Development And Evolution Of Epoxy Resin Insulators
high voltage standoff insulators is an insulating control that plays an important role in overhead transmission lines, that is, it supports the conductors and prevents the current from returning to the ground. In the past, insulators were mostly used for electric poles, but now they have gradually developed into disc-shaped insulators hung at one end of the high-voltage wire connection tower, usually made of ceramic or glass. high voltage epoxy It is necessary to ensure that various electromechanical stresses remain unchanged when the environment and electrical load conditions change, otherwise they will not only fail to play their due role, but will also damage the service life of the entire line.
Shangpu Consulting Machinery Industry Analyst pointed out that in my country's epoxy resin insulator industry, in addition to the relatively stable operation of lightning arresters, pillars and hollow high voltage epoxy resin have made great progress, and casing products have the most problems. According to statistics, the failure rate of high voltage standoff is 0.3‰, of which the high voltage part is 0.1‰, and the glass and porcelain insulators are 0.2‰. Therefore, each manufacturer needs to further strengthen quality control in terms of design, raw materials, process, etc., and strengthen communication with demand parties to develop new products that continuously meet the needs of power grid construction and make certain contributions to the construction of smart grids.
In the process of rapid development, the insulator industry still has two problems that need to be solved: first, the scale of enterprises is small, the industry concentration is low, and the whole industry is relatively "scattered"; second, the research and development of basic materials affects the progress of insulator technology, and it is still necessary to increase research and development efforts. After continuous development in recent years, the quality level of my country's insulator products has been greatly improved, and it has well adapted to the requirements of my country's power grid development. Its manufacturing level has reached the international leading level, and its operating performance is getting better and better.
According to the "2011 China High Voltage Insulator Industry Analysis and Investment Prospect Forecast Report" released by Shangpu Consulting, the rapid development of my country's power industry in recent years has brought unprecedented opportunities for the development of the insulator industry. Industry enterprises should seize the opportunity, rely on technological progress and strengthen quality management, and fully meet the needs of the power industry, especially the market demand for high-end hollow porcelain insulators and bushing products. With the deepening of my country's urban network transformation and smart grid construction, the demand for insulators has increased dramatically, the market potential is huge, and the development prospects are promising.
