Abstract
The utility model relates to a waterproof pulling device for a high-voltage crosslinked cable, which comprises a pulling head and a clamping bush, wherein the pulling head comprises a head end and a tail end; the head end and the tail end are communicated through a pulling tube; and the head end is connected with the clamping bush in a threaded connection mode. The utility model lowers the manufacturing difficulty and manufacturing cost of the pulling head, lowers the laying difficulty of the workers, and enhances the production efficiency; and in addition, the utility model has a favorable seal effect on the ends, and effectively prevents the phenomenon of water trees.
Description
Technical field
The utility model relates to the electric wire field of accessories, particularly relates to a kind of high-pressure cross-linking cable waterproof draw-gear.
Background technology
High-pressure cross-linking cable is when buried-pipe laying, if the termination is not protected, after water, gas got into, the cable long-play caused that easily insulating barrier water tree punctures, and final guiding discharge or cable are blown out, and the consequence of generation is hardly imaginable.In addition, the high-tension cable dead weight is very big, if do not adopt reasonable and firm mode of traction to draw, can cause workman's difficulty of construction big, and the cable unbalance stress, and cable is caused damage.The present high-tension cable draw-gear that adopts of each cables manufacturing factory reduces workman's big problem of worker's difficulty when laying though reached, and has all that effectively waterproof and drawing head manufacture difficulty are big, the problem that processing cost is high.
Summary of the invention
The utility model technical problem to be solved provides a kind of high-pressure cross-linking cable waterproof draw-gear, to solve high-tension cable cable socket water inlet and the big problem of workman's difficulty of construction when laying.
The utility model solves the technical scheme that its technical problem adopted: a kind of high-pressure cross-linking cable waterproof draw-gear is provided, comprises drawing head and clamping sleeve, said drawing head comprises head end and tail end; Said head end and tail end are communicated with through traction tube, and said head end links to each other through the mode that is threaded with said clamping sleeve.
The threaded connection place of said head end and said clamping sleeve is provided with sealing ring.
Said sealing ring is a rubber washer.
The somewhat larger in diameter of the tail end of said drawing head is in the diameter of the conductor of putting into.
Described drawing head is processed by the 45# steel.
Described clamping sleeve is made of aluminum.
Beneficial effect
Owing to adopted above-mentioned technical scheme; The utility model compared with prior art; Have following advantage and good effect: the utility model has not only reduced the manufacture difficulty and the manufacturing cost of drawing head, and has reduced workman's the difficulty of laying, and has improved production efficiency; And good sealing effectiveness has been played in the termination, effectively prevented the generation of water tree phenomenon.

Fig. 2 is the cutaway view of the clamping sleeve of the utility model;
Fig. 3 is the cutaway view 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 high-pressure cross-linking cable waterproof draw-gear, and is as shown in Figure 3, comprises drawing head 1 and clamping sleeve 2, and said drawing head 1 comprises head end 11 and tail end 12; Said head end 11 is communicated with through traction tube 13 with tail end 12, and said head end 11 links to each other through the mode that is threaded with said clamping sleeve 2.
The drawing head material is the 45# steel, because 45# steel good mechanical property, hardness is big, can bear big pulling force and pressure.As shown in Figure 1, the position that tail end 12 conductors of drawing head 1 get into is generally than about the big 0.5mm of conductor, and too little conductor is difficult to get into, and too big conductor can't closely contact with traction tube, can't bear big tractive effort, loose easily cover when laying.Conductor gets into after the traction tube, carries out crimping with hydraulic tongs, increasing the mechanical strength that traction tube is connected with conductor, thereby bears big pulling force, plays the purpose of traction.
The clamping sleeve material is an aluminium, and the purpose of selecting aluminium for use is in order to make it can be easy to weld with the aluminium cover.Its section is as shown in Figure 2, and the effect of clamping sleeve 2 is effectively cable socket to be carried out seal protection, to prevent the entering of water, gas.
As shown in Figure 3, conductor 4 is got into by the tail end 12 of drawing head 1, and passes traction tube 13 arrival head ends 11, and the head end 11 of drawing head 1 leans on screw thread closely to be connected with clamping sleeve 2.It should be noted that head end 11 positions that cooperate with clamping sleeve 2 at drawing head 1, be added with a sealing ring 3, like rubber washer.Though existing screw thread closely is connected between drawing head 1 and the clamping sleeve 2, adds rubber washer in this position, can better sealing effectiveness is played in the entering of anti-effectively sealing, gas.
With 64/110kV YJLW03630mm2 cable waterproof drawing head for example, 630mm
2The compact conductor external diameter is 30.0mm, and then the drawing head caliber is 30.5mm, and the crimping internal diameter is 30.0mm.This shows that the equal close fit of size that drawing head and clamping sleeve are all is to reach the purpose of traction and waterproof.
