Abstract
The utility model discloses a kind of watertight conductor, comprise the first conductor layer, outside the first conductor layer, extrude the first semi-conductive rubber layer; The second conductor layer adopting concentric manner with the first conductor layer is set outward at the first semi-conductive rubber layer, outside the second conductor layer, extrudes the second semi-conductive rubber layer; The 3rd conductor layer adopting concentric manner with the first conductor layer is set outward at the second semi-conductive rubber layer, outside the 3rd conductor layer, extrudes the 3rd semi-conductive rubber layer.Because semi-conductive rubber has conductivity, this material is added in the ampacity not affecting conductor in the middle of conductor layer, solves the performance of glue formula instability, make cable have very strong watertightness simultaneously.
Description
Technical field
The utility model relates to joins field of cable technology, particularly relates to a kind of watertight conductor.
Background technology
Watertight conductor is used for watertightness and requires, in high cable, in order to reach requirement, to need multiple working procedure, is coated with one deck glue, is coated with one deck glue during synnema, be coated with one deck glue during stranded conductor at every one deck after conductor wire drawing.The glue adopted is the glue that under normality, stickiness is very strong.
Prior art Problems existing and shortcoming:
(1) domestic at present glue formula is still immature, and want conductor and insulation adhesion after extruded insulation, but the conductor being coated with glue is extruding the environment through HTHP in process, and glue can lose primary characteristic, not with insulation adhesion.Insulation and conductor adhesion just lose good watertightness, and test shows, by the long sample of 1.5m, to soak in water, and add hydraulic pressure 6.75MPa, 6 hours pressing times, have water droplet to go out for one.
(2) scribble the conductor of glue in process of production because its viscosity does not disappear, be inconvenient to operate on the one hand, being easily stained with the impurity such as dust on the other hand, easily there are quality problems such as puncturing in cable finished product.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of performance solving glue formula instability, makes cable have the conductor of very strong watertightness simultaneously.
A kind of watertight conductor described in the utility model, comprises the first conductor layer, extrudes the first semi-conductive rubber layer outside the first conductor layer; The second conductor layer adopting concentric manner with the first conductor layer is set outward at the first semi-conductive rubber layer, outside the second conductor layer, extrudes the second semi-conductive rubber layer; The 3rd conductor layer adopting concentric manner with the first conductor layer is set outward at the second semi-conductive rubber layer, outside the 3rd conductor layer, extrudes the 3rd semi-conductive rubber layer.
Further improvement, the first described conductor layer is made up of single conductor.
Further improvement, the second described conductor layer is made up of six conductors.
Further improvement, the 3rd described conductor layer is made up of 12 conductors.
Compared with prior art, the utility model beneficial effect is: that conductor structure adopts is " 1+6+12 ", by being extruded with semi-conductive rubber layer outside every one deck conductor.Semi-conductive layer embedded conductor every layer of centre, semiconductive is extruded on conductor well can stick in conductive surface and conductor recess, semi-conductive layer in the middle of conductor has very strong radial frictional force and watertightness is fabulous, test shows the sample that 1.5m is long, soak in water, and add hydraulic pressure 6.75MPa, 6 hours pressing times for one, inside between conductor is not subjected to displacement, and sample does not have water droplet to go out.Because semi-conductive rubber has conductivity, this material is added in the ampacity not affecting conductor in the middle of conductor layer, solves the performance of glue formula instability, make cable have very strong watertightness simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of watertight conductor as shown in Figure 1, is characterized in that: comprise the first conductor layer 1, extrudes the first semi-conductive rubber layer 2 outside the first conductor layer 1; Adopt outside the second conductor layer 3, second conductor layer 3 of concentric manner in the outer setting of the first semi-conductive rubber layer 2 and the first conductor layer 1 and extrude the second semi-conductive rubber layer 4; Adopt the 3rd conductor layer 5 of concentric manner at the outer setting of the second semi-conductive rubber layer 4 and the first conductor layer 1, outside the 3rd conductor layer 5, extrude the 3rd semi-conductive rubber layer 6.
Operation principle of the present utility model:
What conductor structure described in the utility model adopted is " 1+6+12+18+6(n-1) (n is the number of plies) ", by starting at ground floor conductor, every layer is extruded with semi-conductive rubber layer outward.Semi-conductive layer embedded conductor every layer of centre, semiconductive is extruded on conductor well can stick in conductive surface and conductor recess, semi-conductive layer in the middle of conductor has very strong radial frictional force and watertightness is fabulous, test shows the sample that 1.5m is long, soak in water, and add hydraulic pressure 6.75MPa, 6 hours pressing times for one, inside between conductor is not subjected to displacement, and sample does not have water droplet to go out; Because semi-conductive rubber has conductivity, this material is added in the ampacity not affecting conductor in the middle of conductor layer.
The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
