In outdoor underground cable laying projects, fiberglass threading rods are indispensable. They can be used to pull cables through underground conduits, which may be buried at various depths and may contain bends and obstacles. For instance, in a large-scale urban cable upgrade project, fiberglass threading rods were used to thread new fiber-optic cables through existing underground conduits. Despite the presence of numerous bends and the need to navigate around existing utilities, the fiberglass rods successfully completed the task, demonstrating their effectiveness in complex outdoor environments.

IV. Other Important Cable Installation Tools

1. Conduit Threading Equipment

Conduit threading equipment is designed to work in conjunction with threading rods to facilitate the insertion of cables into conduits. It typically consists of a drive unit, a threading head, and a coupling mechanism. The drive unit provides the power to rotate the threading head, which in turn grips the threading rod and pulls it through the conduit. The coupling mechanism allows for the easy connection and disconnection of the threading head to the threading rod.

When using conduit threading equipment with fiberglass threading rods, it is important to ensure a proper fit between the threading head and the rod. This helps to prevent slippage and damage to the rod during the threading process. Additionally, the installer should follow the manufacturer's instructions carefully to ensure safe and efficient operation of the equipment.

2. Cable Pulling Tools

Cable pulling tools are available in a variety of types, including electric pulling machines and manual pullers.
