Description

Technical Field

[0001] The present invention relates to the field of power transmission and distribution, and in particular to a low-voltage busbar and a cable for electric energy transmission. Background Art

[0002] Currently, low-voltage busbars and cables are commonly used for low-voltage power transmission. Low-voltage busbars, which often use copper busbars as conductors, suffer from poor heat dissipation, increased temperatures, low conductor utilization, high casing costs, difficulty sealing, limited protection levels, multiple joints during long-distance transmission, heat generation at the joints, and high costs. Traditional low-voltage cables use cylindrical conductors composed of multiple strands of wire, which suffer from poor heat dissipation, increased temperatures, and low conductor utilization. For high currents, multiple cables can only be connected in parallel, requiring numerous accessories, hindering heat dissipation, and leading to uneven current distribution, difficult end connections, and excessive cable waste. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a C-type high-current flexible busbar suitable for large-current and long-distance transmission of electric energy. It can solve the problems of the current low-voltage busbar duct with many joints, easy heating at the joints, difficulty in installation, and unsuitability for long-distance transmission. At the same time, it can also solve the problem of uneven current distribution when multiple cables are connected in parallel when traditional cables transmit large currents.

[0004] The object of the present invention is achieved like this:

[0005] The C-shaped high-current flexible busbar of this invention features flexible cable-type copper conductors arranged side by side in a C-shape. The conductors are covered with an insulation layer and then an outer sheath. Metal armor can be added between the insulation layer and the outer sheath if required for tensile strength or by the user. The busbar has a hollow "C"-shaped cross-section. Its main body is flexible and bendable, and it can be manufactured in long, continuous sections to reduce intermediate joints.

[0006] It comprises a flexible cable-type copper conductor with a C-shaped cross section, which is composed of a plurality of copper cores arranged in parallel. That is, the plurality of copper cores are arranged in parallel, and the cross section of the copper cores after being arranged in parallel is C-shaped.

[0007] The flexible cable-type copper conductor is entirely covered with an insulating layer, and the cross section of the insulating layer is C-shaped.

[0008] The outer sheath is entirely covered on the outside of the insulating layer, and the cross section of the outer sheath is C-shaped.

[0009] A metal armor layer may also be provided between the insulation layer and the outer sheath.

[0010] The flexible cable-type copper conductor is made of copper.

[0011] The material of the insulating layer can be composite insulating materials such as polyethylene, polyvinyl chloride, cross-linked polyethylene, rubber, etc.

[0012] The material of the metal armor is aluminum alloy, stainless steel, etc.

[0013] The outer sheath can be made of polyethylene, polyurethane, polyolefin, rubber and other materials.

[0014] The advantages of the present invention are that the copper cores of the C-shaped high-current flexible busbar conductor are arranged side by side in a C shape, have a large current carrying capacity, good heat dissipation performance, and occupy a small space.

[0015] The overall cross-section of the C-type high-current flexible busbar is a "C"-shaped hollow structure, and the hollow heat dissipation duct facilitates heat dissipation.

[0016] The C-type high-current flexible busbar body is flexible and bendable, and can be made into long continuous sections to reduce intermediate joints. It is suitable for power transmission under complex laying conditions and long distances.

[0017] This product was developed to meet the practical needs of low-voltage power transmission, such as increasing rated currents, long transmission distances, complex installation conditions, and confined spaces. It addresses the numerous joints in low-voltage bus ducts, which can easily overheat, are difficult to install, and are unsuitable for long-distance transmission. It also addresses the uneven current distribution caused by multiple cables connected in parallel when transmitting high currents through traditional cables. It is suitable for high-current, long-distance power transmission and offers a cost-effective advantage over traditional bus ducts and cables.

[0018] The present invention uses flexible copper cables arranged in a C-shape as conductors, with the conductors being entirely covered with an insulating layer. Metal armor can be added to the outside of the insulating layer according to actual conditions and customer needs, and the armor is entirely covered with an outer sheath. The flexible copper cables arranged in a C-shape have strong heat dissipation performance and high copper material utilization. They can effectively solve the problem of low conductor utilization in low-voltage bus ducts and traditional cables. They can also solve the problems of low-voltage bus ducts having many joints, easy heating at the joints, difficulty in installation, and unsuitability for long-distance transmission. At the same time, they can solve the problem of uneven current distribution when multiple cables are connected in parallel when traditional cables transmit large currents. They have high cost-effectiveness, reliable safety performance, and are maintenance-free. BRIEF DESCRIPTION OF THE DRAWINGS
