Description
Technical field
This utility model relates to a kind of electric wire, particularly relates to the extraordinary direct current cables of a kind of novel rail.
Background technology
Railway is the large artery trunks of Chinese national economy and social development, and railway is in China five big traffic means of transportation
Space of top prominence.With the even sea-freight of aircraft, automobile with mass energy realize transport purpose compared with, electric railway has more sustainable
Property and the value of environmental protection.From traditional theory, railway unit transport energy consumption is far below highway and civil aviaton, by transporting other
Effective replacement of mode, it is possible to the overall energy consumption of transportation is greatly reduced.Therefore, railway transportation is the transport of low-carbon environment-friendly
Mode, best suits the worldwide trend of energy-saving and emission-reduction instantly.
In the past, the railway of China is based on diesel locomotive group, in the electric wire used in the railway system and control system
Electric wire technology less demanding, oil resistant and fire resistance, less Gu are mainly considered with regard to this most internal electric wire of locomotive
And the requirement in environmental protection, configuration density and physical dimension.In the recent period, along with EMUs and the development of high-speed railway, advanced abroad
The introducing of technology, the safety consciousness of people further improves, and has higher requirement electric wire: not only require electric wire
Cable has an oil resistant, fire-retardant, and has high mechanical properties, asepsis environment-protecting, more compact in physical dimension.The Ministry of Railways is the clearest and the most definite
The electric wire used for rolling stock of novel environment friendly must be used in novel railway locomotive, and put into effect corresponding product technology
Specification, and for the electric wire used for rolling stock of novel environment friendly also will be progressively promoted in the production of old vehicle and maintenance process,
Its main representative products is low smoke and zero halogen irradiation crosslinked polyolefin insulating electric wire." 13 " period, the machine of the railway system
Car vehicle cable is among update, and the construction of the railway network brings fabulous opportunity, railway to wires and cables industry
Special cable substantial amounts of, with high content of technology, special is badly in need of in building of net.
Utility model content
The purpose of this utility model be provide one have environmental protection, Halogen, low cigarette, fire-retardant A class, block water, waterproof, anti-
The extraordinary direct current cables of the track traffic of the performances such as Mus, termite-proof, nontoxic, UV resistant, compact conformation.
The technical solution of the utility model is: described cable includes the copper conductor stranded by some copper wires, described copper
Gap uniformity between conductor copper wire is coated with waterproof paste and water-proofing powder complex, closely extrudes irradiation outside described copper conductor
Crosslinked polyetylene insulated layer, the outer wrapped double-deck environment-protecting type high-flame-retardanthalogen-free halogen-free belting layer of described insulating barrier, described environment-friendly high fire-retardant
One layer of aluminium-plastic tape of vertical bag and halogen-free polyolefin comprehensive waterproof sheath outside Halogen belting layer, described comprehensive waterproof sheath is outer wrapped
Double-deck halogen-free high flame-retardant glass belt, extrudes protection against rodents Anti-termite flame-retardant polyolefin complex outside described halogen-free high flame-retardant glass belt
Oversheath.
This utility model compared with prior art has the advantage that
1, this utility model uses water-blocking conductor, is provided with aluminum-poly-comprehensive waterproof sheath, makes product have the radial direction of excellence
With longitudinal water resistance.
2, this utility model is provided with double-deck environment-protecting type high-flame-retardanthalogen-free halogen-free belting layer outside insulating barrier, and integrated sheath is outer wrapped
Double-deck halogen-free high flame-retardant glass belt, extrude protection against rodents Anti-termite flame-retardant polyolefin complex oversheath, improve the fire-retardant of product
Performance.
3, this utility model uses IXPE insulating barrier, improves the electrical property of product, mechanical performance and resistance to
Warm nature energy.
4, this utility model extrudes protection against rodents Anti-termite flame-retardant polyolefin complex oversheath, makes product have the anti-life of excellence
Thing harm performance and fire resistance.
5, the material that this utility model uses all belongs to low smoke, zero halogen environment-friendly materials, meet the environmental regulation of ROHS and REAOH
Regulation, beneficially product is gone abroad.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is copper conductor, and 2 is insulating barrier, and 3 is high-flame-retardanthalogen-free halogen-free belting layer, and 4 is comprehensive waterproof sheath, and 5 is that Halogen is high
Flame-proof glass fibre belt, 6 is protection against rodents Anti-termite flame-retardant polyolefin complex oversheath.
Detailed description of the invention
A kind of novel rail special type direct current cables, described cable includes the copper conductor stranded by some copper wires
1, the gap uniformity between the internal copper wire of described copper conductor 1 is coated with waterproof paste and water-proofing powder complex, and described copper conductor 1 is outer tight
The close IXPE insulating barrier 2 that extrudes, the described outer wrapped double-deck environment-protecting type high-flame-retardanthalogen-free halogen-free belting layer 3 of insulating barrier 2, described
Environment-friendly high fire-retardant Halogen belting layer 3 one layer of aluminium-plastic tape of outer vertical bag and halogen-free polyolefin comprehensive waterproof sheath 4, described comprehensively
