Answer from Ningbo Changshi: Protecting delicate signaling cables is a top priority as their integrity is vital for railway safety. The key is to control every aspect of the pulling operation to minimize stress and friction.

Here are the professional methods we recommend:

1. Use of Constant Tension Winches: Our winches are equipped with precise tension control systems and integrated digital tension meters . These features allow the operator to set and maintain a specific pulling force, preventing over-tensioning that could stretch or damage the cable's conductors or insulation.

2. Employing High-Quality Rollers: Using the correct type and number of underground-Cable-Laying-Equipment-and-Tools.html target='_blank'>cable rollers ensures the cable is supported and guided smoothly at every point along the route, eliminating points of high friction and abrasion.

3. Application of Cable Lubricant: A professional, non-staining cable lubricant reduces the pulling force required, especially when cables are pulled through conduits with multiple bends. This simple step can significantly lower the risk of damage.

4. Using Proper Grips and Swivels: Specialized cable grips (socks) and Swivel connectors are used to attach the pulling rope to the cable. The swivel prevents the cable from twisting under tension, while the grip distributes the pulling force evenly across the cable's surface.

By implementing these best practices with our professional equipment, you can ensure a safe and successful installation, preserving the longevity and reliability of the railway's critical signaling infrastructure.
