High Stability Ground Overhead Line Insulators For Low Voltage Circuits

Ground Glass Insulators are a key component in electrical systems, engineered to insulate and secure conductors in grounding and low-voltage applications. Made from high-performance toughened glass with a specially treated ground surface, it features exceptional resistance to mechanical stress, corrosion, and minor electrical surges, maintaining stable dielectric strength even in outdoor or underground grounding environments. This design ensures consistent and reliable performance in power transmission and distribution networks, particularly in grounding systems, low-voltage circuits, or areas requiring secure conductor insulation for safety and operational stability.​

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.
