Cable Duct Proving Mandrel

Cable Duct Proving Mandrel: The Essential Pre-Installation Tool for Protecting Your Cables

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that the integrity of your cable installation begins with a clear and unobstructed path. Pulling an expensive cable through a compromised or fouled duct can lead to costly damage, project delays, and a significant risk of failure. Our Cable Duct Proving Mandrel is a professional-grade solution meticulously engineered to eliminate this risk. This simple yet critical tool is designed to be pulled through a conduit or duct prior to cable installation. Its robust construction and precise design effectively remove debris, mud, and other obstructions (or "fouls") while simultaneously proving that the duct is clear and properly sized. It is an indispensable step for any professional committed to a flawless, damage-free cable pull. 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 duct mandrel exemplifies our unwavering commitment to providing innovative, durable, and highly efficient solutions that are critical for modern construction and maintenance.
