Good bending resistance performance, strong anti-fouling ability and impact resistance, vibration and anti-brittle fracture performance, small volume, light weight, convenient installation, free maintenance.
With high hydrophobicity as well as strong resistance to aging, tracking, and erosion, the composite post insulator is usually applied in the power stations. It has high tensile strength and flexural strength. It is also impact resistant. Quake proof, and anti brittle fracture. In addition, this lightweight product is easy to install.Its top and bottom mounting dimensions are the same with those of the porcelain type pin insulator, so they can be used interchangeably.
