24kV Polymer Pin Post Insulator

24kV Polymer Pin Post Insulator is applied to high voltage power line service.

And have features of good hydrophobicity, anti-ageing, anti-leakage trace and electric erode proof, tensile strength and bending strength, strong mechanical strength, shock resistance good quakeproof and brittle failure proof, light weight, easy to installation, and the installation size of top and base are the same size with porcelain pin type, they can exchange to use each other.

Products Advantage

1.Products meet international standards

2.High mechanical strength, impact resistance, shock and crisp resistance

3.Easy installation and long service life

4.Quality and quantity guarantee
