Description

Technology Field

[0001] The present invention relates to a grounding wire installation device for a power distribution line in the field of power distribution technology, and more specifically, to a grounding wire installation device that supports a grounding wire connected to a cable of a power distribution line, thereby preventing the grounding wire from moving due to external force or wind and getting caught or rubbed against a utility pole or other cable, which would cause the sheath to be damaged or cut, thereby preventing leakage current caused by damage or cut of the sheath, thereby preventing safety accidents caused by leakage current, and reducing maintenance costs and time caused by damage or cut of the sheath. Background Technology

[0003] Generally, electricity produced at power plants travels along the transmission lines to substations, where it is lowered to a lower voltage and supplied to general buildings and factories via distribution lines. Additionally, a portion of the extra-high voltage supplied to substations is reduced to a usable voltage through pole-mounted transformers and surface-mounted transformers attached to utility poles, and then supplied to homes, shops, and small factories.

[0004] The transformers on these utility poles are devices that convert AC power supplied to one winding into AC power of a different voltage to the other winding through electromagnetic induction, and consist of an iron core and insulating materials such as insulating oil that form a single common magnetic circuit with the windings constituting the electrical circuit.

[0005] Cables, which are distribution lines connected to a substation, are connected to the aforementioned utility poles to guide electricity, and insulators having an insulating structure are installed on the utility poles, and cables are mounted or connected to the insulators to support the cables.

[0006] In addition, one end of a grounding wire is connected to the cable, which is a distribution line connected to the utility pole, to discharge electricity caused by leakage into the ground, and the other end of the grounding wire is connected to a discharge shaft (grounding rod) or discharge panel buried in the ground to discharge the leakage electricity into the ground.

[0007] However, conventional grounding wires connected to power distribution cables are susceptible to movement by wind or external forces, leading to friction with other utility poles or cables. This friction can cause damage to the wire shafts or lead to breakage, resulting in electrical leakage. Furthermore, the leakage can cause safety accidents and incur maintenance costs and time.

[0008] The aforementioned invention refers to background technology in the technical field to which the present invention belongs, and does not refer to prior art. Prior art literature
