China overhead line fittings, crafted from iron or aluminum, secure and support conductors in power lines. Various hardware types include clamps for wire installation, hanging rings for insulator strings, crimping and repair tubes for wire connections, and spacer bars for split wires. In addition, cable fittings for pole towers are utilized.
These components not only fix and support wires but also assemble suspension insulators into strings, connecting and hanging them on tower cross arms. Design and manufacturing considerations prioritize strength, stiffness, and wear resistance for long-term use. Selection and configuration of hardware must align with specific line conditions to ensure the safe and stable operation of overhead lines.
Installation Guide for Overhead Power Line Accessories
There are 5 steps for the installation of electrical overhead line fittings:
Preparation and Planning: Conduct a comprehensive site assessment considering terrain, weather, and load requirements.
Assembly and Inspection: Assemble fittings according to manufacturer guidelines, ensuring all bolts and connections are securely tightened.
Lifting and Attachment: Lift and position assembled fittings onto poles or towers, using appropriate lifting equipment.
Alignment and Tensioning: Verify alignment and adjust if necessary.
Final Checks and Documentation: Conduct thorough quality checks, addressing any issues identified during the inspection.
The components of an overhead line, a crucial element in power transmission and distribution, consist of a well-coordinated system of essential elements designed to efficiently transport electrical energy from generation sources to end-users. At its core, an overhead line typically comprises conductors, supporting structures, insulators, and associated hardware.
Conductors form the backbone of the overhead line, serving as the pathway for electricity to flow. These conductors are often made of aluminum or copper, chosen for their excellent conductivity and durability.
Supporting structures, such as poles or towers, play a critical role in elevating the conductors above the ground and maintaining the required clearance. The design and placement of these structures are essential to ensure the stability and reliability of the overhead line.
Insulators, often made of ceramic or composite materials, are strategically placed to electrically isolate the conductors from the supporting structures, preventing unintended paths for current flow. This is crucial for maintaining the integrity and safety of the system.
Additionally, associated hardware such as clamps, connectors, and fittings are employed to secure and connect various components of the overhead line, ensuring a robust and reliable transmission network.
Overhead Line Fittings Overhead line fitting is also called overhead line hardware or overhead line accessories. The overhead line fittings include a wide range of steel fittings that are used to construct the overhead line. Overhead Line Fittings for power utilities and communications other than plant grid construction.

The function of overhead line fittings is to provide a mechanical interface for electrical connections and to hold insulators and conductors in place. In the relevant standards, fittings are harmonized and periodically updated as accessories that may consist of elements or attachments. Accessories for different conductors are designed for the termination, suspension or connection of conductors and are attached directly to the conductor. Dead-end clamps, suspensions, branch clamps, connectors, bundle spacers and anti-vibration accessories are included in this category. Depending on the function, they may form an assembly containing more than one element, including, for example, clamps for connecting couplings. Fittings for insulating sleeves and other accessories are designed to connect tension elements and attachment points at supports.
