Abstract
The invention relates to a long-distance communication composite cable. The composite cable comprises a cable core and a protective layer covering the cable core. A low-frequency quad and a power line are arranged in the cable core, the protective layer is provided with a non-hygroscopicity insulating layer, a metal shielding layer, a lining layer, a steel tape armoring layer and an outer protective sleeve in sequence from inside to outside. The low-frequency quad is formed by intertwisting four single insulation cables of different colors, each single insulation cable is composed of a copper conductor and an insulating layer covering the periphery of the copper conductor. The power line is composed of an intertwisted conductor and an insulating layer covering the intertwisted conductor.
Description
Technical field
The present invention relates to a kind of cable, particularly a kind of long distance communication composite rope.
Background technology
Toll cable is mainly used in railway long distance or section communication circuit, can under electrified sections, power supply system of electric traction or forceful electric power disturbed condition, use.Along with the high speed development of the network information, need a large amount of transfer of data, the transmission of especially jumbo audio frequency, video information transmission and electric power.And, for prior art, as realized the transmission of above-mentioned information, that must lay multi-cable and could realize, this not only causes and lays environmental disorder, difficulty of construction increasing and difficult in maintenance, also the serious railway construction expense that increases.
Summary of the invention
The present invention seeks to the deficiency in order to overcome existing toll cable technology and a kind of long distance communication composite rope that integrates data message, audio-frequency information, video information and electric power transfer is provided.
For achieving the above object, the present invention solves the scheme that its technical problem takes and is:
This long distance communication composite rope, comprise cable core and be coated on the outer sheath of cable core, be provided with low frequency quad and power line in described cable core, described sheath is disposed with non-hygroscopic insulating barrier, metal screen layer, inner covering, steel-tape armouring layer and oversheath from the inside to the outside.
Further, described low frequency quad forms by the insulated single wire of four different colours is stranded, and described insulated single wire is comprised of copper conductor and the insulating barrier that is coated on the copper conductor periphery.
Closer, described power line is comprised of stranded conductor and the insulating barrier that is coated on the stranded conductor periphery.
Closer, described copper conductor is made by the soft circular copper wire of TR.
Closer, described stranded conductor forms by the monofilament of 49 0.25mm is stranded, and its nominal cross is 2.5mm
2.
Closer, described insulating barrier is polyolefin insulation.
Closer, described insulating barrier forms by " skin-bubble-Pi " three-layer co-extrusion physic foaming polyolefin.
Compared with prior art, usefulness of the present invention is: this long distance communication composite rope cable core adopts low frequency quad and power line combination, has realized that data message, audio-frequency information, video information and electric power transfer one cable can reach.Low frequency quad insulated single wire adopts " skin-bubble-Pi " three-layer co-extrusion physic foaming polyolefin insulation structure, has improved the insulation resistance of insulated single wire, has reduced sending allowance.Power line adopts the flexible conductor lay configuration, and the light softness of cable is easy to construction; Select polyolefine material to be used as the insulating barrier of insulated single wire and power line, make cable there is excellent ageing-resistant performance and mechanical strength, guarantee electric stability and the moisture resistance of insulation system; At cable core outer cladding non-hygroscopic insulating barrier, metal screen layer, inner covering, steel-tape armouring layer and oversheath, can improve humidity resistance, shielding properties and the mechanical and physical performance of cable, cable transmission performance is stable, and reliability is high.
the accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further described.
