Balance Type 130 KN Four Bundle Conductors Running Boards for Overhead stringing line
Designed for efficient overhead transmission line stringing, this four-bundle conductor running board ensures smooth and balanced tension distribution during installation. Its balanced-type structure prevents twisting and uneven load, while the 130kN (13-ton) working load limit makes it ideal for high-voltage and extra-high-voltage power line projects. Built for durability and safety, it is a critical tool for reliable conductor stringing operations.
Engineered for high-capacity overhead transmission lines, this four-bundle running board features an optimized balanced-load mechanism to minimize conductor wear during stringing. With a 130kN (13-metric ton) load rating, it accommodates the rigors of large-diameter or high-tension conductor installations. The robust construction ensures stability across uneven terrain, while its smooth-rolling design enhances operational efficiency in grid construction and maintenance projects.
