High Voltage Glass Insulators for Reliable Power Transmission

Product Overview

Glass insulators are widely used in high-voltage transmission and distribution systems to ensure reliable insulation and mechanical support for overhead power lines. Manufactured from toughened borosilicate glass, these insulators offer excellent electrical performance, long service life, and superior resistance to weathering and environmental stress.

At Wei Shoe Electric, our glass insulators are engineered to meet international standards for quality, mechanical strength, and electrical safety, making them a trusted choice for global power utilities and infrastructure projects.

Case Study: Wind Farm Transmission Project in Spain

In 2022, Wei Shoe Electric supplied over 12,000 units of 160kN glass suspension insulators for a 220kV wind farm grid connection project in northern Spain. Despite operating in a coastal environment with high humidity and salt exposure, the insulators maintained excellent performance without flashover incidents for over 18 months of continuous operation.
