Development History of High-voltage Composite Insulators
- May 25, 2018 -

Composite insulators began internationally in the 1950s and have been in existence for more than 40 years. Silicone rubber composite insulators began production in the world around 1967. China's silicone rubber insulators began production in the world around 1967. The history of production and operation of silicone rubber insulators in China has been more than ten years. Thousands of domestic high-voltage composite insulators are in operation in power systems. With the implementation of UHV power transmission projects in China, the project of further transmission of power from west to east is proceeding. The demand for high voltage composite insulators will increase significantly.
