Shield Tunneling Machine Cable with Enhanced Durability

Shield tunneling machine (TBM) dedicated cables are special cables designed to withstand the complex working conditions of TBMs, requiring high abrasion resistance, high temperature resistance, tensile strength, and waterproof and explosion-proof properties. Specifically designed for TBMs, these cables primarily provide power transmission and signal control for the TBM and its auxiliary equipment (such as the cutterhead, screw conveyor, hydraulic system, and electrical control system). The cables must meet the requirements for use in complex and harsh tunnel construction environments. They typically contain multiple power and signal cores. The power cores transmit high current, while the signal cores are used for control, monitoring, and communication. Galvanized steel wire or steel tape armor enhances the cable's tensile strength and abrasion resistance, adapting to the frequent movement and bending of the TBM. The conductors are made of multi-strand fine copper wire, improving cable…
