This is one of the most common and critical questions in the industry. The best method depends on the project's specific requirements.

• Cable Pulling: This traditional method involves using a winch and pulling rope to draw the cable through a conduit. It is generally better for shorter distances and projects with limited space. However, it can cause more friction and stress on the cable, potentially leading to damage.

• Cable Blowing (Jetting): This modern method uses high-pressure air to float or push the cable through the conduit, often with a motorized pushing mechanism. It is ideal for long distances, and routes with multiple bends or elevation changes. The use of compressed air significantly reduces friction, minimizing the risk of cable damage and allowing for faster installation over thousands of meters. It is also more labor-efficient.

Professional Answer: At Ningbo Changshi, we understand that selecting the right installation method is crucial for project success. While cable pulling is effective for shorter, more direct runs, we often recommend our fiber optic cable blowing machines for underground projects that involve long distances or complex routes with bends. Our blowing equipment uses a combination of mechanical force and high-pressure air to gently and efficiently propel the cable, drastically reducing friction and the risk of damage. This method not only extends the potential installation distance but also saves significant time and labor costs.
