Polymer Insulators

Polymer Insulators

Polymer insulators can be divided into: line post insulators,power station insulators and electrical insulators. According to different structure and functions,it can also be divided into rod or brace suspension insulator, pin Polymer insulators, cross-arm polymer insulators, post polymer insulator, wind-proof partial polymer insulators, etc.

In the 1980s, Tsinghua University, Wuhan Water Conservancy and Electric Power College and other units began the development of Polymer insulator under the support of the National “Seventh Five-Year Plan”. Both units of the umbrella skirt materials were made of high temperature vulcanized silicone rubber, gold fittings and epoxy glass core. The connection method of the rod adopts different technical routes, and Tsinghua University adopts the inner wedge structure. Wuhan Water Conservancy and Electric Power College adopts an outer wedge structure.

The scientific and technological achievements of the two schools were transferred to enterprises and converted into productivity. Initially, the power operation department had doubts about the performance of the Polymer insulator, and was cautious about the operation of the hanging network. Only a small number of samples were placed on the unimportant voltage level below 110 kV for live test. In 1990, the large-scale pollution flashover accident occurred in North China. The Polymer insulators tested showed excellent anti-soil flashing ability and were loved by power operation units. Many departments took the initiative to adopt this new technology and expanded the scale and scope of trial operation. The pollution-resistant flashing capacity of the transmission and distribution lines and the work of cleaning the line are alleviated, which is welcomed by the power operation unit.

After several years of operation assessment, the power authority has confirmed that the Polymer insulator is a new anti-pollution technology and has begun to be applied at voltage levels above 110kV.

As the best professional polymer insulators manufacturer,ZX Insulator take the quality and lead time on the first important position,to make sure customers can use the best insulators in the earliest time.
