Abstract
The invention relates to a multifunctional braided shielded transponder data transmission cable and a manufacturing method thereof. The multifunctional braided shielded transponder data transmission cable comprises a cable core for transmitting a signal, a power line for transmitting electric power and an outer sheath. A cable core cladding layer, a braided shielding layer and a ring lining layerare arranged between the cable core and the power line in turn from inside to outside. An isolation layer and an armored layer are arranged between the outer sheath and the power line in turn from inside to outside. The multifunctional braided shielded transponder data transmission cable has the beneficial effects that the conventional manufacturing process is eliminated, the signal line and the power line are layered and separated, the signal line and the power line core line do not interfere with each other and the signal transmission is stable; and the reasonably designed signal line and power line combination realizes data information, audio information and power transmission through one cable, cable construction and maintenance are convenient, safety and reliability and space utilization rate are high and the railway construction cost is effectively reduced.
Description
technical field [0001] The application belongs to the field of cable technology, and in particular relates to a multifunctional braided shielding transponder data transmission cable and a manufacturing method thereof. Background technique [0002] Due to the insufficiency of the existing technology, it is necessary to install several power lines in the railway machine room to maintain the daily necessary power supply system, and the connection between the indoor distribution cabinet and the LEU (ground electronic unit) equipment or the connection between the outdoor cable terminal box and the transponder equipment The connection is made with braided shielded transponder data transmission cables. The more power lines and transponder cables are installed, the greater the engineering volume, which not only increases the cost, but also easily leads to confusion in the laying environment and difficulties in maintenance. [0003] At present, some cable manufacturers are also vigo...
