Product Description:
Different types of composite post insulators have different functions, and the structural height and creepage distance are also different. Composite post insulators are mainly used in substations, and have good hydrophobicity, aging resistance, tracking resistance and electrical corrosion resistance. , has high tensile strength and bending strength, high mechanical strength, good impact resistance, shock resistance and brittle fracture resistance, light weight, easy installation and maintenance, and the installation dimensions of the upper and lower ends are the same as those of the corresponding porcelain post insulators The installation dimensions are the same and can be used interchangeably.
