Abstract
The utility model relates to a composite insulating tape, which is an interlayer cavity structure with a plastic tape. The cavity is filled with sponges or loose fabrics with insulating glue liquid and the inner side of the interlayer plastic tape is provided with a plurality of extruding slits for the glue liquid. To prevent the glue liquid concentrating backward in a winding process, the interlayer cavity is divided into a plurality of independent cavities along the longitudinal direction of the tape. The utility model can enable a conducting wire and the gap of the plastic tape to be filled with insulating glues, and therefore, water and wet air are unable to enter a wire heart to have a good sealing effect, save the traditional glue-pouring process and time and accelerate the construction speed.
Description
The utility model relates to the insulating tape that the cable or wire joint is used.
In the high-voltage cable joint process, after finishing, wiring must exposed blank area be wound up with insulating tape, soak insulating cement then.The purpose of invading glue is a reinforced insulation intensity, improves moisture resistance and fail safe.Because glue oozes from outside to inside along the insulating tape gap, the infiltration difficulty, required time is very long, influences construction schedule.Before the insulating cement water cure, adhesive tape bounces back naturally to become flexible and can destroy adhesive layer.During practical operation,, usually take place not soak into or hole problem how, make moisture still have opportunity, enter the electric wire inner core and produce discharge and blow cable because the impregnation time is not enough or the technology grasp is bad.Though the black insulating tape of low pressure may blow because of discharge after wearing out equally without encapsulating.The economic loss that causes thus is very huge.
The purpose of this utility model is to overcome above-mentioned shortcoming of the prior art, and provide a kind of can automatic coating in winding process glue to the insulating tape of faying face, save gum dipping process, save time, thereby improve work efficiency greatly, and can improve the quality of glue envelope.
Solution of the present utility model is: the ambroin band is made the interlayer cavity configuration, fill the soft porosity that contains the glue that insulate in the chamber; The interlayer medial surface has many glues and extrudes seam.Here said soft porosity can be sponge or loose fabric etc.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the cross-sectional view of composite bed insulating tape.
Fig. 2 is an insulating tape inner surface diagrammatic sketch.
Fig. 3 is the end view of Fig. 2.
Among Fig. 1, constitute the interlayer chamber 2 of sealing, fill the sponge 3 that contains glue in the chamber by ambroin band 1.Have many glue at the adhesive tape inner surface and extrude seam 5, as shown in Figure 2.
Concentrated too backward in winding process in order to prevent glue, can vertically the packing of interlayer chamber be become many independently cells 8 along insulating tape, hot sticky joint close 7 is the packing line between chamber among the figure.
Multiple one deck anti-aging ribbon 9 can be covered in above-mentioned insulating tape surface, to improve the useful life of insulating tape.
During use, the tension insulating tape twines, and contained glue flow to from extrude seam in the two-layer insulating tape gap in the sponge under the effect of extruding force, is full of institute and has living space, and have a part of surplus glue and extrude the outside.After insulating cement solidifies, just both sides cable insulation skin, lead and insulating tape are bonded to the closely knit integral body that does not have air to exist.
This composite insulating tape is compared with traditional gum dipping process, has following advantage:
1, be full of insulating cement in lead and the insulating tape slit, play the excellent sealing effect, water and humid air can't enter the line heart, have improved dielectric strength and humidity resistance.
2, when twining insulating tape, interlayer automatic filling insulating cement has saved traditional impregnation operation, saves time, and speed of application is accelerated greatly.
3, glue is oozed out by inside, and glued membrane is not fragile in the solidification process, and the quality of bonding is good.
Claims (4)
1, composite bed insulating tape comprises ambroin band (1), it is characterized in that said plastic tape (1) constitutes interlayer chamber (2), fills the soft porosity (3) that contains the glue that insulate in the chamber; Interlayer plastic tape medial surface has many glues and extrudes seam (5).
2, insulating tape as claimed in claim 1 is characterized in that said soft porosity (3) is sponge or loose fabric.
3, insulating tape as claimed in claim 1 or 2 is characterized in that said interlayer chamber (2) becomes many independently cells (8) along vertical packing of band, to prevent that glue is concentrated backward in the winding process.
4, insulating tape as claimed in claim 1 or 2 is characterized in that in the outer surface illiteracy of interlayer chamber plastic tape (1) anti-aging ribbon (9) being arranged again.
