Abstract
The invention relates to a dampproof communication cable which comprises a jacket, a cable core and a dry water-blocking tape. The cable core is located in the jacket. The dry water-blocking tape is located in the jacket and is wound around the outer surface of the cable core. According to the dampproof communication cable, the dry water-blocking tape is wound around the outer surface of the cable core to prevent the cable core from being affected with damp and water from entering the cable core; due to the fact that the winding process of the dry water-blocking tape is much easier than the coating process of waterproof cream, production efficiency of the dampproof communication cable can be improved, and cost of the dampproof communication cable can be reduced.

In above-mentioned moistureproof telecommunication cable, preferably, described cable core comprises telephone communication cable and voice-over-net cable, described telephone communication cable comprises the first wire and the first insulating barrier, described the first insulating barrier is coated on the outside of described the first wire, and described the first wire is copper covered steel wire, and described voice-over-net cable comprises the second wire and the second insulating barrier, described the second insulating barrier is coated on the outside of described the second wire, and described the second wire is copper conductor.
In above-mentioned moistureproof telecommunication cable, preferably, described cable core comprises two groups of telephone communication cables and two group network voice cables, every group of telephone communication cable comprises two mutual stranded telephone communication cables, every group network voice cable comprises two mutual stranded voice-over-net cables, interval predeterminable range between every group of telephone communication cable and every group network voice cable.
In above-mentioned moistureproof telecommunication cable, preferably, the cross section of described cable core is rounded, and described two groups of telephone communication cables and two group network voice cables are evenly distributed on the center of circle taking described cable core on the same circumference in the center of circle.
In above-mentioned moistureproof telecommunication cable, preferably, described sheath, the first insulating barrier and the second insulating barrier are made by high density polyethylene (HDPE).
In above-mentioned moistureproof telecommunication cable, preferably, in described sheath, be also provided with and tear rope, described in tear the contiguous described sheath of rope.
In above-mentioned moistureproof telecommunication cable, preferably, the external diameter of described the first wire is less than the external diameter of described the second wire, and the external diameter of described the first insulating barrier is less than the external diameter of described the second insulating barrier.
In above-mentioned moistureproof telecommunication cable, preferably, described moistureproof telecommunication cable comprises two described dry type waterstops, and described two dry type waterstops are alternately wrapped in the outer surface of described cable core.
Moistureproof telecommunication cable of the present invention, blocking water to bring by the outer surface winding dry type at cable core prevents that cable core from making moist into water.Because the technique of winding dry type waterstop is simply more a lot of than the technique that is coated with waterproof, therefore can improve the production efficiency of moistureproof telecommunication cable, reduce the cost of moistureproof telecommunication cable.
Brief description of the drawings
Fig. 1 is the structural representation of moistureproof telecommunication cable of the present invention.
