Mold-proof, antibacterial and anti-corrosion cable used for power transmission

Abstract

The invention discloses a mold-proof, antibacterial and anti-corrosion cable used for power transmission. The cable comprises three conductors (1). An inner isolating layer (2) wrapped by a mica sub-band is arranged outside each conductor (1). An insulating layer (3) is arranged outside each inner isolating layer (2). An outer isolating layer (4) wrapped by a mica sub-band and aramid fiber is arranged outside the insulating layers (3) of the three conductors (1). A polyethylene sheath (5) and a mold-proof polypeptide thin film layer (7) sequentially wrap the outer isolating layer (4). A fire-resistant filling material (6) is arranged between the insulating layers (3) of the three conductors and the outer isolating layer (4) wrapped by the mica sub-band and the aramid fiber. The developed cable has extremely strong antibacterial and anti-corrosion functions, the preparation mode is easy and convenient, and the effect can be achieved without special processes. The cable has the advantages of being low in input, high in yield and capable of saving resources.

Description

technical field [0001] The invention mainly relates to a cable, in particular to a cable with anti-mildew, anti-bacteria and anti-corrosion properties for power transmission. Background technique [0002] With the development of human society, human beings are inseparable from electricity all the time. Cables, which play an increasingly important role in modern life, undertake the important mission of delivering electrical energy to where it is needed. [0003] However, the use environment of cables is usually relatively harsh. For example, if the cables are buried underground, the cables are prone to mold and corrosion, which may cause the cables to break or short circuit, thereby affecting the transmission of power. At present, the cable trench commonly used for cable transportation is used to bury cables, but the trench cover is an ordinary concrete trench cover. The function of the trench cover is mainly to cover the cable trench, preventing water and debris from fallin...

Problems solved by technology

The aramid structure has two layers of skin and core. The high strength and high modulus of aramid fiber is mainly determined by the inner high crystallization core layer. In the application process, especially in some humid or outdoor exposure application environments, aramid fiber It is easy to mold in the material, and when a large amount of mold gathers, it will cause damage to the aramid fiber filament, thereby reducing the quality of the product it is applied to

Therefore, when people produce aramid fibers, they need to be treated with mildew and antibacterial treatment. In the traditional treatment method, one is to add antibacterial agents during the spinning process of aramid fibers, so that the antibacterial agents can be integrated into the aramid fibers. The process of the method is relatively complicated and the cost is high. At the same time, because the antibacterial agent exists inside the aramid fiber, it will destroy the regularity of the molecules, affect the crystallization of the aramid, and greatly reduce the tensile strength of the aramid fiber; another The first is to graft antibacterial agents on the surface of aramid fibers through chemical reactions, but this method requires a long processing time and high cost. Multi-active groups, when the antibacterial agent is grafted onto the aramid fiber, this reaction process will have a great impact on the performance of the aramid fiber, and also greatly reduce the tensile strength of the aramid fiber
