[0002] Insulators are insulating components used in electrical equipment to support conductors of transmission lines and power equipment.
[0003] In the prior art, in power transmission lines, disc insulators are common insulating elements used to support conductive lines and isolate power equipment. In order to effectively prevent interference from electromagnetic waves and ensure the stability and safety of the lines, shielding rings are often provided in the disc insulators. The shielding rings are clamped inside the disc insulators and then fixedly connected to the flanges by bolts.
[0004] However, disc insulators are mostly used in outdoor high-altitude lines, and traditional shielding rings are fixed to flanges by bolts. When encountering heavy rain, water comes into contact with the bolts, which can easily cause corrosion of the bolts and affect the connection stability between the shielding ring and the flange.
