High voltage cross arm insulator

High voltage cross arm insulator the porcelain cross arm insulator has the function of fixing the conductors and insulation to the ground, and the composite cross arm insulator also have this kind of function.

High voltage cross arm insulator

On the basis of material, the high voltage cross arm insulator can be divided into two kinds: one is the composite cross arm insulator, which the material of it is silicon rubber and recent years the material of silicon rubber is more and more widely used, the other is the porcelain or the ceramic cross arm insulator.

In recently years, more and more countries are preferred to use high voltage composite cross arm insulator, and fewer countries are still using the high voltage porcelain cross arm insulator. There are reasons for this phenomenon, there is an outstanding part in using the composite cross arm insulator, the material and construction cost can be saved when using the composite cross arm insulator. It can also save the cost on the steel and the great money used on the whole structure.

High voltage cross arm insulator, with the development of the technology, the iron cross arm and the wooden cross arm can be fully installed or partly replaced by the composite cross arm insulator.
