Description

Technical Field

[0001] This invention relates to the field of cable technology, and more specifically, to a method for manufacturing a high-voltage cable and a high-voltage cable itself. Background Technology

[0002] High-voltage cables are often installed outdoors and exposed to the elements. In winter, the cable surface can become covered with snow and ice. When the weight of the ice exceeds the cable's load-bearing capacity, it can cause the cable to break and the circuit equipment to malfunction. Therefore, it is necessary to deal with the snow and ice accumulation on high-voltage cables.

[0003] Currently, ice on cables is mainly removed using de-icing machines or by manual climbing. Using de-icing machines requires a large number of devices, increasing maintenance costs. Manual removal poses safety hazards due to the high height of the cables. Summary of the Invention

[0004] To increase the efficiency of handling icing on the outer side of cables, the present invention adopts the following technical solution:

[0005] The purpose of this invention is to provide a solution for setting a hollow ventilation channel inside the cable. When the cable is in a low-temperature environment, air at a suitable temperature is injected into the ventilation channel to melt the ice layer on the cable surface, thereby increasing the efficiency of handling icing on the outside of the cable.

[0006] To achieve the above objectives, the present invention provides a method for manufacturing a high-voltage cable, comprising the following steps:

[0007] Step 1: Install multiple cables around the periphery of the airbag core;

[0008] Step 2: Encapsulate the outer sheath of multiple cable wires to obtain a standard length cable;

[0009] Step 3: Connect multiple standard length cables together one by one to obtain the high-voltage cable product.

[0010] The cable of this application has an air-filled core as its main body, and multiple cable wires are installed around the air-filled core. The multiple cable wires are covered with an outer sheath. Attached Figure Description

Detailed Implementation

[0022] To increase the efficiency of handling icing on the outer side of cables, this invention provides a method for manufacturing high-voltage cables, comprising the following steps:

[0023] Step 1: Install multiple cables 12 around the periphery of the airbag core 13;

[0024] Step 2: Encapsulate the outer sheath 11 on the outside of multiple cable wires 12 to obtain a standard length cable;

[0025] Step 3: Connect multiple standard length cables together one by one to obtain the high-voltage cable product.

[0026] The main body of the cable 1 in this application is an airbag core 13, and multiple cable wires 12 are installed around the airbag core 13. An outer sheath 11 is provided on the outside of the multiple cable wires 12.

[0027] The following describes specific embodiments of the present invention.

[0028] Reference Figure 2-5 The following are examples illustrating the ease of storage, splicing, preparation, and use of the high-voltage cable provided by this invention:

[0029] The airbag core 13 of this application has a recessed edge on its side that fits against the outer surface of the cable 12, and a rough surface 14 is provided on the recessed edge.

[0030] Because the rubber core 13 has a certain strength, it can maintain its shape and not deform. Furthermore, the tight fit between the rough surface 14 and the outer side of the cable 12 prevents the cable 12 from moving around on the side of the core 13, making the high-voltage cable easy to store and splice.

[0031] Reference Figure 2 and Figure 4-5 The following is an example illustrating an embodiment in the high-voltage cable manufacturing method provided by the present invention that increases the efficiency of handling icing on the outer side of the cable:

[0032] The airbag core 13 of this application is hollow inside. Both ends of the airbag core 13 are respectively provided with screw holes 15 and threaded flanges 16. The two airbag cores 13 are connected and communicated through the threaded engagement of the screw holes 15 and the threaded flanges 16.

[0033] When the cable is in a low-temperature environment, injecting air at a suitable temperature into the ventilation channel will melt the ice layer on the cable surface, thereby increasing the efficiency of dealing with icing on the outside of the cable.

[0034] Reference Figure 2 and Figure 6-7 The illustration shows an embodiment of the high-voltage cable manufacturing method provided by the present invention, in which multiple standard-length cables are connected together one by one:

[0035] The specific steps for connecting multiple standard-length cables together in this application are as follows:

[0036] The cable wires 12 on adjacent standard length cables are welded together, and the outer sheaths 11 on adjacent standard length cables are bonded together.

[0037] Furthermore, the end of the outer sheath 11 is processed with multiple C-shaped channels 17 by an auxiliary docking device. The C-shaped channels 17 on adjacent standard length cable sheaths 11 can be connected to each other. Connectors are provided in the C-shaped channels 17 to enhance the stability of connecting multiple standard length cables one by one.

[0038] Reference Figure 6-8 The illustration shows an embodiment of the method for manufacturing a high-voltage cable provided by the present invention, which involves aligning the outer sheath 11, cable wires 12, and air bladder core 13 within the cable 1:

[0039] The main body of the auxiliary docking equipment of this application is a processing base 21. A connecting plate 22 is installed on the lower side of the top of the processing base 21. An upper arc-shaped clamping plate 23 is fixedly installed on the connecting plate 22. A lower arc-shaped clamping plate 31 is movably installed on the lower side of the upper arc-shaped clamping plate 23. The lower arc-shaped clamping plate 31 and the upper arc-shaped clamping plate 23 can be interlocked to clamp the standard length cable.

[0040] Multiple hinge posts 33 are fixedly connected to the sides of the upper arc-shaped clamping plate 23 and the lower arc-shaped clamping plate 31. The hinge posts 33 on the upper arc-shaped clamping plate 23 and the lower arc-shaped clamping plate 31 are hinged together by hinge arms 32. A limit baffle 24 is fixedly installed at the end of the upper arc-shaped clamping plate 23.

[0041] A telescopic actuator 34 is rotatably mounted on the bottom of the connecting plate 22, and the movable end of the telescopic actuator 34 is rotatably connected to the hinge arm 32.

[0042] The upper arc-shaped clamping plate 23, the lower arc-shaped clamping plate 31, and the two sets of hinged columns 33 form a parallelogram mechanism. During the reciprocating extension and retraction process of the telescopic driver 34, the lower arc-shaped clamping plate 31 is driven to swing under the upper arc-shaped clamping plate 23. During this process, the cable 1 is placed on the lower arc-shaped clamping plate 31. When the lower arc-shaped clamping plate 31 swings rapidly towards the upper arc-shaped clamping plate 23, the outer sheath 11, cable wire 12, and airbag core 13 inside the cable 1 are aligned by the blocking effect of the limiting baffle 24, so that the two aligned sections of the cable 1 can be connected later.

[0043] Furthermore, the lower arc-shaped clamping plate 31 can be made shorter, so that when the upper arc-shaped clamping plate 23 and the lower arc-shaped clamping plate 31 abut against each other, there is a gap between the lower arc-shaped clamping plate 31 and the limiting baffle 24, so as to fully align the outer sheath 11, cable wire 12 and airbag core 13 inside the cable 1.

[0044] Reference Figure 2 , Figure 6-7 and Figure 9 The illustration shows an embodiment of the high-voltage cable manufacturing method provided by the present invention, in which a C-shaped channel 17 is formed at the end of the outer sheath 11, and multiple standard length cables are spliced ​​and connected through the C-shaped channel 17:

[0045] In this application, a plurality of sleeves 41 are fixedly connected and connected to the limiting baffle 24, and a grooving cutter body 42 is slidably installed on the sleeve 41. The grooving cutter body 42 is an arc-shaped structure that matches the C-shaped channel 17.

[0046] The end of the grooving cutter body 42 is equipped with a control handle. By holding the control handle, the grooving cutter body 42 is driven to slide inside the sleeve 41 to perform grooving on the outer skin 11, forming a C-shaped channel 17 at the end of the outer skin 11.

[0047] During the splicing and connection of multiple standard length cables, the C-shaped channels 17 on the outer sheaths 11 of adjacent cables 1 are connected by wires or C-shaped steel parts to firmly connect the outer sheaths 11 of the cables 1.
