Abstract

The utility model relates to a telecommunication composite cable, and the cable comprises a cable core and a protection layer which wraps the cable core. The interior of the cable core is provided with a low-frequency quad and a power line. The protection layer is sequentially provided with a non-hygroscopic insulating layer, a metallic shielding layer, an inside liner, a steel-tape armouring layer and an outer sheath. The low-frequency quad is formed by the stranding of four insulating wires with different colors. Each insulating wire consists of a copper conductor and an insulating layer which wraps the copper conductor. The power line consists of a stranded conductor and an insulating layer which wraps the stranded conductor.

Description

Long distance communication composite rope
Technical field
The utility model 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, the also serious railway construction expense that increases.
Summary of the invention
The utility model object is 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 utility model solves the scheme that its technical problem takes and is:
This long distance communication composite rope, comprise cable core and be coated on the sheath outside cable core, in described cable core, be provided with low frequency quad and power line, 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 is by stranded the forming of insulated single wire of four different colours, and described insulated single wire is made up of copper conductor and the insulating barrier that is coated on copper conductor periphery.
Closer, described power line is made up of stranded conductor and the insulating barrier that is coated on stranded conductor periphery.
Closer, described copper conductor is made up of the soft circular copper wire of TR.
Closer, described stranded conductor is by stranded the forming of monofilament of 49 0.25mm, and its nominal cross is 2.5mm 2.
Closer, described insulating barrier is polyolefin insulation.
Compared with prior art, usefulness of the present utility model is: this long distance communication composite rope cable core adopts low frequency quad and power line combination, and having realized 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 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.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the utility model long distance communication composite rope structural representation.
In figure: 1, cable core; 2, low frequency quad; 3, power line; 4, insulated single wire; 5, copper conductor; 6,61, insulating barrier; 7, stranded conductor; 9, non-hygroscopic insulating barrier; 10, metal screen layer; 11, inner covering; 12, steel-tape armouring layer; 13, oversheath.
Embodiment
Below in conjunction with the drawings and the specific embodiments, the utility model is described in detail:
A kind of long distance communication composite rope shown in Fig. 1, comprise cable core 1 and be coated on the sheath outside cable core 1, in described cable core 1, be provided with low frequency quad 2 and power line 3, described sheath is disposed with non-hygroscopic insulating barrier 9, metal screen layer 10, inner covering 11, steel-tape armouring layer 12 and oversheath 13 from the inside to the outside.
Described low frequency quad 2 is by stranded the forming of insulated single wire 4 of four different colours, and described insulated single wire 4 is made up of copper conductor 5 and the insulating barrier 6 that is coated on copper conductor 5 peripheries.
Described power line 3 is made up of stranded conductor 7 and the insulating barrier 61 that is coated on stranded conductor 7 peripheries.
Described copper conductor 5 is made up of the soft circular copper wire of TR.
Described stranded conductor 7 is by stranded the forming of monofilament of 49 0.25mm, and its nominal cross is 2.5mm 2.
Described insulating barrier 61 is polyolefin insulation.
Described insulating barrier 6 forms by " skin-bubble-Pi " three-layer co-extrusion physic foaming polyolefin.
The long distance communication composite rope manufacturing process of above-described embodiment is as follows:
First, by stranded the insulated single wire of the four different colours 4 low frequency quad 2 of making, according to demand several low frequency quads 2 of having produced and power line 3 are utilized to the stranded cable core 1 of making of machine for making cable high-speedly together again, and coated non-hygroscopic insulating barrier 9, metal screen layer 10, inner covering 11, steel-tape armouring layer 12 and oversheath 13 make long distance communication composite rope of the present utility model successively outside cable core 1.
This long distance communication composite rope cable core adopts low frequency quad and power line combination, and having realized 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 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.
