What are the mainly fucntion of the cable ground roller?

cable ground roller, also known as cable roller or corner ground roller, is a device used as underground cable installtion tools  and has the following main functions:

1. Guiding and supporting cables: cable protection roller are usually installed at the bends of cable lines to guide and support cables. In a cable system, cables pass through multiple points, and cable pulleys can ensure that cables move along the designed path, avoiding sagging or twisting caused by the weight of the cables themselves, external environment, and other factors.

2. Reduce cable tension: Cable pulleys can reduce cable tension, especially in areas where there are bends or changes in direction in the cable route. By providing appropriate support, it helps to reduce the stress on cables and prevent them from being damaged due to excessive tension.

3. Preventing cable wear: The surface of cable pulleys is usually smooth and designed to reduce friction between the cable and the pulley. This helps prevent surface wear of the cable and extend its lifespan.

4. Maintaining cable routing: Cable pulleys help keep cables in a specific direction, ensuring the overall structure and layout of the cable system. This is crucial for maintaining the stability and reliability of the cable system.

5. Adapt to various environments: Cable pulleys are usually made of durable materials and can adapt to different environments, including indoor, outdoor, high temperature, low temperature, and other conditions. This enables them to run reliably in various application scenarios.
