Pithead Roller for Wellhead Bus-Bar Cable Protection

Pithead Roller: The Essential Guide for Wellhead Bus-Bar Cable & Rope Protection

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that a successful underground cable installation depends on managing every critical transition with precision and care. One of the most challenging points is the change of direction at the top of a vertical shaft, often referred to as a "wellhead" or "pithead." This is where the cable is pulled from a vertical position into a horizontal one, creating immense stress and a high risk of damage from sharp edges. Our Pithead Roller for Wellhead Bus-Bar Cable Protection is a specialized and indispensable tool meticulously engineered to solve this problem. It is designed to protect both the "Cable (maximum Φ80)" and the "pulling rope" as they navigate this critical transition. As a prominent China manufacturer and exporter specializing in comprehensive one-stop supply and services for both overhead transmission line (OHTL) wire cable conductor tension stringing equipment and underground cable laying equipment, this pithead roller exemplifies our unwavering commitment to providing innovative, durable, and highly efficient solutions that are critical for modern construction and maintenance.

The Pithead Roller is designed for secure placement at the top of a manhole or wellhead. It provides a large-radius, low-friction surface that guides the cable smoothly from the vertical pull to the horizontal bus-bar. This design offers several key advantages:

• Dedicated Wellhead Protection: Specifically engineered to provide a smooth, protected path for cables and pulling ropes at the crucial transition point of a wellhead, preventing contact with sharp, abrasive edges.

• Dual Protection for Cable & Rope: The robust roller is designed to handle both the cable and the pulling rope simultaneously, protecting both valuable assets from wear and tear.

• Low-Friction, High-Efficiency Pulls: The smooth-rolling action of the roller significantly reduces the friction exerted on the cable, which in turn lowers the pulling force required, making the installation faster, safer, and less strenuous on equipment.

• Designed for Specific Cable Sizes: The guide is optimized to handle cables up to a "maximum Φ80mm," providing a perfect fit and ideal protection for a common range of conductors.

• Enhanced Stability: The robust frame is designed for secure placement at the pithead, ensuring the roller remains stable and reliable throughout the entire pull.

By deploying Ningbo Changshi's Pithead Roller, you invest in a practical, durable, and essential tool that provides an elevated level of control and protection at the most critical point of your cable installation, saving time, reducing costly cable damage, and ensuring the safety and integrity of your projects.

Product Features & Benefits:

• Specialized Pithead Design: Meticulously engineered for the specific application of guiding cables and ropes at the vertical-to-horizontal transition of a wellhead or manhole.

• Cable & Rope Protection: The robust roller provides a smooth surface, preventing damage to both the cable jacket and the pulling rope from the sharp edges of the wellhead.

• Accommodates up to Φ80mm: Optimized to provide a perfect fit and ideal protection for cables with a maximum diameter of 80mm.

• Reduces Friction & Pulling Force: The smooth-rolling action of the roller significantly decreases the effort required, making installation easier and more efficient.

• Heavy-Duty Construction: Built with a strong frame and a durable roller to withstand the forces of a high-tension pull and provide a long service life.

• Enhanced Safety: By providing a stable and secure guide, the roller reduces the risk of accidents and equipment strain at a high-stress point of the installation.

Product Applications:

Our Pithead Roller is an indispensable tool for a wide range of specialized cable handling and deployment projects:

• Underground Electrical Network Construction: Essential for pulling cables into and out of manholes and other vertical access points.

• Substation & Industrial Installations: Ideal for deploying cables into vertical utility shafts within complex industrial facilities.

• Telecommunications Network Installation: Facilitates the installation of large-diameter telecommunications cables into underground vaults.

• Any Project with Vertical Cable Transitions: Applicable wherever a smooth, low-friction, and damage-free path is needed for a cable moving from a vertical to a horizontal direction.
