What is the role of the insulator

    Commonly known as porcelain insulators, which is used to support wire insulator. Wires and insulators can guarantee cross arm, Tower has enough insulation. Pull it in operation should be able to withstand the load of the wire vertical and horizontal directions. It also suffers from the sun, rain, climate change and corrosive chemicals. Therefore, we must have good electrical insulator properties, but also have sufficient mechanical strength. Insulators for the safe operation of the line is good or bad is very important.

    Insulators can be classified according to the structure supporting insulator, suspension insulator, stain insulator insulators and bushings. Overhead lines used insulators, commonly used pin insulators, butterfly insulator, suspension insulator, porcelain cross arm, tension rod insulators and insulators. Electrical insulator flashover failure and breakdown two kinds. Flashover occurred in the insulator surface can be seen burn marks, usually do not lose insulation properties; breakdown occurs inside the insulator, between the iron by iron cap and pin ceramic body discharges, may not see signs of the appearance, but has lost its insulation properties, also It may be due to arcing insulator so completely destroyed. For the breakdown, should pay attention to discharge and burn marks Check iron foot.
