Problems solved by technology

[0003] However, in recent years, the edge quality of the strip has been paid more and more attention by strip manufacturers. The cutting accuracy of the copper strip is getting higher and higher, but there will always be burrs on the edge of the copper strip after shearing, and the anti-interference performance is poor.

Abstract

The invention discloses a copper strip for a dry transformer. The copper strip comprises a poly(phthalazinone ether sulfone ketone) resin-based composite material layer, a Cdx / CdS-SiO2 composite thin film layer, a 3-chloropropyl polyhedral oligomeric silsesquioxane layer, a nanometer H3PW12O40 / TiO2 composite film layer, an anti-burr reinforced layer and a copper strip body, wherein the poly(phthalazinone ether sulfone ketone) resin-based composite material layer, the Cdx / CdS-SiO2 composite thin film layer, the 3-chloropropyl polyhedral oligomeric silsesquioxane layer, the nanometer H3PW12O40 / TiO2 composite film layer and the anti-burr reinforced layer are sequentially arranged on one surface of the copper strip body. Through the above mode, the edges of the sheared copper strip are free of burrs, and the copper strip is high in anti-interference performance.

Description

technical field [0001] The invention relates to the field of copper strips, in particular to a copper strip used for dry-type transformers. Background technique [0002] Copper strips are mainly used in the production of electrical components, lamp holders, battery caps, buttons, seals, and connectors, and are mainly used as electrical, thermal, and corrosion-resistant equipment. Such as electrical components, switches, gaskets, gaskets, electric vacuum devices, radiators, conductive base materials, and automotive water tanks, heat sinks, cylinder plates and other parts. [0003] However, in recent years, the edge quality of the strip has been paid more and more attention by strip manufacturers. The cutting accuracy of the copper strip is getting higher and higher, but there will always be burrs on the edge of the copper strip after shearing, and the anti-interference performance is poor. .
