Abstract
The invention relates to a steel-tape longitudinally-wrapped railway digital signal cable which comprises a cable core with a wire group and an outer sheath thereof, wherein an inner lining layer and a steel tape armoring layer with a corrugated steel tape longitudinal wrapping structure are arranged between the cable core and the outer sheath in sequence. The invention has the advantages of high tensile strength, good bending resistance, low consumption of steel tapes, less working procedure, high production speed and low manufacturing cost.
Description
Technical field
The present invention relates to a kind of telecommunication cable, especially the digital signal cable of railway systems use.
Background technology
Existing railway digital signal cable is owing to use material and the deficiency of configuration aspects existence, and its tensile strength, bending resistance were difficult to adapt to instructions for use when cable was used in railway systems, and sensitive for damages causes communication failure.
Summary of the invention
In order to overcome the deficiency of existing railway digital signal cable, the invention provides a kind of steel-tape longitudinally-wrapped railway digital signal cable, have advantages of higher tensile strength and bending resistance preferably, can adapt to the instructions for use in railway systems.
Steel-tape longitudinally-wrapped railway digital signal cable provided by the invention comprises the cable core and the oversheath thereof that contain the lead group, is provided with inner covering successively and adopts the embossing steel band to indulge the steel-tape armouring layer of pack arrangement between cable core and oversheath.
The invention has the beneficial effects as follows: tensile strength and bending resistance are good, and the steel band consumption is few, and speed of production is fast, low cost of manufacture.
Description of drawings
Fig. 1 is a longitudinal section of the present invention schematic diagram, and Fig. 2 is a cross sectional representation of the present invention.
In Fig. 1, Fig. 2,1, the steel-tape armouring layer, 2, cable core, 3, inner covering, 4, oversheath, 5, lead, 6, the lead group.
Embodiment
With reference to Fig. 1, Fig. 2, make when of the present invention, several lead group 6 stranded cable cores 2 of making that to form by lead 5 at first, outside cable core 2, coat the inner covering of making by polyethylene 3 then, use again through the vertical coated steel band armour 1 outside inner covering 3 of the galvanized steel strip behind the embossing, adopt cable jacket material to coat oversheath 4 at last, promptly make the present invention.
