Glass insulators are insulating components that naturally emerged with the development of telecommunications and power transmission lines. They were first used in telegraph lines in the mid-19th century, and subsequently expanded to telephone, power distribution, and high-voltage transmission systems. Their development progressed from hand-blown glass insulators to mass production using molds, and then to tempered glass insulators. Currently, glass insulators hold a significant market share in high-voltage transmission and railway sectors, and traces of their use can still be found in everyday life.
Countries such as the United States, Canada, France, Malaysia, and Brazil still have a significant demand for glass insulators. China is currently the largest exporter of glass insulators, and its annual production volume ranks among the world’s top. The quality of Chinese glass products is absolutely guaranteed.Furthermore, the prices offered by Chinese suppliers are quite low, providing excellent value for money. Discounts are also available for large purchases.
These are the prices for some of our best-selling glass insulators. Our minimum order quantity is 1000 pieces. If you purchase in bulk, our prices are negotiable.
