A cross-linked polyolefin insulated low-smoke, halogen-free, flame-retardant rail vehicle cable

Abstract

The invention discloses a cross-linked polyolefin insulated low-smoke halogen-free flame-retardant rail vehicle cable, which includes an outer protective layer, the inner wall of the outer protective layer is fixedly connected with a waterproof layer, and the inner wall of the waterproof layer is slidably connected with an inner protection layer. layer, the outer wall of the inner protective layer is fixedly connected with several uniformly distributed contact copper rings, and the outer walls of several contact copper rings are fixedly connected with the inner wall of the flame-retardant material layer; the inner wall of the waterproof layer is fixedly connected with a plurality of sliding rails distributed at intervals, the inner walls of the plurality of sliding rails are respectively slidably connected to one ends of the plurality of sliders, and the other ends of the plurality of sliders are respectively fixedly connected to the outer walls of the plurality of heat dissipation copper rings, The inner walls of several heat-dissipating copper rings are fixedly connected with several uniformly distributed heat-conducting sheets. The cross-linked polyolefin-insulated low-smoke, halogen-free, flame-retardant rail vehicle cable provided by the present invention has low combustion risk and excellent flame-retardant effect. Good, and the cable has strong pressure and impact resistance, and is easy to disassemble.

Description

technical field [0001] The invention relates to a rail vehicle cable, in particular to a cross-linked polyolefin insulated low-smoke, halogen-free, flame-retardant rail vehicle cable. Background technique [0002] Rail transit refers to a type of vehicle or transportation system in which operating vehicles need to run on specific tracks. The most typical rail transit is a railway system composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit presents more and more types, which are not only used in long-distance land transportation, but also widely used in short- and medium-distance urban public transportation. Rail transit is the current national economy. The foundation and core of development, the expansion and speed-up of rail transit is the background of our commitment to the development of rail transit cables, and high-speed moving rail vehicles also have higher requirements for cables. The imp...

With the diversified development of train and railway technology, rail transit presents more and more types, which are not only used in long-distance land transportation, but also widely used in short- and medium-distance urban public transportation. Rail transit is the current national economy. The foundation and core of development, the expansion and speed-up of rail transit is the background of our commitment to the development of rail transit cables, and high-speed moving rail vehicles also have higher requirements for cables. The impact resistance of existing rail vehicle cables and Insufficient flame retardant performance, poor safety in long-term use and inconvenient disassembly and installation
