Abstract
The invention discloses a wall bushing for the installation of a cable. The wall bushing comprises an insulator, an umbrella skirt, a sheath and an installation plate. The insulator is hollow. The umbrella skirt is equidistantly distributed at the two ends of the outer side of the insulator. The sheath is arranged at the middle of the insulator. The installation plate is welded on the outer side of the sheath. A conductive tube is arranged inside the insulator. The conductive tube is internally filled with a silica gel desiccant layer. A PVC layer and a wrapping tape layer are arranged between the insulator and the conductive tube. The two ends of the conductive tube are respectively provided with a hoop. Each hoop is correspondingly welded with two wiring boards and the wiring boards are provided with threaded holes. According to the technical scheme of the invention, the wall bushing for the installation of the cable is good in insulation effect, and easy to assemble and disassemble. Simultaneously, the wall bushing has the drying function.
Description
Technical field
The present invention relates to a kind of cable installation wall bushing.
Background technology
Wall bushing is called and does wall pipe, water string, wall pre-embedded pipe, and water string is divided into rigid waterproof sleeve and soft
Property water string.It is used for conductive crying on electric power and exchanges wall bushing, can be divided into dry-type capacitance type from material and exchange set through walls
Pipe exchanges wall bushing with porcelain insulating, is referred to as respectively silicone rubber sleeve and porcelain bushing shell.Refer to that pipeline wears concrete floor, common brick
During wall, the reserving hole typically all on concrete floor, common brick wall can after dug wall eye.At floor, before peace pipeline,
Fall logical line, sleeve pipe is installed.On brick wall, setting-out, cultivation set support, find slope.By first winding, oversheath, silicon rubber umbrella skirt, two ends
Grading shield, flange and conductor wire clamp etc. are constituted.Oil-free, without gas, without porcelain, small volume, lightweight, maintenance workload be little, fire prevention is anti-
It is quick-fried and set up high-precision penetration type current transformer.Due to along face voltage's distribiuting it is uniform and using silastic material as outer
Insulation, can further improve pollution flashover voltage.Epoxy resin APG operation pressure gel forming structures, it is suitable for rated voltage
In 12KV, 35KV and following complete set of equipments, excessively use as being dielectrically separated from and coupling.
At present existing wall bushing insulation effect is general, it is not easy to assembly and disassembly, while not having functions/drying.
The content of the invention
It is good that the technical problem to be solved in the present invention is to provide a kind of pipe insulation effect, easy assembly and disassembly, while having
The cable installation wall bushing of functions/drying.
To solve the above problems, the present invention is adopted the following technical scheme that：A kind of cable installation wall bushing, including insulation
Son, full skirt, sheath and installing plate, the insulator is in hollow setting, and the full skirt is in be equally distributed on two ends on the outside of insulator,
The sheath is arranged on insulator middle part, and the installing plate is welded on sheath outside, contact tube, institute are provided with the insulator
State in contact tube filled with silica dehydrator oxidant layer, polyvinyl chloride layer and twining package tape are provided between the insulator and contact tube
Layer, the contact tube two ends are separately installed with anchor ear, and each described anchor ear correspondence is welded with two terminal plates, on the terminal plate
It is provided with screwed hole.
Preferably, the installing plate is vertical setting with sheath, insulator can be passed through after drilling on body of wall, and be pacified
Dress plate is arranged on body of wall by screw or other securing members.
Preferably, the insulator is ceramic insulator, keep insulation effect good.
Preferably, the contact tube, wrapped belt, polyvinyl chloride layer and insulator are arranged from the inside to the outside successively, it is wrapped
Belt and polyvinyl chloride layer can lift insulation effect.
Preferably, the anchor ear two ends are provided with fixing screws, fixing screws allow anchor ear to be fixed on contact tube
Outside.
Beneficial effects of the present invention are：Polyvinyl chloride layer and twining package tape are provided between the insulator and contact tube of setting
Layer so that insulation effect is good；The anchor ear of setting causes terminal plate easily in contact tube over-assemble and dismounting；The silica dehydrator of setting
Oxidant layer has functions/drying, can keep the drying inside contact tube.
Description of the drawings
Fig. 1 is a kind of structure chart of cable installation wall bushing of the invention.
Fig. 2 is a kind of insulator profile of cable installation wall bushing of the invention.
Specific embodiment
As depicted in figs. 1 and 2, a kind of cable installation wall bushing, including insulator 1, full skirt 2, sheath 3 and installing plate

The middle part of insulator 1, the installing plate 4 is welded on the outside of sheath 3, and in the insulator 1 contact tube 5, the contact tube 5 are provided with
It is interior filled with silica dehydrator oxidant layer 6, polyvinyl chloride layer 7 and wrapped belt 8, institute are provided between the insulator 1 and contact tube 5
State the two ends of contact tube 5 and be separately installed with anchor ear 9, each correspondence of the anchor ear 9 is welded with two terminal plates 10, the terminal plate 10
On be provided with screwed hole 11.
The installing plate 4 is vertical setting with sheath 3.
The insulator 1 is ceramic insulator.
The contact tube 5, wrapped belt 8, polyvinyl chloride layer 7 and insulator 1 are arranged from the inside to the outside successively.
The two ends of the anchor ear 9 are provided with fixing screws 12.
When in use, the conductor of cable is placed on the outside of terminal plate 10, passes through screw, conductor to be wound on screw on screwed hole 11
Outside is fixed.
Beneficial effects of the present invention are：Polyvinyl chloride layer and twining package tape are provided between the insulator and contact tube of setting
Layer so that insulation effect is good；The anchor ear of setting causes terminal plate easily in contact tube over-assemble and dismounting；The silica dehydrator of setting
Oxidant layer has functions/drying, can keep the drying inside contact tube.
The above, the only specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, all should be included within the scope of the present invention.
