Abstract
A novel cable accessory is provided, which relates to a power cable accessory, in particular to a power cable accessory for connecting the middle section and end section of cable. The utility model is intended to overcome the problems of instable performance in existing thermal shrinkage cable accessory and the higher price of existing cold shrinkage cable accessory. The technical proposal of the utility model is: replace a stress tube in the thermal shrinkage cable accessory into a stress cone insulation layer made of elastic material and a cold shrinkage stress cone composed of a semiconduction stress cone built in the insulation layer, so the utility model can be provided with the advantages of low cost in thermal shrinkage cable accessory and the stable performance in the cold shrinkage cable accessory.
Description
Technical field
The utility model relates to a kind of electric cable fitting, a kind of middle novel cable annex that is connected with terminal of cable that is used for.
Background technology
At present, be used for annex that power cable connects and comprise two kinds of pyrocondensation electric cable accessories and cold shrinking power cable adjuncts, no matter pyrocondensation electric cable accessories or cold shrinking power cable adjunct, its critical component is the electric field stress control unit, be stress tube or stress cone, general pyrocondensation electric cable accessories is a stress tube, and cold shrinking power cable adjunct is a stress cone.The stress cone of cold shrinking power cable adjunct disperses electric field by shape, its material is the semiconductor elastomeric material, stable and reliable for performance, and produce easily, but price is very high, and the stress tube of pyrocondensation electric cable accessories is to adopt a kind of special half heat conduction draw material to make, its material is a kind of polar macromolecule material, and its advantage is that cost is low, and shortcoming is a poor radiation, higher to manufacturing technique requirent, performance is stable inadequately.
The utility model content
In order to overcome pyrocondensation electric cable accessories poor radiation now, higher to manufacturing technique requirent, the shortcoming that performance is stable inadequately, the utility model provides a kind of novel cable annex, it is the semiconductor stresses awl that in the pyrocondensation electric cable accessories, the stress tube of pyrocondensation is replaced with cold-shrink type, thereby make the novel cable annex both have the low advantage of pyrocondensation electric cable accessories cost, have the advantage of cold shrinking power cable adjunct stable performance simultaneously again.
The technical scheme that its technical problem that solves the utility model adopts is: the electric field stress control unit of novel cable annex is replaced with the semiconductor stresses awl that stress cone insulating barrier of being made by the elastic insulating material of cold-shrink type and the semiconductor stresses that is built in the insulating barrier the inside are bored the cold-shrink type that constitutes by the thermal shrinkage type stress tube, utilize the stability of semiconductor stresses awl to guarantee stablizing of its performance.
The beneficial effects of the utility model are: because the semiconductor stresses awl is set in the pyrocondensation electric cable accessories, utilize the high stable characteristics of stress cone, overcome the inadequate natural endowment of stress tube material, the novel cable annex that the utility model is provided has the low advantage of cost, can guarantee stable performance again simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of an embodiment of prior art.
Fig. 2 is the structural representation of an embodiment of the utility model.
Embodiment
Among the figure, 1. stress dispersion agent, 2. stress tube, 3. insulated tube is 4. filled glue, 5. fluid sealant, 6. ground wire, 7. cable main, 8. stress cone insulating barrier, 9. semiconductive stress cone.
As can be seen, the pyrocondensation electric cable accessories of prior art is an example with the single-core cable terminal in Fig. 1, and its structure comprises: stress dispersion agent (1), stress tube (2), insulated tube (3), filling glue (4), fluid sealant (5), ground wire (6).
In embodiment of the present utility model shown in Figure 2 as can be seen, with the single-core cable terminal is example, and its structure of pyrocondensation electric cable accessories after the improvement comprises successively: insulated tube (3), filling glue (4), fluid sealant (5), ground wire (6) stress cone insulating barrier (8), semiconductive stress cone (9); In the present embodiment, the semiconductor stresses awl of cold-shrink type is to be made of elastic insulating material stress cone insulating barrier of making and the semiconductive stress cone that is built in the insulating barrier the inside, earlier the semiconductor stresses of cold-shrink type is bored predilation, in the chamber stay pipe is set within it then, when removing stay pipe, the stress cone inner chamber shrinks, the object that is socketed in the inside is tightened the ground cover to be caught, it has been technique known that the semiconductor stresses awl of cold-shrink type adopts the cold-shrink technology that stay pipe is set, and needn't describe in detail at this; When the novel cable annex that uses present embodiment to provide, at first go up and peel off outer jacket and sheath by the certain size standard in cable main (7), weld ground wire (6) and peel remaining copper shield and outer semiconductive layer and the insulating barrier of fining away again off and peel interior semiconductive layer off, the metal core is exposed; Be the stress cone that stress cone insulating barrier (8) and semiconductive stress cone (9) are formed then with the shrinkage electric field stress control unit that is lined with supporter in the cavity, be enclosed within Fig. 2 assigned address, extract supporter it is fixed, hold filling glue (4) fluid sealant (5) and fixed insulation pipe (3) again and finish construction.
Claims (1)
1. novel cable annex, comprise and it is characterized in that electric field stress control unit that is arranged on cable external insulation layer incision position and the pyrocondensation insulated tube that is socketed in its outside: the electric field stress control unit is being made of elastic insulating material stress cone insulating barrier of making and the semiconductive stress cone that is built in the insulating barrier the inside of cold-shrink type.
