220kV Polymer Station Post Insulator With Flange

Advanced Polymer Material: Made of high-grade polymer components, this insulator demonstrates exceptional electrical insulating qualities, ensuring reliable operation across a range of operating circumstances.

Flange Design: The insulator's stability is improved by the incorporated flange, allowing for stable mounting and efficient load distribution, particularly under high-stress circumstances.

Hardware That Is Resistant to Corrosion: The accompanying flange and hardware are corrosion-resistant, ensuring a long service life and requiring less maintenance.
 

The application of porcelain insulators has a history of more than 100 years, glass insulator applications than porcelain insulators, although short, but also known as a long history, composite insulator application history is not long, but also 30 years of network operation time. It can be argued that the insulator manufacturing and use of technology is relatively mature, but still in the continuous updating and development of porcelain and glass insulators in the shape of the structure of the century has not undergone a revolutionary change, but the materials, processes, structural improvements have not stopped, in the continuous progress is highlighted in the following aspects:

(1) with the increase in transmission voltage level, the single insulator electrical and mechanical destruction of load requirements Increasingly high, has been able to produce electromechanical destruction load of 300 kN, 40 kN500 kN to 800 kN of porcelain insulators

(2) due to the improvement of the manufacturing process and materials, glass insulators have been a substantial reduction in the rate of self-explosion, which is of great significance to improve the reliability of glass insulators.

(3) The improvement of insulator shape is an eternal issue, the shape of the insulator is a regional applicability, it is impossible to find a shape of the insulator in the world are the best use of insulators. Countries are developing insulators suitable for special areas, in recent years the emergence of three-layer umbrella insulators is a typical example

(4) the use of isometric pressure process to produce porcelain insulators to improve the strength of a great deal, and in the manufacture of large-size pillar insulators and porcelain bushings, the process has gradually replaced the tendency of the ordinary wet production process.
