Overhead line fittings are essential accessories used in power systems to connect and support various components, ensuring the eficient transfer of mechanical and electrical loads while providing protection.
These fittings play a crucial role in the power grid, where numerous cross nodes exist within the transmission and distribution network. At each intersection point, proper fixation is required to maintain structural integrity and electrical continuity.
The power grid consists of substations, which serve as intermediate nodes, and power towers, which suport the main transmission lines.To ensure the seamless transmission of electrical energy, overhead line fitings facilitate secure conductor contact andm aintain a suficient current-carrying capacity, enabling high-power distribution across the network.

The Concept of Overhead Line Fixtures
Overhead line fixturesareessential metal accessories used inpower transmissionsystems,typically made of iron, aluminum, or aluminum alloy.They play acrucial role in supporting and securing various components within the power grid.
These fixtures connect and support boost and buck substations, distribution equipment, and conductors,ensuring theseamless transmission of electrical energy.They also facilitate the connection between transmission line conductors, insulators, and supporting structures, forming a stable and efficient system.
In the context of overhead transmission lines, these metal accessories-often referred to as line fittings-serve several critical functions, including:
– Connecting conductors securely.
-Linking insulators into a string.
– Attaching insulators to transmission towers.
– Providing mechanical support and electrical continuity.
Overhead line fixtures must possess sufficient mechanical strength, durability, and flexibility to withstand high electrical loads and environmental stresses.As integral nodes in the power grid, their design and manufacturing adhere to strict safety standards to ensure reliable operation and structural integrity.
