working principle of anti-pollution insulator
There is no difference in material between the ordinary insulator and anti-pollution insulator, but it can be seen from the outside whether it is pollution type or ordinary type! Anti-pollution type high voltage insulator comprises more shed or graves.
Should confirm this, insulator which can adapt to all kinds of filthy conditions does not exist. In the same area, the amount of the contamination insulators of different shapes are different, the anti-pollution insulator is through improvements in the design and technology to meet anti-pollution requirements.
Insulator shape and installation affect the amount of the contamination. Air flow rate and shape characteristics determine the characteristics of the airflow around the insulator. It was found that on a smooth surface without forming a vortex gets small amount of the contamination, the opposite is easy to form a vortex and turbulence in the airflow velocity and lower parts of favor deposition filthy. anti-pollution insulator is the use of this principle, designed to meet the aerodynamics of the sheds, to achieve stain-resistant properties, such as 80KN fog type zinc sleeve suspension insulator.
