U100B glass insulator has excellent electrical performance and mechanical strength. Its high insulation performance can effectively prevent current leakage, strong weather resistance, and is not easily affected by temperature changes and ultraviolet radiation. It can maintain stable insulation effect even after long-term use. In addition, the glass insulator has smooth surface, is not easy to accumulate dirt, and has good self-cleaning property, which reduces the maintenance demand. At the same time, it has a long service life and high anti-aging capability, and is suitable for the harsh environment of high-voltage transmission lines.Product Description
