Development history of composite suspension insulators

Dec 12, 2018

Composite insulator products are used for insulation and suspension wires in high-voltage and ultra-high voltage AC and DC transmission lines. In the early years, insulators were mostly used for utility poles (low voltage), and slowly developed at the end of high-voltage high-voltage wire connection towers, many disk-shaped or A columnar insulator, which is used to increase the creepage distance. It is usually made of glass, ceramic or silicone rubber. It is called an insulator.
