Common usage issues of fiberglass threading device

Although fiberglass cable connectors have advantages such as insulation, corrosion resistance (based on actual reports), and lightweight in practical engineering applications, they may still encounter some common problems during use, affecting construction efficiency and even causing equipment damage. The following are typical problems, their causes, and coping strategies:

1. The threading device is stuck or unable to pass through the pipeline

This is one of the common problems, usually caused by foreign objects inside the pipeline, small bend angles, sudden changes in pipe diameter, or multiple sharp bends. In addition, if the diameter of the threading device is too large or the surface is not lubricated, it will significantly increase the frictional resistance. The solution includes thoroughly cleaning the pipeline before construction; Choose a threading device with appropriate diameter and flexibility; Alternate pushing from both ends when needed; Use a one-to-one threading lubricant to reduce friction.

2. Breakage or delamination of the threading device

It often occurs when forcibly crossing obstacles, overloading traction, or when the threading device has aged. Although fiberglass material has good strength, its impact resistance and repeated bending ability are limited, especially in low-temperature environments where it is prone to brittleness. If the threading device has been exposed to prolonged sunlight, moisture, or has not been inspected after multiple uses, the internal resin may degrade, leading to structural failure. Violent operation should be avoided, and the rod body should be regularly inspected for whitening, cracks, or exposed fibers. If any abnormalities are found, they should be stopped immediately.

3. Front end guide head falls off or is not firmly connected

Some threading devices are equipped with metal or plastic guide heads at the front end for easy threading of pipes. If not installed tightly or tied securely, they are prone to falling off during the pulling process, causing threading failure or even requiring re threading of pipes. It is recommended to use guide heads with threaded locking or hot melt fixation, and to use double binding or one-to-one connection kits when connecting cables to confirm excellent traction process.

4. Surface fuzzing and scratching of cables

After long-term use or repeated friction in rough pipelines, fiber warping or resin peeling may occur on the surface of the threading device, forming burrs. These burrs may scratch the cable sheath during the traction process, especially posing a significant threat to optical cables or thin-walled communication cables. Before use, it should be carefully inspected and polished with fine sandpaper. In severe cases, it should be scrapped and replaced.

5. Risk of rebound injury

The fiberglass threading device has a definite elastic energy storage characteristic. When suddenly released or broken in a curved pipeline, it may cause severe rebound, which can harm the operator. Therefore, it is strictly prohibited to stand in front of the threading device axis during operation. It is recommended to wear protective goggles and gloves, and use a slow and uniform pushing and pulling method.

6. Decreased insulation performance

Although fiberglass itself is an excellent insulator, if the surface is contaminated with conductive dust, oil, or exposed to high humidity for a long time, it may form surface leakage channels during high-voltage operations. When used for threading in power systems, the threading device should be kept clean and dry, and insulation resistance testing should be conducted if necessary to confirm its safety.

7. Roll deformation or memory effect

Long term coiled storage of the threading device may result in "memory bending", which means it is difficult to fully straighten after unfolding, affecting the smoothness of threading. It should be wound according to the specifications (the roll diameter should not be too small), stored in a flat and dry place, and can be pre stretched or naturally stretched at room temperature for a period of time before use.

Most of the above problems can be effectively avoided through standardized operation, regular maintenance, and reasonable selection. The key is to treat fiberglass cable connectors as engineering tools that need to be managed, rather than disposable consumables, in order to protect construction safety and efficiency.
