Abstract
The utility model discloses a flexible cable for the railway locomotive, which comprises a conductor; the conductor is stranded with tinned special soft copper wire of six types; and the outside of the conduct is provided with a polyester film, and the polyester film is coated with an insulation layer. The flexible cable for the railway locomotive has the advantages of good physical mechanical property and excellent high temperature resistant performance, and not only is the product of low smoke zero halogen, but also is provided with green environmental protection, therefore meeting the green environmental protection and resource saving requirements.
Description
Technical field:
The utility model relates generally to a kind of cable, especially a kind of rail vehicles flexible cable.
Background technology:
At present, illuminations such as subway, track, railway, cable car both at home and abroad, air-conditioning, signal, electric power require more and more higher with the used for rolling stock cable, promptly require cable to have excellent softness, require again to have high heat-resisting quantity and have the environmental protection performance.Under the situation of this contradiction, the locomotive cable of prior art not exclusively adapts to development of times.At present domestic also do not have technology can improve the resistance to ag(e)ing of rail vehicles with cable, and can not improve current-carrying capacity of cable, energy savings, the technology of environmental protection.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of rail vehicles flexible cable to be provided.It possesses characteristics such as anti-150 ℃ of high-temperature behaviors, oil resistance, green environmental protection, high flexibility, bending property and life-span length.
The utility model is achieved through the following technical solutions:
The rail vehicles flexible cable includes conductor, it is characterized in that described conductor by the special soft copper tow strand of zinc-plated six classes, and conductor has laminated polyester film outward, and laminated polyester film has insulating barrier outward.
Described rail vehicles flexible cable, the bundle twisting pitch multiple that it is characterized in that described conductor is not more than 14 times of conductor diameter.
Described polyester film has good physical and mechanical properties and insulation electrical performance; The material that described insulating barrier adopts is,
Described conductor adopts the special soft copper silk of zinc-plated six classes, in bundle strand production technology, restraints innings multiple that tangles and is not more than 14 times that restraint the strand conductor diameter, thereby guaranteed the cable conductor rounding, external diameter is little, the conductance height, characteristics such as flexibility is good have improved the temperature resistant grade and the crooked serviceability of cable.The utility model adopts polyester film, has improved the insulation electrical performance of cable and the adhesion and the damage of protection insulation and conductor; Insulating layer material adopts high temperature resistant 150 ℃ of crosslinked rubber environmental protection CABLE MATERIALS, this CABLE MATERIALS not leaded and lead compound, mercury and mercury compound cadmium, chromium and compound thereof and Cr VI bromo-ether compounds, have outstanding high temperature resistance and be environmental protection, guarantee that also the present utility model cable has good low cigarette, Halogen, fire-retardant, oil resistant, physical mechanical, performance such as electric.
The utility model has the advantages that:
The utlity model has good physical and mechanical properties and superior resistance to elevated temperatures, be not only the low smoke and zero halogen product, possess environment protection requirement especially, the requirement that meet environmental protection, economizes on resources.
Description of drawings:
Accompanying drawing is a schematic cross-section of the present utility model.
Embodiment:
The rail vehicles flexible cable includes conductor 1, and conductor 1 has laminated polyester film 2 by the special soft copper tow strand of zinc-plated six classes outside the conductor 1, insulating barrier 3 is arranged outside the laminated polyester film 2.The bundle twisting pitch multiple of conductor 1 is not more than 14 times of conductor 1 external diameter.
Claims (2)
1, the rail vehicles flexible cable includes conductor, it is characterized in that described conductor by the special soft copper tow strand of zinc-plated six classes, and conductor has laminated polyester film outward, and laminated polyester film has insulating barrier outward.
2, rail vehicles flexible cable according to claim 1, the bundle twisting pitch multiple that it is characterized in that described conductor is not more than 14 times of conductor diameter.
