Composite post insulator to defectively use the narrow corridor, applicable to open pressure city network technology, can reduce tower height, can save lots of human, material and financial resources, due to its high bending strength, can prevent porcelain cross arm cascade, is the porcelain of product, small volume, light weight, shock. impact resistant capability is strong, no artificial cleaning, to guarantee safe operation. This product adopts the overall design of the stick, compact structure, high quality and weight is the same level porcelain insulator and glass of 10, transportation is very convenient installation. Applicable to uncleanness, high mechanical drawing load, big span and compact lines. Lightning pressure than with dirt and glass ceramic insulators, improve level 30-50%.In -60~+200 degrees environment temperatures table performance, using the breakdown type design, operation without measurement of zero value/Electrical performance, high mechanical strength, internal bearing epoxy glass lead pulling tensile flexural strength than ordinary steel  twice, high intensity of ceramic materials of 8~10 times, effectively improve the reliability of the safe operation. Pollution resistant, good resistance, high mechanical strength, internal bearing epoxy glass lead pulling tensile flexural strength than ordinary steel twice, high intensity of ceramic materials of 8~10 times, effectively improve the reliability of the safe operation. Pollution resistant, good resistance, good resistant properties, its strength pollution flashover voltage tolerance and filthy wet tolerance for the same voltage up from the porcelain insulator 2-2.5 times. And don't need cleaning, can in heavy impurity to safe operation. Small volume, light weight, only for the porcelain insulator with voltage grade 1/6~1/9.The structure to be dexterous, convenient transportation and installation.
