State Grid
Insulators are essential components of the power grid that electrically separate live conductors from supporting structures and the ground while carrying mechanical loads. Made from porcelain, glass, or polymer/composite materials, they prevent leakage and flashover under voltage stress and harsh environmental conditions, ensuring safe, reliable transmission and distribution of electricity.
Railway Lines
Railway insulators electrically separate energized components (overhead catenary wires, pantographs, or third rails) from supporting structures while also withstanding mechanical loads. They prevent current leakage and stray-return currents that can damage track infrastructure or interfere with signaling, and they protect maintenance staff and the public; common types include suspension/post insulators, insulator brackets/spacers, and insulated rail joints made from porcelain, glass, or polymer composites.
Substation
In substations, insulators electrically isolate live conductors and high-voltage equipment (busbars, switchgear, transformers) from grounded structures while bearing mechanical loads. They prevent arcing and flashovers, maintain required creepage distances under pollution, and ensure safe, reliable operation of protection devices and personnel safety.
