Embodiment Construction

[0041] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail;

[0042] Such as figure 1 , 2 , a kind of coating method of the wire that is coated with Teflon coating, the coating method of insulator shown in 3, at first prepare the organic solvent of alcohols or ketones, wire is arranged in a straight line, insulator is strung into row; Insulator is coated with The method includes the following steps:

[0043] a), degrease

[0044] In order to obtain sufficient surface adhesion on the surface of the insulator, all the grease on the surface of the insulator 3 to be coated must first be removed; first use acetone to dissolve the grease on the surface of the insulator 3, and then use a heating device to heat the insulator 3 to 420-450°, so that the surface of the insulator 3 remains Alcohol or ketone organic solvents are completely volatile;

[0045] b), sandblasting

[0046] A sandblasting machine is used to form ...

Abstract

The invention relates to a coating method for a wire or an electrical insulator with a teflon coating, which relates to the technical field of transmission lines. The coating method for the electrical insulator (3) comprises the steps of degreasing, sand-blasting treatment, coating, drying and sintering. The coating method for the wire (1) comprises the steps of degreasing, coating adhesives and spraying the coatings. As the teflon has inadhesion property and moisture resistance, the aim of preventing serious icing can be fulfilled by spraying the teflon on the outsides of the wire and the electrical insulator, and the aim of preventing the pollution flashover can be fulfilled by spraying the teflon on the outside of the electrical insulator. As the teflon coating film has excellent heat resistance and low temperature resistance, the wire or electrical insulator sprayed with the teflon can work normally in a high-temperature environment in summer or a low-temperature environment in winter.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a method for coating wires and insulators coated with Teflon coating. Background technique [0002] As we all know, the main function of wires is to guide electric energy to achieve directional transmission. Wires can be divided into two categories according to their structures: one is called wires with a relatively simple structure and no outsourcing insulation; the other is outsourcing special insulation layer and armor The cables used in the power transmission and transformation system are called power cables, and the cables used in the communication system are called communication cables. High-voltage electric porcelain insulators are special insulators used to support or suspend high-voltage conductors to isolate the ground; therefore, various high-voltage power transmission and transformation equipment, especially high-voltage power transmission and transfo...
