2. To organize and support electrical cables in overhead and underground installations

3. To enhance the aesthetics of powerline areas

4. To store excess materials from electrical installations

The correct answer is: To organize and support electrical cables in overhead and underground installations

The primary function of cable trays in powerline work is to organize and support electrical cables in both overhead and underground installations. These trays serve as a structured pathway that holds cables securely, which helps to prevent damage, tangling, and wear over time. By providing a clear layout for the cables, cable trays facilitate maintenance and inspection, ensuring that cables are easily accessible and can be managed efficiently. This systematic organization is crucial in powerline work because it enhances safety by reducing hazards associated with exposed or unorganized cables. Additionally, cable trays can accommodate changes in installation or expansion of electrical systems, making them a versatile solution for managing electrical infrastructure.
