Composite insulators have been widely used in the Electrical power industry and railway electrification all over the world, and their qualities have a great influence on the safe operation of transmission lines and railway contact systems. Therefore, strictly controlling product qualities, improving the structure of products, and lengthening their serving lives has turned out to be the main issue for the composite insulator industry. The production method for composite insulators are injection, compression and sleep-on shed. Our technical department will suggest the best production method for the customers after considering the voltage, qty, and production capacity. The polymer insulators have passed the inspection of China National Labs.
