Answer: A bundled conductor is an assembly of two or more individual conductors per phase, spaced a short distance apart. This configuration is used in high-voltage transmission lines to address two major issues: corona effect and inductive reactance. By using a bundle, the effective diameter of the conductor is increased, which reduces the electric field gradient around the wires, thereby minimizing corona loss and radio interference. Additionally, bundling reduces the line's inductance and increases its power transfer capacity. Ningbo Changshi's specialized tension stringing equipment is crucial for accurately and safely installing these complex bundled conductor systems.
