What are the essential components that make up an Overhead Power Transmission Line system?
2025-07-18An OHTL system comprises several critical components working in synergy:
-
Conductors: These are the wires that carry the electrical current. Most commonly, they are made of aluminum conductor steel reinforced (ACSR) for a balance of conductivity, strength, and weight. We offer a range of specialized conductor tools.
-
Insulators: Typically made of porcelain, glass, or polymer composites, insulators provide electrical isolation between the live conductors and the grounded support structures, preventing current leakage.
-
Support Structures: These are the towers (lattice, tubular, or monopole) or poles that physically hold the conductors and insulators at a safe height above ground.
-
Crossarms: Mounted on the support structures, crossarms provide the necessary spacing and support for the insulators and conductors.
-
Ground Wires (Shield Wires): Positioned at the top of the structures, these wires primarily protect the phase conductors from direct lightning strikes.
-
Hardware & Fittings: A wide array of clamps, connectors, vibration dampers, and other accessories that secure conductors, connect insulators, and ensure the mechanical integrity of the line. Our product range includes high-quality hardware and fittings for all OHTL applications.
