Polymeric Beam Insulators

  This product can effectively use cities’ narrow corridor area to enhance power transmission and reduce the tower height, and save a large amount of financial and material resources. Because of its high resistance bending strength, it can prevent the porcelain beams from being easily broken to cause the cascading accidents. Its anti-pollution performance is better, so it is not replaced by other porcelain beams.
