Abstract

The invention provides a high-voltage flexible cable for a shield tunneling machine. The high-voltage flexible cable for the shield tunneling machine comprises a main cable core conductor, a main cable core conductor shielding layer, a main cable core insulation layer and a main cable core insulation shielding layer. Reinforcing-type padding is arranged at the centers of cable cores. A squeezed and packaged semiconductive grounding cable core is arranged between cable cores. Inner protecting sleeves are arranged outside the cable cores. Reinforcing layers are woven outside the inner protecting sleeves. Outer protecting sleeves are arranged outside the reinforcing layers. Wear-resistant layers are arranged outside the outer protecting sleeves. The high-voltage flexible cable for the shield tunneling machine has the advantages of being high in flexibility, bending-resistant, torsion-resistant, tensile and wear-resistant, and is a power cable specifically developed and designed aiming at working characteristics of the shield tunneling machine.

Description

technical field [0001] The invention relates to a cable, in particular to a high-voltage flexible cable for a shield machine that can satisfy both twisting and bending movements. technical background [0002] The purpose of the shield machine is not only to excavate subway tunnels, but it can be widely used in road tunnels, diversion tunnels and other projects. It is compared to "underground aircraft carrier" by the industry. It is not only bulky, but also complex in technology. , electronic components and hydraulic pipelines and other industrial fields. The emerging application direction of the shield machine also includes the construction of urban underground pipe corridors. Drainage pipelines to solve urban waterlogging, uniformly designed and compatible power, heat, and communication pipelines can all be laid with small shield machines to dig out common trenches. Beijing Capital Airport once used a small shield machine to excavate the common trench under the airport ru...
