What problems does the disc suspension composite insulator solve?

Due to its good anti-pollution ability, porcelain composite insulators can reduce the number of pieces used and thus reduce the string length, which can lower the tower height. The light weight of porcelain composite insulators also enhances the tower and line’s ability to withstand ice loads, saving a lot of steel and land area. If large-tonnage porcelain (glass) composite insulators can be developed, they will have greater significance for ultra-high voltage project construction. The problem solved by high-strength porcelain core composite umbrella-skirt anti-pollution disc suspension composite insulators is that traditional insulators are easily contaminated in high humidity environments, which leads to discharge and accidents. Therefore, this new type of insulator has great potential for application.

1、Solves the problem of pollution and flashover of porcelain and glass insulators.
With the rapid development of economic construction, atmospheric and industrial environmental pollution is increasingly severe. Under moist weather conditions such as rain, fog, frost, and dew in nature, soluble substances in dirt on the surface of porcelain and glass insulators will gradually dissolve in water, forming a conductive water film on the surface of the insulator. If the insulator is heavily contaminated and fully dampened, intense local discharge may occur, which can lead to equipment flashover accidents.

Porcelain composite insulators are processed with a special technique on the porcelain plate surface and related interfaces. The silicon rubber composite jacket is molded by a tight wrapping and vulcanization process to ensure product quality. As the silicon rubber composite jacket has good water repellency and transferability, it has strong resistance to pollution and flashover.

2、Solve the problem of "brittle break" of ordinary rod type suspension composite insulator

According to relevant information: In the mechanical damage of organic composite insulators, the "brittle break" of the core rod accounts for 60% of the core rod fracture accidents that have occurred, and 35% of all mechanical accidents. The "brittle break" of mandrel has become the most serious accident of organic composite insulators. The mandrel of porcelain composite insulator is made of high strength porcelain, which solves the problem of "brittle break" of mandrel of common rod type suspended composite insulator.

3、To solve the problem that composite insulators can not be used for tensile string

At present, China's composite insulators are not used much on tensioning strings, mainly because of concerns about the mechanical strength of composite insulators, after all, China's synthetic insulators have less operating experience than foreign countries. In particular, after the breakage of organic composite insulators on the high voltage line, some composite insulators used on the tension insulator string are replaced with porcelain or glass insulators to ensure stable and reliable mechanical strength.

The high-strength porcelain plate used in the porcelain composite insulator is provided by the famous disk-shaped suspension porcelain insulator manufacturer. It adopts the mature pouring process of the porcelain insulator, adopts the steel foot and iron cap connection, and the connection method is the same as that of the porcelain insulator. It can be used on the tensioning string like ordinary porcelain insulators.
