What is an electrical overhead line and what are its main components?
2025-08-13An electrical overhead line is a structure used to transmit and distribute electrical energy over long distances. It consists of multiple components that work together to ensure the safe and efficient transfer of electricity. The main components are:
-
Conductors: The wires that carry the electrical current. They are typically made of materials like ACSR (Aluminum Conductor Steel Reinforced), which combines the low resistance of aluminum with the mechanical strength of a steel core.
-
Insulators: Devices made from ceramic, glass, or polymer that prevent the conductors from making electrical contact with the supporting structures.
-
Supporting Structures: These are the towers or poles that hold the conductors at a safe height above the ground.
-
Hardware and Fittings: A wide array of clamps, tension fittings, vibration dampers, and other accessories that connect the conductors and insulators to the support structures.
Our comprehensive product range, from OHTL wire cable conductor tension stringing equipment to Overhead Tools and Accessories, is designed to handle and install every one of these components precisely and safely.
