Ceramic insulators performance deficiencies which still exist

    Glass insulators have a zero value since the break characteristics. As long as the ground or in a helicopter observation can be, without registration sheet detection lever gradually reduce the labor intensity. Introduce the production line of products, annual run rate of 0.02-0.04% since the break, you can save the line maintenance costs. Arc resistance and vibration resistance performance is good. In operation lightning glass insulator suffered burns new surface remains smooth vitreous, and internal stress steel protective layer, so that it remains adequate insulation parts and mechanical strength. Altitude Insulator Selection and external insulation design, combined with China's first 750kV transmission line construction and high-altitude Qinghai-Tibet railway line construction along the proposed high-voltage transmission insulators selection and design of the outer insulation, ceramic insulators for altitude (ie, atmospheric pressure ) on insulator flashover characteristics of a large number of experiments. Insulators often occur in the use of a certain situation causes prompted in use can not be normal reality an important role and value, it needs to be resolved in a timely manner to ensure the safety and effectiveness of electrical equipment. In the insulator will appear in the case of the use of an unknown cause flashover, in this case, the researchers analyzed countries are constantly analyzing important causes and methods.
