All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
In a specific embodiment, as shown in fig. 1, a 10kV prefabricated outdoor terminal comprises a silicon rubber insulating sleeve 1, a cable insulating cylinder 2, a cable insulating shield 3, a waterproof terminal 4 and a dustproof insulating enclosure 5;
waterproof terminal 4 is located dustproof insulating closed cover 5, and dustproof insulating closed cover 5 connects silicon rubber insulating cover 1, and cable insulation section of thick bamboo 2 is located silicon rubber insulating cover 1 inside, and 3 connecting cable insulation section of thick bamboos of cable insulation shielding 2 silicon rubber insulating cover 1 surfaces are provided with hydrophobic nanometer silica coating. The thickness of the silicon rubber insulating sleeve 1 is more than or equal to 5 mm. And the international IEC standard is met. The silicon rubber insulating sleeve 1 isolates and seals the cable core inside, the cable core penetrates through the cable insulating cylinder 2, and the cable insulating shield 3 is used for sealing the cable insulating cylinder 2.
In this embodiment, the nanosilica coating is hydrophobic due to its hydrophobicity. Dissolved in caustic potash (sodium). Insoluble in water and acids. Is nontoxic. Is tasteless. Has no corrosiveness. No combustion and no oxidation. Does not decompose at high temperature. Removing sodium ions from diluted sodium silicate by ion exchange, adding hydrochloric acid for acid-heat reflux concentration, adding a dimethyl dichlorosilane monomer solvent for hydrophobization, removing the solvent and drying to obtain the sodium silicate. It is mainly used as silicon rubber reinforcing agent, plastic filler, thickening agent of paint and printing ink, etc. Due to the existence of the super-hydrophobic nano-silica coating, the adhesion force between rainwater and the outer surface of the silicon rubber is very low, and the rainwater can easily roll away from the outer surface of the silicon rubber and take away dust on the outer surface of the silicon rubber under the disturbance of wind, so that the lotus leaf self-cleaning effect is realized.
