Abstract
The utility model discloses a medium-high-voltage crosslinked cable end socket cap. The medium-high-voltage crosslinked cable end socket cap comprises a cap body. An air nozzle is disposed on the top of the cap body and is fixedly connected with the cap body. A flexional valve core is disposed in the air nozzle and is bent horizontally to present an angle from 15 to 60 degree. The cable end socket cap equipped with the air nozzle is applied to the medium-high-voltage crosslinked cable end socket cap. The reconstructed cable end socket cap not only prevents external moisture from entering the cable, but also enables the air in the cable to be expelled out from the air nozzle at any time. Therefore, air pressures in the cable and outside the cable are balanced and thus a sheath is guaranteed not to be expanded.
Description
Technical field
The utility model belongs to electric wire manufacturing technology field, is specifically related to a kind of cable end socket cap that can effectively prevent middle and high pressure crosslinked cable jacket expansion.
Background technology
3.6/6KV and above crosslinked cable is in cable production; having inspected the back causes cable quality and has a strong impact on for anti-sealing enters cable; the general tack pyrocondensation end socket cap that adopts seals cable socket; owing to contain the DCP crosslinking agent in the employed insulating material when cable is produced; its consumption changes and disperses uneven problem to avoid; therefore regular meeting causes and decomposes insufficient at the crosslinked step D CP of cable the time; to finished cable processing; still decompose after having inspected the sealing termination in continuation; produce a large amount of gases; cable cover(ing) is produced pressure; make jacket expansion, cable quality is impacted.
In the prior art, for solving the influence that cable cover(ing) expands cable quality is caused, two kinds of methods are arranged at present: the one, employing is put into drying room to insulated wire cores and is heated after crosslinked operation is finished, residual DCP is decomposed, thereby the gas that is produced by residual DCP decomposition behind following process process and sealing termination significantly reduces, and reaches the not dilatable purpose of cable cover(ing).There is following problem in the method: need take the bigger place resource of workshop; Drop into special equipment, increase the cost expenditure; Consumes energy.The 2nd, finish the relief insulated wire cores in crosslinked operation and suspend processing, placed for 1～2 week, residual DCP is further decomposed, thereby reduce the gas that sealing back, termination produces.It is long that the method semi-finished product are put the time, bigger to the influence at delivery date, the situation of customer requirements often occurs can't satisfying delivery date.
The utility model content
At the deficiencies in the prior art, the utility model provide a kind of simple in structure, easy to operate, cost is low, can effectively prevent the cable end socket cap of middle and high pressure crosslinked cable jacket expansion.
The technical solution of the utility model: a kind of middle and high pressure crosslinked cable end socket cap, comprise the cap body, described cap body top is provided with valve, and the cap body is fixedlyed connected with valve; Flexible valve inside is set in the described valve.
Described valve inside horizontal curvature is 15～60 °.
As preferably, described valve inside horizontal curvature is 30 °.
The gap of described valve inside and valve inwall is 0.1～0.3mm.
As preferably, the gap of described valve inside and valve inwall is 0.2mm.
Technique effect of the present utility model:
(1), the utility model cable end socket cap that will have a valve is applied on the middle and high pressure crosslinked cable, can prevent that through improved cable end socket cap extraneous moisture from entering cable, gas in the cable is discharged from valve at any time, reach the cable inside and outside air pressure balance, thereby guarantee that sheath does not expand.
(2), the gap of control valve inside and valve inwall, and adjust the angle of giving vent to anger of valve inside, gas is discharged easily, the while can stop moisture to enter cable again preferably.
(3), the utility model is easy and simple to handle, with low cost, both solved the problem that 3.6/6KV and above middle and high pressure crosslinked cable oversheath expand, and overcome problems such as the production cycle is long in the prior art, energy resource consumption is big again, have a good application prospect.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the accompanying drawing of required use is done to introduce simply in will describing embodiment below, apparently, accompanying drawing in describing below only is one of them embodiment of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
