Abstract
The utility model discloses a high communication cable with high water seepage resistant performance, comprising a cable core wire, a shielding layer, a wrapping band layer, a water blocking band layer and a jacket layer; and the wrapping band layer, the water blocking band layer, the shielding layer and the jacket layer are sequentially wrapped outside the cable core wire from inside to outside. The water blocking band layer disclosed by the utility model is wrapped outside the wrapping band layer to guarantee the firm fit between the cable core wire and the shielding layer, so that the longitudinal wrapping effect is good, the water seepage property can be guaranteed, and the outline of the cable meets the demands; the transverse and longitudinal water blocking property of the communication cable with the high water seepage resistant performance is also guaranteed; and furthermore, the communication cable with the high water seepage resistant performance, disclosed by the utility model, is provided with the shielding layer, so that the shielding effect of the cable is further improved and the application performance of the cable is improved.
Description
Technical field
The utility model belongs to digital communication and transmits carrier scope, particularly a kind of high impervious water telecommunication cable.
Background technology
The water permeability resistance of former telecommunication cable can normally pass through the cable core factice for filling, also adopts ointment to fill between cable core and the screen, guarantees permeability performance.But owing to there are phenomenons such as the ointment filling is inhomogeneous, accumulation, interval, cause permeability performance unstable, jacket surface plays adverse consequencess such as bulge, brings very big hidden danger to product quality.
The utility model content
The utility model technical problem to be solved provides a kind of high impervious water telecommunication cable, makes between cable core and the screen to closely cooperate, and vertical bag is effective.
The technical scheme of the utility model is following:
A kind of high impervious water telecommunication cable comprises: cable core, screen, belting layer, water blocking tape layer and restrictive coating; Said cable core is coated with said belting layer, said water blocking tape layer, said screen and said restrictive coating outward from inside to outside successively.
Further: said cable core comprise orderly arrangement to the line group, said the line group is comprised two mutual stranded insulated conductors; Said insulated conductor comprises conductor and insulating barrier, and said conductor is extruded with said insulating barrier outward.
Further: the evenly continuous petroleum jelly that is filled with between the said cable core and between said cable core and the said belting layer.
Further: said water blocking tape layer is an even wrapped two-sided waterstop outside said belting layer.
Further: said screen comprises aluminium-plastic tape and earth lead.
Further: said aluminium-plastic tape is wrapped outside said water blocking tape layer and said earth lead, and said water blocking tape layer and said earth lead are coated.
Further: said earth lead directly is placed on outside the said water blocking tape layer.
The technique effect of the utility model is following:
1, the water blocking tape layer of the utility model is coated on the belting layer outside, makes to closely cooperate between cable core and the screen, and vertical bag is effective, can guarantee that permeability performance and cable appearance meet the demands.
2, the utility model has guaranteed the horizontal and vertical block-water performance of high impervious water telecommunication cable.
3, the utlity model has screen, further improved the shield effectiveness of cable, improved the serviceability of cable.
