Abstract
The utility model relates to a termite preventing railway signal cable. The colors of insulated wire cores (1) are red, green, white, and blue and conform to the Munsell color scale, a second core or a fourth core are twisted together as a group according to definite colors and pitch lengths, and color separation binding belts (2) with different colors are respectively dredged and wound. Finally, comprehensive twisting is carried out, and after the comprehensive twisting, a winding and wrapping belt (3) is arranged for tight binding. To the termite preventing railway signal cable without shields, the outer face of the winging and wrapping belt (3) is successively provided with an inner protective jacket (7), steel belt armor (8), and a termite protecting outer protective jacket (9). To the termite preventing railway signal cable with a shield, the outer face of the winging and wrapping belt (3) is provided with an aluminium plastic shield (4), and an inner protective jacket (7) made of polyethylene, or the outer face of the winging and wrapping belt (3) is provided with an isolating jacket (5) made of polyethylene, an argon arc welding aluminum protective jacket (6), an inner protective jacket (7) made of polyethylene, and the outer face of the inner protective jacket (7) made of polyethylene is provided with steel belt armor (8), and a termite protecting outer protective jacket (9).
Description
The utility model is a kind of termite-proof railway signal cable.Belong to the cable technology field.
At present, known railway signal cable is because of possessing termite-proof function, when being used in intensive regional of termite activity, can be subjected to the infringement of termite.
The utility model provides and a kind ofly prevents that termite from biting, the railway signal cable of mouse bite preventing, is used for the intensive area of termite activity, prevents to be subjected in the railway signal cable use infringement of termite or mouse.The technical solution of the utility model:
Insulated wire cores (1) is that diameter is the single naked annealed copper wire of 1.0mm, outer bread insulating material of polyethylene constitutes, color is red, green, white, blue, meet Munsell colour scale, be twisted into one group by two cores or four-core according to certain color and pitch then, dredge color separation band (2) respectively, comprehensively kink at last, twining package tape (3) is set after comprehensively kinking tightens around different colours.
Not with the termite-proof railway signal cable of shielding, twining package tape (3) outside sets gradually polyethylene inner sheath (7), steel-tape armouring (8), termite-proof oversheath (9) for common.
For shielded termite-proof railway signal cable, twining package tape (3) outside shielding construction has two kinds of forms: twining package tape (3) outside is provided with aluminium-plastic tape shielding (4), polyethylene inner sheath (7) or polyethylene separation sleeve (5) is set in twining package tape (3) outside, argon arc welding aluminium sheath (6), polyethylene inner sheath (7).Polyethylene inner sheath (7) outside is provided with steel-tape armouring (8), termite-proof oversheath (9).
Figure of description is a structure chart of the present utility model.
The advantage of the utility model White ant prevention railway signal cable provides and a kind ofly prevents that termite from gnawing Sting, the railway signal cable of mouse bite preventing, be used for the intensive area of termite activity, prevent railway Be subjected to the infringement of termite or mouse in the signal cable use procedure.
Claims (1)
1, a kind of termite-proof railway signal cable, it is characterized in that: insulated wire cores (1) is in groups stranded by two cores or four-core, dredge color separation band (2) respectively around different colours, comprehensively kink at last, twining package tape (3) is set after comprehensively kinking to be tightened, for not with the structure of metallic shield, twining package tape (3) outside sets gradually polyethylene inner sheath (7), steel-tape armouring (8), termite-proof oversheath (9) is for the structure of band shielding, twining package tape (3) outside sets gradually aluminium-plastic tape shielding (4), polyethylene inner sheath (7), steel-tape armouring (8), termite-proof oversheath (9) or set gradually polyethylene separation sleeve (5) in twining package tape (3) outside; Argon arc welding aluminium sheath (6), polyethylene inner sheath (7), steel-tape armouring (8), termite-proof oversheath (9).
