Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy cables, in particular to a fireproof and high temperature resistant aluminum alloy cable. Background Art

[0002] At present, most domestic wire and cable manufacturers have taken the lead in developing aluminum alloy power cables, and have made major technological breakthroughs in safety performance, electrical performance and mechanical performance, fully meeting the requirements of current national standards. When the cross-sectional area of ​​the aluminum alloy conductor of the aluminum alloy cable is 1.5 times that of the copper core, the two can achieve comparable electrical performance. Under the condition of comparable electrical performance, the advantages of the aluminum alloy cable itself will be more obvious. The cost is low, and the direct purchase cost is 30-40% lower than that of copper cables. It can save more than 20% of installation and construction costs for general buildings, and more than 40% for large-span buildings. It is light in weight, only half of the equivalent copper cable, and easy to transport and lay. For large and medium-sized projects, the use of aluminum alloy cables can achieve comprehensive savings in funds, manpower and material resources.

[0003] However, the existing highway tunnel power cables need to be changed into different applicable power cables according to different geographical environments in actual use. When the aluminum alloy cable is conducting, the temperature of the external environment and the heat generated by its own conduction increase the temperature of the aluminum alloy conductor. The cable is prone to burn when it is at high temperature or a fire occurs. In addition, damage to the cable skin will cause electrical fires, causing greater losses to people.

[0004] To this end, we propose a fire-proof and high-temperature resistant aluminum alloy cable. Utility Model Content

[0005] The main purpose of the utility model is to provide a fireproof and high temperature resistant aluminum alloy cable. Through the design of the copper ring and the protective sleeve, the internal part is protected and fireproof and high temperature resistant.

[0022] The inner wall of the protective sleeve 2 is provided with a first steel wire armor layer 7; the inner side of the first steel wire armor layer 7 is provided with a second steel wire armor layer 9, and the first steel wire armor layer 7 and the second steel wire armor layer 9 are both made of steel belts; the protective sleeve 2 is a horizontally arranged circular tubular structure, and the steel belts are arranged in a circular array with the center of the protective sleeve 2 as the center.

[0023] An anti-wear layer 8 is provided between the first steel wire armor layer 7 and the second steel wire armor layer 9, and an inner lining layer 10 is provided on the inner wall of the second steel wire armor layer 9; a plastic reinforced protective layer 11 is provided on the inner wall of the inner lining layer 10, an alloy lead sheath 12 is provided on the inner wall of the plastic reinforced protective layer 11, and a cable core 13 is provided on the inner wall of the alloy lead sheath 12.

[0024] It should be noted that the utility model is a fireproof and high-temperature resistant aluminum alloy cable. When in use, the protective sleeve 2 can provide protection for the interior. At the same time, by equidistantly arranging multiple groups of copper rings 1 installed on the protective sleeve 2, not only the protective sleeve 2 is protected, but also the surface damage of the aluminum alloy cable when it is bent multiple times can be prevented. The copper ring 1 can also quickly dissipate heat for the aluminum alloy cable. The first connecting strip 3 and the second connecting strip 4 are interlocked with each other. At this time, under the mutual cooperation of the elastic clips 5, the first connecting strip 3 and the second connecting strip 4 can also be firmly connected, so that the copper ring 1 and the protective sleeve 2 are firmly connected.
