[0024] A disc-shaped suspension insulating component 5 is fixedly connected inside the steel cap 1 and the glass umbrella tray 2. A composite umbrella cover 6 is fixedly connected to the outside of the disc-shaped suspension insulating component 5. An anti-icing umbrella edge 7 is fixedly connected to one side of the composite umbrella cover 6. Steel feet 8 are installed inside both the steel cap 1 and the glass umbrella tray 2.

[0026] As attached Figure 3 , 4 As shown, the composite umbrella cover 6 has an anti-ultraviolet layer 9, a heat insulation layer 10, and an insulation reinforcement layer 11 arranged sequentially from the outside to the inside. The thickness of the insulation reinforcement layer 11, the anti-ultraviolet layer 9, and the heat insulation layer 10 increases sequentially, thereby improving the performance of the composite umbrella cover 6.

[0027] As attached Figure 4 As shown, the UV-resistant layer 9 is made of silicone rubber with added nano-level UV absorbers, and the heat insulation layer 10 can be made of ceramic fiber to enhance the UV resistance and further improve the heat insulation performance.

[0028] As attached Figure 4As shown, the insulating reinforcement layer 11 is a glass fiber reinforced resin insulating material doped with conductive fibers, used to uniformly distribute the electric field and improve the insulation performance.

[0029] As attached Figures 1-3 As shown, the edge of the glass umbrella disk 2 is arc-shaped to reduce wind resistance and reduce vibration caused by wind.

[0030] Working principle of this utility model: In use, the three-umbrella type anti-icing glass composite insulator provided by this utility model has a steel cap 1 located at the top of the insulator, serving a connecting and fixing function. Together with the glass umbrella disc 2, it encloses the internal disc-shaped suspension insulator 5 and steel feet 8. A fixing groove 3 on the top surface is used to install locking pins 4, ensuring the insulator is firmly fixed to the overhead line. The glass umbrella disc 2 is fixedly connected to the bottom of the steel cap 1, increasing the creepage distance of the insulator and improving insulation performance. Its curved edges reduce wind resistance and vibration caused by wind. The fixing groove 3 provides an installation position for the locking pins 4, ensuring the stability of the locking pin installation. The locking pins 4 are made of high-strength, corrosion-resistant material, improving the reliability of the connection between the insulator and the overhead line. The disc-shaped suspension insulator 5 is made of glass fiber reinforced resin insulation material and is the core insulation component of the insulator, providing excellent insulation performance for the overhead line and preventing current leakage.

[0031] The UV-resistant layer 9, located on the outermost layer of the composite umbrella sleeve 6, is made of silicone rubber with added nano-level UV absorbers. Its function is to absorb and block UV rays, preventing their aging effects on the internal materials of the composite umbrella sleeve 6 and the disc-type suspension insulator 5, thus extending the insulator's service life. The heat insulation layer 10, made of ceramic fiber, is located between the UV-resistant layer 9 and the insulation reinforcement layer 11. Its main function is to prevent heat transfer to the internal structure of the insulator in high-temperature environments, avoiding performance degradation of internal components such as the disc-type suspension insulator 5 due to excessive temperature. In cold environments, it reduces internal heat loss, preventing problems such as icing due to low temperatures. This is achieved through the insulation reinforcement layer 11. The glass fiber reinforced resin insulation material, incorporating conductive fibers, is located in the innermost layer of the composite umbrella sleeve 6. This provides additional insulation protection for the insulator, enhancing its overall insulation performance. Furthermore, the incorporated conductive fibers evenly distribute the electric field, improving the stability of the insulation performance. The anti-icing umbrella edge 7 reduces ice adhesion, preventing ice formation on the insulator surface and improving the insulator's reliability in cold weather. The steel feet 8, installed inside the steel cap 1 and the glass umbrella disc 2, connect the conductors. Their surface is galvanized to prevent rust, and the connection points with the steel cap 1 and the glass umbrella disc 2 are sealed to prevent moisture ingress, ensuring the insulator's insulation performance.

[0032] In overhead lines, the three-umbrella anti-icing glass composite insulator is firmly fixed to the tower by steel cap 1 and locking pin 4. The disc-shaped suspension insulator 5 provides the main insulation performance and prevents current leakage to grounding components such as the tower. The various layers in the composite umbrella sleeve 6 work together. The UV-resistant layer 9 protects the internal materials from UV damage. The heat insulation layer 10 regulates the internal temperature of the insulator. The insulation reinforcement layer 11 further improves the insulation performance. The anti-icing umbrella edge 7 prevents ice formation in cold weather, reducing the risk of insulation performance degradation and flashover caused by icing. The arc-shaped edge of the glass umbrella disc 2 reduces wind resistance and vibration. The steel feet 8 ensure a reliable connection with the conductor. All parts of the structure work together to ensure the safe and stable operation of the power system.
