U160BP/170 Pollution-Resistant Suspension Glass Insulator
The U160BP-170 anti pollution glass insulator is a pollution-resistant suspension glass insulator designed for overhead transmission lines operating in areas with increased environmental contamination. It is developed to maintain reliable insulation performance in coastal regions, industrial zones, and other locations where salt, dust, or chemical pollutants may accumulate on insulator surfaces.
Based on the 160kN mechanical strength class, the U160BP-170 pollution resistant glass insulator combines mechanical reliability with enhanced environmental adaptability. Compared with standard suspension glass insulators, this model features an anti-pollution design that improves insulation performance under contaminated conditions by providing a longer creepage path.

An anti pollution glass insulator is designed for transmission lines exposed to higher contamination levels. Its structure helps maintain insulation performance when pollutants accumulate on the insulator surface.
The main difference is the application environment. U160BL-170 is a standard suspension glass insulator for normal conditions, while U160BP-170 is designed for polluted environments requiring improved contamination resistance.
They are commonly installed in:
The anti-pollution design helps reduce contamination-related risks, but cleaning requirements depend on local pollution severity, climate conditions, and utility maintenance standards.
Yes. The model is suitable for bulk procurement for transmission projects, EPC contractors, and power equipment distributors.
