Heavy-Duty Anti-Twist Running Board for OPGW Installation | Guide Tool for 11–16mm Fiber Cable
The Heavy-Duty Anti-Twist Running Board is a specialized guiding tool designed for safe and efficient OPGW (Optical Ground Wire) installation on transmission lines. Engineered for cables with 11-16 mm diameter, this running board keeps the cable stable and prevents rotational stress, ensuring smooth stringing in both overhead and long-span projects. Built from high-strength alloy steel and precision-machined rollers, it provides exceptional durability and reliability in demanding field environments.
What Is an Anti-Twist Running Board?
An anti-twist running board is a mechanical guide device used during conductor or OPGW stringing to maintain cable orientation and eliminate twisting as it travels through pulleys and blocks. It ensures uniform tension distribution, prevents fiber damage inside OPGW, and supports accurate positioning during power line construction.

Frequently Asked Questions
What cable sizes can this running board support?
It is designed for 11-16 mm OPGW, ADSS, and similar conductors.
Why is anti-twist protection important for OPGW?
OPGW contains optical fibers. Twisting can cause severe fiber deformation, signal loss, or long-term damage. The running board ensures stable, twist-free pulling.
Is it compatible with standard transmission line pulleys?
Yes, the running board fits most U-shaped, single-sheave, and large-diameter stringing blocks.
Can it be used in harsh environments?
Absolutely. Its high-strength steel frame and anti-corrosion finish are designed for outdoor, high-humidity, and high-altitude conditions.
Does it require maintenance?
Only basic cleaning and lubrication of rollers after extended use.
