Abstract
The utility model relates to a device for producing a longitudinal water-blocking cable, which comprises a stranding cage barrel (1) of a wire-stranding machine. A roll of cotton yarn (2) are arranged on an inner ring of the stranding cage barrel (1) of the wire-stranding machine. The cotton yarn (2) is wound on a longitudinally wrapping water-blocking tape (3). The longitudinally wrapping water-blocking tape (3) is tightly attached to a conductor (4). According to the utility model, the water-blocking conductor can be ensured to be longitudinally wrapped by adopting the water-blocking tape without being missed to be wrapped.
Description
Technical field
The utility model relates to the cable technology field that vertically blocks water, and particularly relates to a kind of device of cable of vertically blocking water that is used to produce.
Background technology
The client often requires cable manufacturer to produce the cable with vertical water-resisting ability according to the natural conditions of cable laying both at home and abroad at present.And being exactly the conductor of requirement cable, the difficult point of the cable that vertically blocks water has vertical water-resisting ability.Water-blocking conductor has following several kinds of production methods at present: inner each interlayer of conductor applies water-proofing powder, inner each interlayer winding water blocking yarn of conductor, inner each interlayer vertical bag waterstop of conductor or several method and mixes use.
Conductor is inner when applying water-proofing powder, and water-proofing powder itself just is difficult for being attached on the conductor layer, adds the shake of conductor when producing and causes water-proofing powder to come off more easily, reduces water-resisting ability, and water-proofing powder is shed on the equipment damage equipment easily in addition; Conductor is inner when twining water blocking yarn, needs special wrapped equipment, and wrapped power set are provided, and water-resisting ability does not have that water blocking yarn applies comprehensively or the comprehensive covered effect of waterstop is good; When the bag waterstop was indulged in conductor inside, easy to use, block-water effect was good, but was exactly because indulging containing is prone to bottom pour ladle and reduces water-resisting ability, caused product defective.Therefore adopt vertical bag waterstop mode to produce water-blocking conductor, cause the waterstop bottom pour ladle just to become a technical barrier and how to solve because of indulging packet mode.
Summary of the invention
The utility model technical problem to be solved provides a kind of device of cable of vertically blocking water that is used to produce, and can guarantee that water-blocking conductor adopts the vertical bag of waterstop and bottom pour ladle not.
The utility model solves the technical scheme that its technical problem adopted: a kind of device of cable of vertically blocking water that is used to produce is provided, comprises the strand cage cylindrical shell of stranding machine, a volume cotton yarn is installed on the inner ring of the strand cage cylindrical shell of said stranding machine; Said cotton yarn is wrapped on the vertical bag waterstop; Said vertical bag waterstop is closely docile and obedient at conductor.
Said conductor structure is 91/3.06mm.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art has following advantage and good effect: adopt the utility model, under the situation that does not increase any auxiliary device; Can guarantee water-blocking conductor to adopt the vertical bag of waterstop and bottom pour ladle not; The just a little thin cotton yarns of convenient being suitable for, the cost of increase almost can be ignored.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The execution mode of the utility model relates to a kind of device of cable of vertically blocking water that is used to produce, and is as shown in Figure 1, comprises the strand cage cylindrical shell 1 of stranding machine, and a volume cotton yarn 2 is installed on the inner ring of the strand cage cylindrical shell 1 of said stranding machine; Said cotton yarn 2 is wrapped on the vertical bag waterstop 3; Said vertical bag waterstop 3 is closely docile and obedient at conductor 4.
Utilize said apparatus trial-production to produce 1020 meters of YJSY 12.7/22kV 1 * 630 power cables, conductor structure is 91/3.06mm, and twisted wire is arranged as 1+6+12+18+24+30, specifically joins mould, the waterstop size sees the following form:
In the production process, center, 6 layers, 12 layers, 18 layers, 24 layers are indulged the waterstop that wraps and the bottom pour ladle phenomenon all do not occurred, produce after the conductor; Head and the tail are respectively got 10 meters; Layering strip off conductor does not successively all have the bottom pour ladle phenomenon from outside to inside, has reached Expected Results.
After each operation of road, through the whole vertically water blocking test of internal inspection cable, testing result is qualified after accomplishing.This batch cable is delivered to the Shanghai Electrical Cable Research Institute check, and testing result is also qualified.
Claims (2)
1. one kind is used to produce the device of cable of vertically blocking water, and comprises the strand cage cylindrical shell (1) of stranding machine, it is characterized in that, a volume cotton yarn (2) is installed on the inner ring of the strand cage cylindrical shell (1) of said stranding machine; Said cotton yarn (2) is wrapped on the vertical bag waterstop (3); Said vertical bag waterstop (3) is closely docile and obedient in conductor (4).
2. according to claim 1ly be used to produce the device of cable of vertically blocking water, it is characterized in that said conductor (4) structure is 91/3.06mm.
