Standard Glass Electrical Insulator

Commodity name： Standard Glass Electrical Insulator

Product Details

Glass insulator ( glass electrical insulator, high voltage glass insulator, glass power line insulators) is a device primarily used in electrical and telecommunication systems to support and separate electrical conductors from their surrounding environment. it is typically made from glass materials that have high resistance to electrical current, allowing them to prevent the flow of electricity between conductors and the structures they are mounted on. the main purpose of a glass suspension insulators is to maintain the integrity and safety of electrical and telecommunication lines. by providing a barrier between the conductors and the structures (such as utility poles or towers),
