Embodiment Construction

[0013] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0014] like figure 1 and figure 2 As shown, a European standard reduced-size rail transit vehicle control jumper flexible cable of the present invention includes a tinned soft-bundled stranded conductor 1, and a thin-walled reduced-sized elastic body insulating layer 2 is arranged on the outside of the tinned soft-bundled stranded conductor 1. Tin-plated soft-bundled conductor 1 and thin-wall reduced-size elastomer insulating layer 2 form a thin-wall type reduced-size insulated wire. The thin-wall type reduced-size insulated wire is separated into cables and the center core of the cable is yellow / green Native wire core 3, thin-wall type reduced-size insulated wires are ...

Abstract

The invention relates to the technical field of wire and cable accessory devices for rail transit vehicles, specifically to an European standard reduced-size rail transit vehicle control bridging flexible cable, which is environment-friendly, flexible, fireproof, smokeless, non-toxic, flame-retardant, aging-resistant, high/low-temperature-resistant, weather-resistant and the like, is excellent inenvironment-friendly effect, simple in structure and mature in preparation process, is beneficial to reducing the manufacturing cost, and comprises a tinned soft bunch-stranded conductor, wherein a thin-wall reduced-size elastomer insulating layer is arranged outside the tinned soft bunch-stranded conductor, the tinned soft bunch-stranded conductor and the thin-wall size-reduced elastomer insulating layer form a thin-wall size-reduced insulating conducting wire, the thin-wall size-reduced insulating conducting wire is classified and cabled, the middle core of the formed cable is a yellow/greenwire core, a flame-retardant belting layer is arranged outside the formed cable, a metal total shielding layer is arranged outside the flame-retardant belting layer, and a thin-wall size-reduced elastomer outer sheath layer is arranged outside the metal total shielding layer.

Description

technical field [0001] The invention relates to the technical field of electric wire and cable attachments for rail transit vehicles, in particular to a European standard reduced size rail transit vehicle control jumper flexible cable. Background technique [0002] In recent years, my country's urbanization process has gradually accelerated, the scale of cities and towns has continued to expand, and the problem of inter-city traffic congestion has become increasingly serious. my country's rail transit industry has developed rapidly. However, my country has a vast territory and a large population, and it is still difficult to find a travel ticket on site , the development of urban rail transit has become an inevitable choice to solve this problem. This year, my country's construction process is expected to reach 6,000 kilometers. By then, a total of 50 cities across the country will be involved in the planning of rail transit construction. The high-speed railways and subways...
