Abstract

The invention discloses an insulator with a diamond protective layer and a production method thereof. The insulator comprises an insulator body, wherein the part on the outer surface of the insulator body, which is not contacted with an electric wire, is fully deposited with the diamond protective layer, and the thickness of the diamond protective layer is 60 nanometers to 1000 nanometers; and the method for producing the insulator with the diamond protective layer comprises the following steps of: firstly, shielding the part which is arranged on the outer surface of the insulator body and contacted with the electric wire; secondly, producing the diamond protective layer on the outer surface of the insulator body through chemical vapor deposition to obtain the insulator. The insulator provided by the invention has good anti-pollution performance and excellent ability to resist ultraviolet light, and plays an important role in reducing the occurrence of pollution flashover accidents.

Description

technical field [0001] The invention relates to an insulator and a production method thereof, in particular to an insulator with a diamond protective layer and a production method thereof. Background technique [0002] Insulators are an indispensable part of power transmission and transformation equipment, and are closely related to the development of the national economy, especially the development of the power industry. With the continuous increase of the transmission capacity of transmission lines and the development of ultra-high voltage technology, the requirements for insulators are getting higher and higher. The performance of the currently used porcelain and glass insulators can no longer fully meet the needs of power operation and safety. In recent years, a new type of insulator-composite insulator has been developed. Composite insulators are composed of three parts: core rod, umbrella disk and metal terminal. Among them, the mandrel is generally made of epoxy gl...
