Description

Technical Field

[0002] Cable is a general term for optical cables, electrical cables, etc. Cables have many uses, mainly used for controlling installation, connecting equipment, transmitting electricity, and other multiple functions. They are common and indispensable in daily life.

[0003] The Chinese patent with announcement number CN213815600U discloses a cold-resistant mineral cable, wherein a cold-resistant protective layer is fixedly installed on the outer side of the copper core of the cable, and the cable copper core and the cold-resistant protective layer are in close contact with each other, a shock-absorbing protective layer is fixedly installed on the outer side of the cold-resistant protective layer, and the cold-resistant protective layer and the shock-absorbing protective layer are in close contact with each other, and an anti-wear metal protective layer is fixedly installed on the outer side of the shock-absorbing protective layer, and the shock-absorbing protective layer and the anti-wear metal protective layer are in close contact with each other. This solves the problem that most existing mineral cables have only one protective layer on the outer side of the mineral layer, which is easy to wear and tear, and then it is easy to damage the mineral layer, resulting in poor fireproof effect, and at the same time, the waterproof performance is also poor and leakage is easy to occur, and the cable is very easy to freeze in winter.

[0004] Although the above-mentioned cold-resistant mineral cable protects the cable from being worn by the wear-resistant metal protective layer and increases the anti-tension force, the metal layer has poor flexibility and is prone to bending, making the laying of the cable inconvenient. Moreover, it is easy to deform after being squeezed and cannot be restored, which further affects the laying of the cable. Utility Model Content

[0005] In order to solve the problem that the cold-resistant mineral cable is inconvenient to lay after being deformed or bent, the present application provides a plateau saline-alkali land anti-corrosion cable, which adopts the following technical solution:

[0006] A plateau saline-alkali land anti-corrosion cable comprises a protective layer, a first insulating layer is arranged on the inner side of the protective layer, and a plurality of conductive cores are arranged on the inner side of the first insulating layer, the outer sides of the plurality of conductive cores are all wrapped with a second insulating layer, and the gap between the outer side of the conductive core and the first insulating layer is filled with glass fiber wool, a plurality of evenly arranged protective strips are fixed on the outer side of the protective layer, and steel wires are arranged on the inner side of the protective strips, and a protective pad is arranged between two adjacent protective strips.

[0007] Optionally, the protective layer and the protective strip are both made of fluorosilicone rubber, and slots are provided on both sides of the protective strip.

[0008] Optionally, two sides of the protective pad are respectively inserted into the slots on the protective strips on both sides, and a plurality of support plates are fixed to an inner side of the protective pad.

[0009] Optionally, a plurality of evenly arranged partition plates are fixed to the outer side of the first insulating layer, and the outer edges of the partition plates are pressed against the inner side walls of the protective layer.

[0010] Optionally, a buffer layer is provided between two adjacent partition plates, and the buffer layer is filled with polyurethane particles.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] In the utility model, multiple protective strips are arranged on the outside of the protective layer and steel wires are arranged inside the protective strips, which can prevent the cable from being directly in contact with external objects and being worn. The protective pads are further improved the wear resistance of the cable. While realizing the anti-wear protection of the cable, it also greatly improves the tensile resistance of the cable without affecting the flexibility of the cable, thereby not affecting the laying of the cable.
