Bundled Circuit Design for 115-138 kV Compact Transmission Lines Volume 1

摘要

Bundled circuit lines combine compact line principles with the bundled conductor technology commonly used or transmission lines. By supporting the three phase conductors with a complete insulator system rather than individual phase insulators, and by adding insulating misspend spacers where necessary to maintain clearances between conductors, a circuit can be designed requiring little more space than a conventional 3-conductor bundle. Such designs offer advantages for compact application, particularly for appearance and ease in uprating existing lines. Non-ceramic fiberglass-cored insulators which are strong, resilient, lightweight, and visually unobtrusive, are an important complement to this construction.
