What are the main components of an overhead distribution line?
2025-08-13An overhead distribution line is a carefully engineered system of interconnected parts. The main components can be broken down into three categories:
-
Supports and Structures: The most visible component is the utility pole, which can be made of wood, concrete, or steel. These structures support all the other components and must be strong enough to withstand the mechanical stress of wind, ice, and conductor tension.
-
Conductors and Insulators: Conductors are the wires (usually bare aluminum or ACSR) that carry the electrical current. Insulators, made of materials like porcelain or polymer, are attached to the poles and separate the live conductors from the pole to prevent electrical leakage.
-
Hardware and Protection: These include a wide range of smaller but equally critical parts, such as crossarms (which hold the conductors and insulators), lightning arresters (to protect against surges), and grounding wires (to provide a path to the earth for excess electricity).
Our company manufactures the equipment and tools to handle the installation and maintenance of every one of these components, from the heaviest structures to the smallest fittings.
