Abstract
The utility model relates to the technical field of cable, in particular to a railway control cable which is suitable for being used under the fields with bad conditions like an altiplano for a long period; the cable includes a conductor, an insulating layer, a shielding layer and a jacket layer; the insulating layer is coated outside the conductor; besides, a plurality of conductors coating the insulating layer after being intertwisted into a cable is covered by the shielding layer; the jacket layer is arranged outside the shielding layer; a layer of cotton paper zone is arranged between the shielding layer and the jacket layer. The cable effectively solves the problem that the cable is used for a long period under the fields with bad conditions and the cable can be used as a monitoring cable along the Qinghai-Tibet Railway.
Description
Technical field
The utility model relates to the cable technology field, refers in particular to a kind of open-air long-term railway control cable of using that is applicable to mal-conditions such as plateau.
Background technology
4500 meters of Qinghai-Tibet Railway mean sea levels, high and cold, day and night temperature is big, ultraviolet radiation is strong, some area also has frequent strong thunder and lightning, and open-air installation exercise difficulty is big.Cable uses under this harsh climate condition, must possess following performance:
1, long-term work temperature is-40 ℃; Air pressure environment: 544mb～1000mb;
2, have anti-plateau intensive ultraviolet function, and tool is anti-interference and lightning protection electric work energy;
3, it is big to be suitable for day and night temperature, and has wind resistance and blow the rowization function;
4, rated voltage: 300/500V;
5, the anti-general acid of cable, alkali, ozone;
6, cable-40 ℃ of environment and more than, easy to install.
At present domestic all kinds of cables also do not have a kind of cable to adapt to the adverse circumstances on plateaus such as Qinghai-Tibet Railway fully, and common cable used less than three months, then occur drawing up etc. and send a telegraph cable and can not use fully.
Summary of the invention
The technical problem that the utility model solves be to provide a kind of can be under plateau adverse weather conditions such as Qinghai-Tibet Railway, the open-air long-term railway control cable of using.
The technical problem that the utility model solves is achieved by the following technical solution: comprise conductor, insulating barrier, screen and restrictive coating; Conductor outer wrapping insulating barrier, and be coated with screen behind the stranded stranding of the conductor of some wrap insulate layers; Screen is provided with restrictive coating outward; Be provided with one deck cotton paper band between screen and restrictive coating.
Described cotton paper band vertically being wrapped in outside the screen by cable.
Described insulating barrier and restrictive coating are the elastomers of making based on the composite material of ethylene-propylene diene copolymer.
Be enclosed with three conductors in the described screen.
The utility model is by being provided with the cotton paper band between screen and restrictive coating, it is after main elastic composite is made, in conjunction with screen that insulating barrier and restrictive coating adopt ethylene-propylene diene copolymer; Make cable of the present utility model can reach or have following performance:
1, cable long-term work temperature :-45 ℃～+ 70 ℃ (minimum serviceability temperature-60 ℃); Can under air pressure: 544mb～1000mb condition, work.
2, rated voltage: 300/500V.
3, cable has the ultraviolet ray of anti-plateau, and the wind cracking function under the adverse weather condition of plateau.
4, through examination, test exchanging 50Hz, do not puncture under the 2000V/5min voltage.
5, insulation and sheath material tensile strength: 〉=7.2Mpa.
6, insulation and sheath material elongation at break: 〉=150%.
7, the anti-general acid of cable, alkali, anti-ozone.
8, the anti-thunder and lightning of cable tool interference free performance.
9, cable still can keep elasticity, flexibility preferably under low temperature-50 ℃ environment.
Thereby make the utility model cable long-term applicable to the field under the adverse weather condition of plateau; It is along the line to can be used for Qinghai-Tibet Railway, uses as a kind of monitoring cable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Accompanying drawing is the utility model cable cross-sectional configuration schematic diagram.
The explanation of accompanying drawing figure number
Conductor 1 insulating barrier 2
Screen 3 cotton paper bands 4
Restrictive coating 5
Embodiment
See accompanying drawing, cable of the present utility model comprises conductor 1, insulating barrier 2, screen 3, cotton paper band 4 and restrictive coating 5; Conductor 1 outer wrapping insulating barrier 2; And, be coated with screen 3. screens 3 outer vertical parcel cotton paper bands 4 behind the conductor 1 stranded stranding of some (mainly be three, also can be many) wrap insulate layer 2 by cable; The tissue paper layer 4 outer restrictive coating 5 that is provided with.Aforementioned dielectric layer 2 and restrictive coating 5 are that main composite material is made by ethylene-propylene diene copolymer; Make that insulating barrier 2 and restrictive coating 5 are an elastomer.
With upper conductor 1 is the tin-coated copper conductor; Screen 3 is by the tinned copper wire braiding, and this screen 3 makes cable have anti-thunder and lightning and anti-interference function.
