Embodiment

[0028] Such as figure 1 and figure 2 A cable with high compressive resistance is shown, including a cable core body 3, a functional layer 1, an armor layer 7 and an outer sheath 6 arranged sequentially from the inside to the outside, as shown in Figure 5 As shown, the cable core body 3 includes a wire core 10, an inner protective layer 9 coated on the surface side of the cable core body 3, and a filler material 21 filled around the wire core 10; Flame retardant, waterproof and other advantages of at least one material, so that the cable has the corresponding performance; the armor layer 7 can adopt non-magnetic stainless steel belt interlocking armor structure, the metal armor layer set in this way has excellent Mechanical, compressive, antimagnetic, fireproof, easy to bend and other performances, and also has anti-theft, anti-insect bites, etc., which can enhance the related performance of the cable; the outer sheath 6 can be made of low-smoke halogen-free rubber, and its ...

Embodiment 2

[0033] The difference between this embodiment and embodiment 1 is:

[0034] In this example, if figure 1 and Figure 4 As shown, the inside of the second compression layer 5 is provided with a third compression layer 2 and a fourth compression layer 11 located inside the third compression layer 2, and the outside of the third compression layer 2 is provided with The first elastic layer 8, the inner side of the fourth anti-pressure layer 11 is provided with the second elastic layer 4, the first elastic layer 8 and the second elastic layer 4 can be made of rubber, the fourth anti-pressure layer 11 includes inner anti-pressure blocks 18 fixedly arranged at equal intervals along the outer peripheral side of the second elastic layer 4, and the third anti-pressure layer 2 includes outer anti-pressure blocks 17 fixedly arranged at equal intervals along the inner peripheral side of the first elastic layer 8, Both the outer anti-compression block 17 and the inner anti-compression blo...

Embodiment 3

[0038] The difference between this embodiment and embodiment 2 is:

[0039] In this example, if Figure 5 and Figure 6 As shown, the cable core body 3 is provided with a protective bracket 20 located inside the inner protective layer 9. The protective bracket 20 can be made of copper material. The small round bracket 22 on the outside and the large round bracket 23 attached to the inside of the inner protective layer 9, the side of the small round bracket 22 facing away from the center of the cable section is fixed together with the large round bracket 23, and every adjacent two small round brackets The round brackets 22 all interfere with each other. Small circle support 22 and large circle support 23 are all circular, have anti-compression effect, and by each small circle support 22 contradict each other and small circle support 22 and big circle support 23 are fixedly connected, make between each small circle support 22 and Both the small round bracket 22 and the big ro...

Abstract

The invention discloses a cable with high compression resistance function, which belongs to the technical field of power cables, and comprises a cable core main body, a functional layer, an armor layer and an outer sheath arranged sequentially from the inside to the outside, and the cable core main body includes a wire core , inner protective layer and filling materials; between the inner protective layer and the functional layer, the first anti-compression layer, the second anti-compression layer, the third anti-compression layer and the fourth anti-compression layer are arranged in sequence from the outside to the inside, the first anti-compression layer The lamination layer includes a plurality of first compression units distributed in a ring, and the first compression unit includes a large arc plate and a small arc plate opposite to each other in the radial direction of the cable, and is connected between the large arc plate and the small arc plate. The two ends of the small arc-shaped plate are in contact with the two sides of the corresponding large arc-shaped plate, and the corresponding end sides of every two adjacent large arc-shaped plates are in conflict. The present invention has good compressive capacity and can realize comprehensive compressive resistance to cables, thereby helping to prevent cable short-circuit faults caused by partial compression of cables.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a cable with high compression resistance. Background technique [0002] Cables are quite common in today's society. With the popularization of electricity, cables can be seen everywhere. Cables can be divided into many types according to their uses, some are used for power transmission, some are used for data transmission, and so on. In the case of local pressure, it will cause a short circuit fault in the cable, so it is necessary to design a cable with a high pressure resistance function. Contents of the invention [0003] 1. Technical problems to be solved [0004] The technical problem to be solved by the present invention is to provide a cable with high compression resistance, which has good compression resistance and can realize the overall compression resistance of the cable, thereby helping to prevent cable short circuit caused by partial compression of the cable...
