Composite insulators are easy to form and have a variety of umbrella structures. The parameters describing the composite insulator umbrella structure include the morphological parameters of the umbrella skirt, such as the inclination of the umbrella skirt, and the extension ratio. , Such as isometric umbrellas, large-small umbrellas, large-small-small-medium-small-small umbrellas, etc.

There is no edge under the umbrella of the composite insulator, and the arrangement of umbrellas of different sizes has little effect on the pollution of the insulator, but it has a significant impact on the anti-icing performance. Too large a umbrella will make the insulator more easily bridged by the ice edge, resulting in a drop in ice flash voltage.

The composite insulator is composed of a core rod, an umbrella skirt sheath and a connection fitting. The material of the core rod is glass fiber reinforced plastic, which is used to provide the mechanical properties of the insulator. The sheath is connected to the surface of the core rod by an adhesive to protect the core rod. The connection hardware is located at both ends of the composite insulator and plays a role in connecting the composite insulator to the tower. The role of metal fittings.

A slot is first sawn through the core rod, and the slotted core rod is inserted into the inner hole of the metal fitting. A conical wedge is pressed into the mandrel groove to cause a certain friction between the surface of the mandrel and the inner wall of the metal fitting, so that the composite insulator can bear a certain mechanical tensile load.

After the core rod is sleeved into the inner hole of the metal fitting. A plurality of conical wedges are pressed between the core rod and the inner hole of the metal fitting. Make a certain friction between the hardware and the wedge and the core rod. The composite insulator can bear a certain mechanical tensile load.
