Abstract

The invention discloses a DC cable with high performance for subway, including a cable, and a socket and a plug fixedly connected to both ends of the cable, the plug is provided with a cavity inside,the left side wall of the cavity is fixedly connected with a mounting plate, the right end of the upper surface of the mounting plate is movably sleeved with a T-shaped rod through a first through hole, the upper end of the vertical part of the T-shaped rod is fixedly connected with an indicator plate, the upper end side wall of the cavity is provided with a rectangular hole, the rectangular holeis matched with the indicator plate, a first spring sleeves the rod wall of the T-shaped rod, one end of the first spring is fixedly connected with the indicator plate, and the other end of the firstspring is fixedly connected with the mounting plate. The cable is convenient to operate; the cable can be laid in sections according to a certain length, the damaged cable can be indicated, the time for maintenance personnel to detect the cable is reduced, it is convenient to replace the damaged cable quickly, and the waste of the cable is reduced.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-performance DC cable for subways. Background technique [0002] The cable is usually a rope-like cable twisted by several or groups of wires [at least two in each group]. Each group of wires is insulated from each other and is often twisted around a center. The insulating covering layer is mostly erected in the air or installed underground or underwater for telecommunications or power transmission, especially in the construction and transportation of urban rail transit. The cables are installed underground, which not only requires the cables to have a higher Compressive performance, but also to facilitate installation and laying and inspection and maintenance. [0003] After retrieval, the Chinese patent authorization number is CN101714417B, which discloses a DC cable for subways, which includes a conductor, the conductor is made of tinned copper wire, and the strand is ma...
