  • COMPOSITE COATING AND PREPARATION METHOD THEREFOR, SILICONE RUBBER PROTECTIVE SLEEVE AND INSULATOR
    Publication number: 20260201176
    Abstract: A method of preparing the composite coating includes the steps of: coating an adhesive solution on a substrate to obtain a liquid film; embedding hydrophobically modified tetrapod-shaped zinc oxide powder into a surface of the liquid film and then embedding hydrophobically modified nano metal oxide powder into the surface of the liquid film, and fully curing the liquid film to obtain a composite coating having a micro-nano structure.

  • Insulator and power transmission line apparatus
    Patent number: 9196396
    Abstract: An insulator is disclosed, which includes an insulating surface. A part of the insulating surface is applied with a conductive coating having a specific resistivity. A conductive coating region having the specific resistivity and a nonconductive coating region are configured that: in a dry environment, no continuous conductive channel exists between upper and lower fittings of the insulator. The value of the leakage current that can be caused by the conductive coating region having the specific resistivity on the insulating surface enables the insulating surface to reach an ice-proof temperature in an icing climate condition. Also, a power transmission apparatus in which the insulator is adopted is disclosed. In an icing climate condition, the conductive coating can achieve the function of increasing the value of the leakage current on the surface of the insulator, so as to prevent the ice formation.
