Embodiment Construction

[0035] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be interpreted as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may explicitly or implicitly include one or more of these features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0037] In the present invention, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection" and "fixation" should be understood in a broad sense, for exam...

Abstract

The invention discloses a bending-resistant and corrosion-resistant PVC power line and a preparation forming method thereof. The bending-resistant and corrosion-resistant PVC power line comprises a plurality of protection wires and an outer protection layer wrapping all the protection wires. Each protection wire comprises a wire body, and the wire body is sequentially sleeved with an anti-radiation layer, an insulating layer and an inner protection layer from inside to outside. The outer protective layer is sequentially sleeved with a PVDF layer, a braided layer, a bending-resistant layer andan outer protective layer from inside to outside. The power line provided by the invention has good bendability and corrosion resistance, so that the power line is suitable for being used in special environments such as chemical laboratories and the like.

Description

technical field [0001] The invention relates to the technical field of power cords, in particular to a bending-resistant and corrosion-resistant PVC power cord and a preparation method thereof. Background technique [0002] Power cords are wires that carry electricity. Usually the way of current transmission is point-to-point transmission. Power cords can be divided into AC power cords and DC power cords according to their uses. Usually, AC power cords are wires that pass through high-voltage alternating current. Due to the high voltage, such wires require uniform standards to obtain safety certification before they can be formally produced. The DC line basically passes DC with a lower voltage, so the safety requirements are not as strict as the AC line, but for safety reasons, countries still require unified safety certification. [0003] The structure of the power cord is not very complicated, but don’t simply see through it from the surface. If you study the power cord ...
