[0025] The insulating component 3 includes a connecting piece 301, a surface microstructure 302, a connecting ring 303, a groove 304, a microgroove array 305, and a skirt 306. The connecting ring 303 is fixedly connected to the inside of the skirt 306. The surface microstructure 302 is fixedly connected to the surface of the connecting ring 303. The groove 304 is formed on the surface of the connecting ring 303. The microgroove array 305 is fixedly connected to the front side of the connecting ring 303. The rearmost skirt 306 is fixedly connected to the front side of the foremost reinforcing rib 203. There are six microgroove arrays 305, which are distributed in a ring at equal intervals on the front side of the connecting ring 303. The microgroove arrays 305 guide rainwater to form a high-speed scouring effect. Centrifugal force is used to remove surface contaminants. By setting a coating layer and coordinating with surface components, the composite insulator can avoid being affected by climate and temperature and humidity factors, reducing the probability of skirt powdering. The setting of multiple microgroove arrays 305 increases the performance. The surface microstructure 302 is designed in the shape of a lotus leaf, which can reduce the adhesion of moisture and contaminants and reduce the risk of flashover. The connecting piece 301 is fixedly connected to the surface of the connecting post 201 near the front. The skirt 306 is fixedly connected to the surface of the connecting post 201. During use, the surface of the skirt 306 needs to be treated, including spraying with paint and careful cleaning to remove surface dust and impurities, which can increase the adhesion between the paint and the surface of the insulator.

The connecting column 201 is fixedly connected to the inside of the connecting plate 1, the connecting plate 202 is fixedly connected to the front of the connecting column 201, and the reinforcing rib 203 is fixedly connected to the inside of the connecting plate 202.

[0027] In use, a connecting post 201 is provided inside the connecting plate 1. The surface of the connecting post 201 is provided with a connecting disc 202 and a reinforcing rib 203. The connecting disc 202 and the reinforcing rib 203 are used to connect the last umbrella skirt 306. The use of the reinforcing rib 203 increases the connection strength. During use, the surface of the umbrella skirt 306 needs to be treated by spraying paint and carefully cleaning to remove surface dust and impurities. This increases the adhesion between the paint and the insulator surface. Vacuum spraying equipment is used during spraying. The coating is evenly sprayed onto the surface of the umbrella skirt 306. It can also be sprayed onto the surface of the connecting piece 301. The surface microstructure 302 of the connecting ring piece 303 reduces the adhesion of moisture and contaminants, reducing the risk of flashover. Furthermore, a microgroove array 305 is provided on the surface of the connecting ring piece 303. The microgroove array 305 guides rainwater to form a high-speed scouring effect, using centrifugal force to remove surface dirt. By setting the coating layer and cooperating with the surface components, the composite insulator can be prevented from being affected by climate and temperature and humidity factors, reducing the probability of umbrella skirt powdering, resulting in good performance during use.
