Embodiment Construction

[0030] In the following description, many specific details are explained in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0031] The purpose of lightning protection grounding makes the lightning current smoothly enter the ground. In order to reduce the ground voltage, the grounding resistance should not be greater than 10Ω under possible conditions. The invention reduces the grounding resistance value by increasing the surface area of ​​the grounding wire. Specifically, the present invention increases the surface area of ​​the ground wire by forming a pattern on the surface of the ground wire, thereby reducing the ground resistance value without increasing ...

Abstract

The invention relates to a wire with an increased surface area and a fabrication method of the wire. The wire with the increased surface area comprises a wire core part and a wire surface part, wherein the wire core part is made of metal, and a surface texture part is arranged on the wire surface part. By rolling textures on a surface of a ground wire, the surface area of the wire can be increased, and thus, the ground resistance is reduced on the condition that the usage amount of the metal wire is not increased; and moreover, the ground wire with the textures on the surface can be more closely in contact with surrounding soil when being buried in the soil, and rapid discharge is facilitated.

Description

Technical field [0001] The invention relates to the field of grounding wire manufacturing, in particular to a grounding wire with an enlarged surface area and a manufacturing method thereof. Background technique [0002] Whether it is working grounding, lightning protection grounding or protective grounding, metal wires are used. During the grounding construction process, grounding resistance needs to be considered. The grounding resistance value is related to the soil conductivity, the shape, size and layout of the grounding body, current frequency and other factors. Taking lightning protection grounding as an example, in order to meet the requirements of grounding resistance, it is usually necessary to determine the shape, size, quantity and arrangement of grounding bodies that should be buried. For areas with high soil resistivity (such as mountainous areas), in order to save metal materials , It is necessary to take measures to improve the conductivity of the soil, filling ...
