Composite cross arm insulator can effectively use the narrow corridor open pressure transmission, which suitable for city network technical transformation.
It can reduce the pole tower height and save a large amount of manpower, material and financial resources.
Because of its high bending strength, it can prevent the cascade failure like the porcelain cross arm.
It has the advantages of small volume, light weight, shock, shock resistance ability, no need manual cleaning to guarantee safe operation.
This composite cross-arm insulator is applicable to urban network transformation. It is capable of utilizing the narrow corridors for boost power transmission, which can reduce tower height and thus saves a lot of money. Due to its high bending strength. the cascading failure, which often arises in power lines using porcelain cross-arm insulators. can be avoided. In addition, this product has stain resistance, making it irreplaceable by porcelain cross arm product.
