Abstract
A high-rate signal cable used in rail traffic comprises a core, a core belting layer and an outer sheath, a shielding layer and a water-proof insulating layer are arranged outside a four-line conductor in the core and a double-faced plastic-aluminum composite ribbon layer, an integrated sheath layer, an aluminum sheath layer, a hot melt coating layer and an armored layer are arranged outside the core, thereby reinforcing the shielding and humidity resistance performance of the utility model and satisfying the utilizing requirement of high-rate transmission and humid area environment of the signal.
Description
Technical field
The utility model relates to a kind of digital signal cable, belongs to the cable technology field.
Background technology
Do not have screen in the surrounding layer in four lines in the existing digital signal cable cable core, between Lanzhou and Xinjiang and oversheath, do not have good shielding and moistureproof stop water yet, thereby can not be satisfactory aspect signal high-speed transfer, shielding properties and humidity resistance.
The utility model content
In order to overcome the deficiency of existing digital signal cable, the utility model provides a kind of track traffic two-forty signal cable, and it has the good characteristics of excellent, the moistureproof block-water effect of shielding properties.
The track traffic that the utility model provides two-forty signal cable.Comprise cable core and cable core belting layer, oversheath, be provided with several quads in the cable core, outside quad, be surrounded by and prick layer, belting layer, outside the belting layer of quad, coat screen and waterproof insulating layer.
In order to strengthen shielding of the present utility model and humidity resistance, between cable core belting layer and oversheath, set gradually two-sided plastic-aluminum combined belt, composite sheath layer, aluminium sheath layer, PUR coat, inner covering, armour.
For the screen that guarantees quad of the present utility model has reliable and stable shielding properties in cable laying construction and long-term the use, a current drainage lead is set in screen.
Quad of the present utility model is provided with screen and waterproof insulating layer outward, two-sided plastic-aluminum combined belt and composite sheath layer, aluminium sheath layer, PUR coat, armour are set outside cable core so have strengthened shielding of the present utility model and humidity resistance, can satisfy the instructions for use in signal high-speed transfer, humid environment zone.
Description of drawings
Fig. 1 is the utility model cross sectional representation.
In Fig. 1,1, the current drainage lead, 2, the insulating barrier of quad conductor, 3, the conductor of quad, 4, quad, 5, prick layer, 6, belting layer, 7, screen, 8, waterproof insulating layer, 9, cable core, 10, oversheath, 11, armour, 12 inner coverings, 13, the PUR coat, 14, the aluminium sheath layer, 15, composite sheath layer, 16, two-sided plastic-aluminum combined belt, 17, the cable core belting layer.
Embodiment
The screen 7 of quad 4 adopts the vertical bag of copper strips embossing, and its appearance extrusion molding one hdpe layer is as waterproof insulating layer 8; With one or more quad 4 stranded cable cores 9 of making, outside the belting layer 17 of cable core 9, coat two-sided plastic-aluminum combined belt 16 back extrusion molding sheaths and make composite sheath layer 15; Adopt argon arc welding equipment welding metallized aluminum restrictive coating 14 and carry out PUR to apply, both aluminium sheath layer 14 was played the sealing moisture-proof role, the inner covering of extruding 12 is had good cementation on its surface; Adopt double-deck galvanized steel strip to coat armour 11 in inner covering 12 outsides, coat outer jacket 10 at last.
Claims (3)
1, a kind of track traffic two-forty signal cable, comprise cable core and cable core belting layer, oversheath, be provided with several four lines conductor groups in the cable core, outside four line conductor groups, be surrounded by and prick layer, belting layer, it is characterized in that the belting layer of four line conductor groups coats screen and waterproof insulating layer outward.
