Composite Post Insulator series are used for power station facilities. The products have good hydrophobicity, anti-aging, anti-leakage and anti-corrosion, high torsion strength and anti-bending strength, high mechanical strength, anti-impact performance, anti-shock and anti-brittle fracture performance, high anti-fouling ability, superior impact resistance, small size, light weight, easy installation. Its top and step mounting dimensions are the same as the corresponding porcelain pillar mounting dimensions. Maintenance-free, without manual cleaning, and it can be used interchangeably with porcelain insulators.
