The cable traction swivel is a key equipment for cable laying in power construction. It allows the cable to rotate freely during the traction process, reducing cable kinks and wear, thereby improving construction efficiency and the service life of the cable.

Structure and working principle of cable pulling swivel

The cable traction swivel is mainly composed of a swivel head, bearings, sealing rings, connectors and other parts. The swivel head is usually made of high-strength metal materials and can withstand the tension and torque generated during cable traction. The bearing is located inside the swivel head to ensure that the swivel head can rotate flexibly and reduce friction. The sealing ring is used to prevent dust and moisture from entering and protect the internal bearing from damage.

When working, the pulling swivel is installed between the cable traction machine and the cable. When the traction machine pulls the cable, the swivel head of the swivel will rotate with the movement of the cable, allowing the cable to rotate freely during the traction process. This design effectively avoids the kinks and wear of the cable caused by being fixed during the traction process.

How to use the cable pulling swivel

When using the wire pulling swivel for cable laying, you need to follow the following steps:

1. Preparation: Before starting to lay, you need to check the cable pulling swivelto ensure that its components are intact and functioning properly.
2. Install the rotary joint: Install the rotary joint between the cable traction machine and the cable to ensure a firm connection to avoid falling off during traction.
3. Pull the cable: Start the traction machine, slowly pull the cable, and observe the rotation of the rotary joint to ensure that it works properly.
4. Inspection and adjustment: During the traction process, regularly check the status of the cable and the rotary joint. If there is any abnormality, stop traction and make adjustments in time.

Application of cable pulling swivel in cable laying

The cable pulling swivel is widely used in cable laying. It can not only be used for cable laying in power systems, but also for cable laying in communications, networks and other fields. In practical applications, the rotary joint can effectively improve the laying efficiency, reduce the difficulty of construction, and reduce the construction cost. The following are the applications of cable pulling swivels in cable laying:

1. Improve laying efficiency
2.  

The cable pulling swivel allows the cable to rotate freely during the traction process, reducing the kinking and wear of the cable during the traction process. This design makes cable laying smoother and significantly improves the laying efficiency, especially in long-distance or complex terrain laying projects.

2. Protect the cable
3.  

During the cable laying process, the cable may encounter various obstacles or curved paths, which may cause damage to the cable. The cable pulling swivel effectively disperses the stress of the cable during the traction process by allowing the cable to rotate freely, thereby protecting the cable from damage and extending the service life of the cable.

3. Reduce construction difficulty
4.  

When urban power grid transformation or new communication network construction, cable laying often needs to pass through complex underground pipelines or narrow spaces. The use of cable pulling swivels can effectively reduce the construction difficulty, avoid kinking and wear caused by the immobilization of the cable, and make cable laying more flexible and convenient.

4. Adapt to different laying environments
5.  

The design of the cable pulling swivel enables it to adapt to various laying environments, including urban underground pipelines, mountainous areas, tunnels and other complex terrains. Its lightness and durability enable it to maintain good working performance in various environments.

5. Reduce construction costs
6.  

The cable pulling swivel helps reduce construction costs by improving laying efficiency and reducing cable damage. It reduces the additional repair and replacement costs caused by cable damage, and also reduces the manpower and time costs increased by the difficulty of construction.

For example, in the transformation of urban power grids, due to the complexity of urban underground pipelines, traditional cable laying methods often require excavation of a large amount of road surface, which is not only difficult to construct, but also has a great impact on urban traffic and environment. Using a cable pulling swivel, cable laying can be completed without damaging the road surface, greatly reducing the impact of construction on the urban environment and traffic.

As an efficient cable laying tool, the cable pulling swivel plays an important role in modern power construction. It not only improves the efficiency and safety of cable laying, but also reduces the impact of construction on the environment. With the continuous advancement of technology, the performance of the cable pulling swivel will be more perfect, and the scope of application will be wider, providing more powerful technical support for power construction.
