At present, known common railroad coach cable, overall weight weight, size is large, and tensile strength is low, electrical property and physical and mechanical properties poor, cable security poor performance, does not meet the lightweight requirements of high ferro motor-car, cannot ensure the safe operation of railroad coach.And, common railroad coach cable adopts Halogen insulated with material layer, restrictive coating, once breaking out of fire, halogen produces a large amount of dense smoke, make rescue work be difficult to carry out, personnel are scorched to death immediately, cause to be smoked by smog and suffocate, these shortcomings and technical problem limit the use of product, cause the safe operation hidden danger of railroad coach.
Summary of the invention
The utility model provides a kind of railroad coach low smoke and zero halogen thin-walled cable for solving in known technology the technical problem that exists.
The purpose of this utility model is to provide one, and to have tensile strength high, whole cable is lightweight, size is less, electrical property and physical and mechanical properties high, cable security performance is high, meet the lightweight requirements of high ferro motor-car, ensure the safe operation of railroad coach, the railroad coach low smoke and zero halogen thin-walled cable of the features such as severe installation and environment for use can be adapted to.
The utility model cable is mainly the supporting electric wire of railroad coach, is suitable for railroad coach transferring electric power or transmission of signal uses.This cable has Halogen, low cigarette, fire-retardant, resistance to scraped finish, tension, resistance to wet goods performance; The bulk shape size of cable is less, saves installing space.
The characteristic had of the utility model railroad coach low smoke and zero halogen thin-walled cable:
1. conductor is stranded tinned conductor, when stranded, add high strength fibre.
2. insulation adopts cross-linking radiation heatproof 105 DEG C of polyolefine materials, ensures thin-walled performance requirement.
3. sheath adopts cross-linking radiation heatproof 105 DEG C of polyolefine materials, makes cable have the performances such as Halogen, low cigarette, fire-retardant, oil resistant, resistance to scraped finish, softness, can adapt to harsher install and use environment.
The technical scheme that the utility model railroad coach low smoke and zero halogen thin-walled cable is taked is:
A kind of railroad coach low smoke and zero halogen thin-walled cable, is characterized in that: railroad coach low smoke and zero halogen thin-walled cable is made up of insulated wire cores, lapping layer and restrictive coating; Insulated wire cores is made up of twisted copper conductors and insulating barrier, has reinforcing fibre silk in stranded conductor, and together with stranded conductor and the conjunction of reinforcing fibre skein silk deflect, insulating barrier is extruded in outside, is provided with filling between the lapping layer in insulating barrier and outside, is restrictive coating outside lapping layer.
The utility model railroad coach low smoke and zero halogen thin-walled cable can also adopt following technical scheme:
Described railroad coach low smoke and zero halogen thin-walled cable, is characterized in: reinforcing fibre silk is 3-10 root, rounded frame mode arrangement in stranded conductor.
Described railroad coach low smoke and zero halogen thin-walled cable, is characterized in: railroad coach low smoke and zero halogen thin-walled cable cross section 0.5 ~ 2.5mm
2, insulated wire cores 2 core ~ 24 core.
The advantage that the utility model has and good effect are:
Railroad coach low smoke and zero halogen thin-walled cable, owing to have employed the brand-new technical scheme of the utility model, compared with prior art, adds reinforcing fibre silk while reducing external diameter during the utility model conductor strand, improves tensile strength; The structural design optimized, reduces whole cable weight and improves cable security performance simultaneously; The utility model has excellent electrical property and physical and mechanical properties, and whole cable is lightweight, and size is less, meets the lightweight requirements of high ferro motor-car, ensures the safe operation of railroad coach; In addition, this cable also has Halogen, low cigarette, fire-retardant, resistance to scraped finish, oil resistant, can adapt to the advantages such as severe installation and environment for use.

Embodiment
For utility model content of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Accompanying drawings 1.
Embodiment 1
A kind of railroad coach low smoke and zero halogen thin-walled cable, is made up of insulated wire cores, lapping layer 5 and restrictive coating 6; Insulated wire cores is made up of twisted copper conductors 2 and insulating barrier 4, have reinforcing fibre silk 3 in stranded conductor 2, stranded conductor 2 with reinforcing fibre silk 3 is stranded deflect together with, insulating barrier 4 is extruded in outside, being provided with filling 1 between the lapping layer 5 in insulating barrier 4 and outside, is restrictive coating 3 outside lapping layer 5.Cross-section of cable 2.5mm
2, insulated wire cores is 2 cores.The rounded frame mode arrangement in stranded conductor 2 of 6 reinforcing fibre silks, 3,6 reinforcing fibre silks 3 is had in each root insulated wire cores.
The present embodiment railroad coach low smoke and zero halogen thin-walled cable rated voltage: 300/500V.
The specific implementation process of the present embodiment and feature:
1. conductor is stranded tinned conductor, when stranded, add high strength fibre.
2. insulation adopts cross-linking radiation heatproof 105 DEG C of polyolefine materials, ensures thin-walled performance requirement.
3. sheath adopts cross-linking radiation heatproof 105 DEG C of polyolefine materials, makes cable have the performances such as Halogen, low cigarette, fire-retardant, oil resistant, resistance to scraped finish, softness, can adapt to harsher install and use environment.
After the present embodiment railroad coach low smoke and zero halogen thin-walled cable adopts this structure, make this cable have excellent electrical property and physical and mechanical properties, thinwalled insulation and jacket structure, make the whole cable weight of same cross-sectional lighter, size is less, meets the lightweight requirements of high ferro motor-car; Special conductor structure greatly improves the tensile strength of core after wiring, ensures the safe operation of railroad coach; In addition, this cable also has Halogen, low cigarette, fire-retardant, resistance to scraped finish, resistance to wet goods characteristic, can adapt to severe installation and environment for use.
