Structural composition
Glass insulators are usually composed of iron caps, tempered glass pieces, and steel feet, which are bonded together with cement adhesive.
The shape design of the aerodynamic insulator conforms to the principle of aerodynamics.
The shape and layout of the umbrella skirt can effectively reduce wind resistance, and the wind load it bears is significantly reduced compared to traditional insulators in strong wind environments. For example, the use of aerodynamic insulators on transmission lines in windy coastal areas or high mountain tuyere locations can greatly reduce the lateral wind pressure on towers.
The special shape of this insulator can also guide the air flow, so that the air flow on the surface of the insulator is more smooth. When the air flow passes by, it can quickly take away the water vapor generated on the surface of the insulator due to moisture and other reasons, and reduce the moisture on the surface of the insulator, thereby reducing the flashover risk caused by the humid environment.
