On behalf of Ningbo Changshi, an 11kv overhead line is a complete system requiring various components to function safely and reliably. Key components include:

• Poles/Towers: These structures, often made of wood, concrete, or steel, provide the physical support for the conductors.

• Conductors: The bare or insulated wires that carry the electrical current. Common types for 11kv lines include AAC (All Aluminium Conductor), AAAC (All Aluminium Alloy Conductor), and ACSR (Aluminium Conductor Steel Reinforced).

• Insulators: These devices, typically made of porcelain or composite materials, separate the live conductors from the supporting structures, preventing electrical current from flowing to the ground.

• Crossarms and Braces: These provide the necessary spacing between conductors and support the insulators. They are available in various materials and designs to suit different line configurations.

• Line Hardware and Fittings: This includes a wide range of accessories such as clamps, connectors, OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, and vibration dampers, which are essential for securing, joining, and maintaining the conductors and other equipment.

• Earth Wires and Guy Wires: Earth wires provide a path for fault currents, while guy wires and stays are used to provide mechanical stability, especially at angles or dead-end poles.
