Abstract
The utility model discloses a strenghthened type tensile cable that blocks water relates to cable technical field, has solved the technical problem that ordinary blocking water nature of cable is poor and the pull resistance is poor, the utility model discloses an article four, conductor and the the inner insulating layer of parcel the conductor outside are drawn together to the cable core line of fan -shaped equipartition, cable core solenoid, and the cable core line has set gradually outward, water blocking layer, inner sheath, armor, oversheath layer, is provided with the filling layer between water blocking layer and the inner sheath layer, is provided with enhancement cable core and four annex cable core lines of four edge circumference evenly distributed in the filling layer, comparing the cable that blocks water with ordinary cable and blocking water effectually, tensile strength is strong, and this kind of cable has prolonged the life of cable, has reduced use cost.
Description
Technical field
The utility model relates to field of cables, relates to a kind of reinforced tension water repellent electric cable more specifically
.
Background technology
The application of cable very wide, common is mainly used in electric power system, the information transmission system etc., and the cable of power information comprises local cable, camera cable, light cable etc.
The most structure function of existing cable is single, and some cable has certain waterproof action, but in cable laying and after laying, cable bad happens occasionally, and cable joint process is bad etc. in addition, all can make to carry out in cable into water or aqueous vapor.Therefore in some cases .. waterproof requirement is proposed to cable.
In China, infrastructure construction constantly drops into, and the demand of power cable increases day by day.There is different performance requirements in different areas to power cable, as at harbour, the area such as harbour, reservoir, tunnel, because humidity is comparatively large, higher requirement is proposed to the water resistance of power cable or at some because of unexpected place of causing high temperature, common cable easily damages.
Utility model content
The utility model overcomes above-mentioned technical deficiency, provides a kind of reinforced tension water repellent electric cable.
The utility model to achieve these goals concrete by the following technical solutions:
A kind of reinforced tension water repellent electric cable, it is characterized in that, comprise four fan-shaped uniform cores, core comprises conductor and is wrapped in the inner insulating layer outside conductor, core is disposed with outward, water blocking layer, inner restrictive coating, armour, external sheath layer, be provided with packed layer between water blocking layer and inner restrictive coating, in packed layer, be provided with four circumferentially equally distributed reinforcement cable core and four annex cores.
Further, water blocking layer comprises drying from inside to outside and fills oxidant layer, expansion waterproofing rope layer, radial moisture-proof layer, and described expansion blocks water the basic unit that line comprises woven dacron and the particulate expandable be bonded in basic unit, and the material of particulate expandable is cellulose.
Further, described armour employing thickness is the wrapped formation of stainless steel belt spiral of 0.2 ~ 0.25mm.
Further, described reinforcement cable core is that 0.15 ~ 0.2mm zinc-coated wire twists again and forms by diameter.
Further, annex core comprises attached conductor and is wrapped in the attached inner insulating layer outside attached conductor.
The beneficial effects of the utility model are as follows:
Oxidant layer, expansion waterproofing rope layer, radial moisture-proof layer are filled in the drying that water blocking layer of the present utility model comprises from inside to outside, the described expansion line that blocks water comprises the basic unit of woven dacron and is bonded in particulate expandable in basic unit, the material of particulate expandable is cellulose, and block-water effect is good; Be provided with reinforcement cable core in packed layer, strong cable core is that 0.15 ~ 0.2mm zinc-coated wire twists again and forms by diameter, increases the tensile property of cable.
