U420BP Reliable Electric Pole Glass Insulators Weather Resistance For Heavy Pollution Salt Laden Air

Reliable Anti-Fog Glass Insulators for Heavy Pollution & Salt-Laden Air

Production begins with mineral raw materials, melted at 1500+°C into homogeneous glass. Precision molding shapes the extended-creepage anti-fog profile, followed by annealing to eliminate internal stress.

Glass shells are assembled with corrosion-proof fittings, secured by expanding cement and polymer sealing. 100% inline inspection verifies dimensions, mechanical load, and high-voltage performance under contaminated conditions. Each unit receives traceability coding before protective packaging. This integrated process assures reliable anti-fog performance in coastal, industrial, and high-altitude environments.

In 2004, Huzhou Tailun Insulator Co., Ltd. was established in the Huzhou Economic & Technological Development Zone, on the shore of Taihu Lake in the Yangtze River Delta. Over the past two decades, we have remained fully dedicated to the R&D and manufacturing of premium tempered glass insulators, steadily emerging as a benchmark enterprise in China's glass insulator industry.

Backed by a registered capital of RMB 150 million, total investment of RMB 480 million, and total assets exceeding RMB 500 million, we operate a synergistic dual-base network — the Huzhou Headquarters and Anhui Manufacturing Base — covering a combined area of 118,209 square meters. Our annual production capacity of 10 million pieces, together with a top-three sales ranking for five consecutive years, testifies to both our scale and our market strength.

Our product portfolio comprises six full series: standard, anti-pollution, aerodynamic, ground-wire, double-shed, and triple-shed, with mechanical strength ratings ranging from 40 kN to 550 kN. Engineered for resilience, these insulators perform reliably across a temperature range of -40°C to 80°C, delivering outstanding contamination and weather resistance in demanding environments — from high-altitude plateaus and humid coastal zones to arid desert regions. Covering the entire voltage spectrum from 10 kV to 1100 kV, our solutions are ideally suited for UHV transmission lines, urban grid rehabilitation, and renewable energy projects.

In the domestic market, Tailun serves as a core supplier to both State Grid Corporation of China and China Southern Power Grid. Our products are deployed in over 30 provinces, providing dependable support for landmark national initiatives, including the West-to-East Power Transmission Project. Internationally, we have capitalized on opportunities arising from the Belt and Road Initiative, exporting to more than 20 countries and regions across Southeast Asia, Europe, Middle East and Africa. Our insulators are widely utilized in overseas grid infrastructure, delivering trusted, high-performance solutions to power utilities worldwide.

The company is certified under ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety). We have been recognized as a National High-Tech Enterprise, a Zhejiang Provincial "Specialized and Sophisticated" Enterprise, and one of the Top Ten Brands in China's Power Insulator Industry. With these credentials, Tailun has firmly positioned itself as a key player in the global power equipment sector.
