. Corrosion Resistance: Overhead conductors are exposed to outdoor conditions, so the material should resist corrosion from environmental factors like moisture and air. This increases the longevity and reliability of the conductor.
   

These properties ensure efficient and durable operation of overhead power transmission lines.
