Piezoelectric Material in Liquid Form Discovered For The First Time

Recently, chemists at Michigan State University have observed the piezoelectric effect in a liquid for the first time. The research team pointed out that liquid piezoelectric materials are more environmentally friendly than solid piezoelectric materials and are expected to "show their talents" in many fields. The related research was published in the latest issue of "Physical Chemistry Letters".

Insulator flash cause analysis

Flashover mainly includes pollution flashover, fog flashover and icing, including rain, dew, frost, fog, wind and other climatic effects, or dust, waste gas, natural salt and alkali, dust, bird droppings and other pollution. The process of insulator contamination is usually gradual, but it can also be rapid.

What are the advantages of glass insulators?

Glass insulator is used to support the wire and make it insulated device, it is made of glass, currently used in the route is widely toughened glass insulator. It is generally made of glass and porcelain, and is one of the key components of high-voltage transmission lines, and its performance directly affects the operation safety of the entire transmission line. Glass insulators are widely used because of the characteristics of zero self-breaking and easy maintenance. Now let's talk about the ad

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 s
