Abstract
The present invention is disclosed including two groups of star-like twisted cores, the core includes the insulating layer for being located at several conductors at middle part and being wrapped on the outside of several conductors jointly, it is surrounded with waterstop jointly on the outside of two groups of star-like twisted cores and constitutes cable core, water blocking yarn is filled between several core gaps in cable core, separation layer, composite shielding layer are successively wrapped up outside cable core, composite shielding layer is wrapped with armor, and the outer extrusion moulding of armor has restrictive coating, and the restrictive coating is coated with waterproof layer.Cable core intensity of the invention is high, is less prone to disconnected core, while having softness well, this outer cable has high-low temperature resistant, tear-resistant, wear-resisting, waterproof, shielding and bending features performance well.
Description
Technical field
The present invention relates to cable, specifically a kind of rail traffic special-purpose water-proof cable.
Background technique
Cable is usually the cable of similar rope as several or made of several groups of wire strandings, between every group of conducting wire mutually absolutely
Edge, and be often twisted into around a center, entire outside is surrounded by the coating of high-insulation.Multi rack is located at aerial or is mounted in ground
Under, it is water-bed, be used for telecommunication or power Transmission.Cable can be divided into power cable, communication cable and control cable etc. by its purposes.With
The fast development of power industry, data communication industry, urban track traffic industry etc., requirement of all trades and professions to cable is increasingly
Height will not only avoid cable from being mechanically damaged, insulation harm, insulation ag(e)ing are rotten etc. in use, also to avoid insulation by
Tide, i.e. waterproof.
In general, cable, which is often laid in, ground or has the place of water, due to the permeability of cable sheath material, or
Person's cable cover(ing) is entered inside cable by mechanical damage, water, leads to the interior formation water tree that insulate, and water tree is constantly aoxidized, made
The destruction insulated in pairs, this substantially reduces the service life of cable.
Summary of the invention
The purpose of the present invention is to provide a kind of rail traffic special-purpose water-proof cables, to solve to propose in above-mentioned background technique
The problem of.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that：
A kind of rail traffic special-purpose water-proof cable, including two groups of star-like twisted cores, the core includes being located at middle part
Several conductors and the insulating layer that is wrapped on the outside of several conductors jointly, on the outside of two groups of star-like twisted cores together about
Be surrounded by waterstop and constitute cable core, water blocking yarn is filled between several core gaps in cable core, successively wrapped up outside cable core separation layer,
Composite shielding layer, composite shielding layer are wrapped with armor, and the outer extrusion moulding of armor has restrictive coating, the restrictive coating outer cladding
There is waterproof layer.
Further, the insulating layer uses material for low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.
Further, the restrictive coating uses nylon material.
Further, the separation layer is overlapped wrapped composition using high temperature resistance polyester band, and wrapped overlap rate is not less than 25%.
The beneficial effects of the invention are as follows：
Structure of the invention provides a kind of rail traffic special-purpose water-proof cable, and the coat layer of power cable is made of nylon sheath wire,
Stronger wear-resisting property can effectively avoid causing cable fault because of friction, and can effectively prevent longitudinal infiltration of cable, prevent
Conductor is oxidized, and guarantees the electrical resistance of conductor, is conducive to the waterproof performance for improving cable, is extended the service life of cable, expands
The use scope of cable increases the utilization rate of cable.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is schematic structural view of the invention.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, the present invention provides a kind of rail traffic special-purpose water-proof cable, including two groups of star-like twisted cores 1,
The core 1 includes the insulating layer 1- for being located at several conductor 1-1 at middle part and being wrapped on the outside of several conductor 1-1 jointly
2, two groups of star-like 1 outsides of twisted cores are surrounded with waterstop 2 jointly and constitute cable core, between 1 gap of several cores in cable core
Filled with water blocking yarn 3, separation layer 4, composite shielding layer 5 are successively wrapped up outside cable core, composite shielding layer 5 is wrapped with armor 6, armour
The dress outer extrusion moulding of layer 6 has restrictive coating 7, and the restrictive coating 7 is coated with waterproof layer 8.
The insulating layer 1-2 uses material for low-smoke non-halogen flame-retardant cross-linking radiation polyolefin.
The restrictive coating 7 uses nylon material.
The separation layer 4 is overlapped wrapped composition using high temperature resistance polyester band, and wrapped overlap rate is not less than 25%.
The embodiments of the present invention described above are not intended to limit the scope of the present invention, any in the present invention
Spirit and principle within made modifications, equivalent substitutions and improvements etc., should be included in claim protection model of the invention
Within enclosing.
