Answer: An overhead electricity transmission line consists of several essential components that work together to ensure reliable power delivery. The primary components are:

• Conductors: The actual wires that carry the electrical current. They are typically made from aluminum with a steel core for strength, known as ACSR (Aluminum Conductor Steel Reinforced).

• Insulators: These are crucial for preventing the electrical current from leaking to the supporting structure and the ground. They are made from materials like porcelain, glass, or polymers and are attached to the towers or poles.

• Support Structures: These are the towers or poles that keep the conductors suspended at a safe height. They can be lattice-steel towers, tubular steel poles, or wooden poles, depending on the voltage and terrain.

• Hardware and Fittings: A variety of clamps, connectors, and other accessories are used to secure the conductors to the insulators and the structures.

Ningbo Changshi manufactures and exports a comprehensive range of these tools and accessories, including hydraulic wire cutters, come-along clamps, and conductor drum lifting jacks, to support every stage of an overhead line project.
