Description
The present invention is based on Chinese patent number submitted by applicant in 12/22/2020
2020115254307A waterproof drawing head for composite smooth aluminum sheath cable and its production method "
At least some of the contents of the filed divisional application, original specification are incorporated herein by reference.
Technical Field
The invention relates to the technical field of cables, in particular to a cable traction head.
Background
In recent years, the high-voltage cable with the corrugated aluminum sleeve, which runs in an electric network system, has the electric corrosion phenomenon for a plurality of times, and when severe, the cable breakdown accident can occur, so that the serious hidden trouble is generated for the safe running of the electric network. The applicant has developed a new type of composite smooth aluminium jacketed high voltage cable product. In the laying construction of the composite smooth aluminum sleeve cable, how to effectively prevent water from entering in the direct-buried or through-pipe laying cable is an important problem to be solved by cable manufacturers.
In the past, the high-voltage cable with the corrugated aluminum sleeve adopts modes such as sealing heads, welding and the like, but in the actual laying process, the welding seam of the cable pulling head is often pulled and broken, and even the cable pulling head is pulled and separated due to irregular bending of a cable pipeline. When water exists in the pipeline, a large amount of water can enter the cable or the conductor, so that the product quality of the cable is seriously influenced, and serious hidden danger is caused to the safe operation of the cable.
The conventional waterproof traction head is specially designed for conveniently installing and laying corrugated aluminum sleeve cables, has a simple structure, can be mastered by a manufacturing process, and can completely meet the requirements on the cable laying environment of various occasions.
The design of the waterproof traction head of the corrugated aluminum sleeve cable mainly adopts secondary sealing and the expansion waterproof function of an O-shaped rubber ring, and the installation technology of the waterproof traction head is patented. Because the secondary seal is designed, when the cable is subjected to high-strength tensile force, even if the welding seam of the aluminum outer protective tube and the aluminum corrugated tube is broken by pultrusion in the laying construction, the possibility that water enters the cable from the aluminum corrugated tube is still sealed by the inner seal layer. The sealing mode of the waterproof O-shaped rubber ring is adopted at the cable core, so that even if a large amount of water exists outside the traction sleeve, the water cannot leak in from the conductor core, and the waterproof effect is achieved.
However, for the high-voltage cable with the smooth aluminum sleeve structure, the aluminum sleeve is in integral close contact with the surface of the buffer layer of the cable insulating wire core, and the phenomena of cold joint, scorching and unstable welding can occur when the cable end surface traction head is welded. If the cable passes through the pipe with a large length in the place with a severe construction condition or in the south area with a high groundwater level, the traction head manufactured by the process is easily pulled out, and the water inlet of the cable end is easily caused. Once the cable is water in, it is very cumbersome to handle.

4) Then the lining gland 8 is sleeved into the cable conductor core 13 and pushed to the bottom, and the convex ring is lined in the smooth aluminum sheath tube 4.
5) And then performing primary welding, namely firmly welding the lining gland 8 with the inner opening of the opened smooth aluminum sheath tube 4, wherein the welding method adopts an aluminum welding rod to directly weld.
6) After the first welding, the material is cooled for 5-10 minutes.
7) The cable conductor core 13 is fitted into the pulling sleeve 12, and must be fitted to the bottom of the pulling sleeve when the core is fitted.
8) After the sleeve is sleeved, the middle section of the traction sleeve 12 is crimped by two to three times by using hydraulic pliers, so that the firm and reliable crimping is ensured.
9) After the crimping is completed, the waterproof sealing ring 9 and the flat gasket 10 are sequentially installed, and the waterproof sealing ring 9 is tightly pressed on the inner gasket gland 8 through gradual screwing of the nut 11.
10 The welded aluminum outer sheath 14 and the aluminum traction head body 16 are threaded onto the traction sleeve 12 and tightened.
11 The second welding is carried out, and the welding method adopts an aluminum welding rod to directly weld, namely, the aluminum outer protective tube 14 and the smooth aluminum protective tube 4 are firmly welded;
12 After cooling for 5-10 min, packaging the first layer of heat-shrinkable sleeve, wherein the first layer of heat-shrinkable sleeve is sealed on the secondary welding points, and the periphery of the first layer of heat-shrinkable sleeve is uniformly sealed;
13 And then packaging the second layer of heat-shrinkable sleeve, wherein the second layer of heat-shrinkable sleeve is sealed outside the first layer of heat-shrinkable sleeve. At this time, the sealing work of the waterproof traction head of the smooth aluminum sleeve cable is completed, and then the lifting hook pull ring 17 is screwed up in the spiral direction.
Because a gap is reserved between the corrugated aluminum sleeve and the cable insulation buffer layer, the aluminum sleeve can penetrate when being welded with the traction head, and the welding seam can be ensured to be firm and reliable. However, the smooth aluminum sleeve and the cable insulation buffer layer are compact in structure and basically have no gap, the aluminum sleeve cannot penetrate when being welded with the traction head, the phenomena of cold joint, scorching and infirm welding can occur, and the buffer layer and the insulation layer can be scalded. Therefore, the smooth aluminum sheath expanding device 100 shown in fig. 2 is adopted in this embodiment, the smooth aluminum sheath tube 4 at the end of the cable is expanded into a horn shape, so that a certain horn-shaped gap exists between the smooth aluminum sheath tube and the cable insulation buffer layer, when the smooth aluminum sheath tube and the aluminum outer sheath tube are welded, a certain gap is formed between the smooth aluminum sheath tube and the aluminum outer sheath tube, welding materials can permeate, and meanwhile, a larger welding area exists between the circular ring section of the smooth aluminum sheath tube and the inner wall of the rear port of the aluminum outer sheath tube, so that the welding seam can be ensured to be firm and reliable.
The lining gland is welded with the inner wall of the smooth aluminum sheath pipe circular ring section, so that the welded seam is firmer, and because the gap between the diameter-expanded part of the smooth aluminum sheath pipe and the cable buffer layer is increased, scorching and cold joint cannot be generated, so that welding penetration and welding seam are firmer.
The aluminum outer protective tube and the smooth aluminum protective tube are welded, the welding seam width can cover the circular ring section of the smooth aluminum protective tube, and meanwhile, the welding current is 10-20% higher than that of the traditional welding current, and the welding width is wider than that of the traditional welding, so that the welding seam is firmer.
After the secondary sealing is adopted, the possibility that water enters the cable from the smooth aluminum sheath pipe is sealed because a layer of sealing is still formed between the convex ring of the lining gland and the smooth aluminum sheath pipe even if the welding seam of the aluminum outer sheath pipe of the traction head and the smooth aluminum sheath pipe is broken by pultrusion in laying construction when the cable is subjected to high-strength tensile force. The sealing mode of the waterproof O-shaped rubber ring is adopted at the cable core, so that even if a large amount of water exists outside the traction sleeve, the water cannot leak in from the conductor core, and the waterproof effect is achieved. The labor and material resources in the aspect of a large number of after-sales services are saved, the working efficiency of laying construction is improved, and the cable quality is better ensured.
