Composite line insulators / composite crossarm insulators

A brief introduction about our Hot Sale!! High Voltage Polymer insulator :
This kind of product is applied to urban net technical reconstruction; it can effectively boost power transmission using urban narrow corridor areas, lower tower height, save many pecuniary resources and materials. Because of the high bending strength, it can avoid the porcelain cross-arm having continuous fracture accidents easily, with good anti-pollution, and the products of porcelain cross-arm cannot be instead of it.
