Railway insulator, there are commonly two kinds of railway insulator: composite railway insulator and porcelain railway insulator.The composite railway insulator has smaller size, lighter weight than porcelain insulator. Moreover, the composite railway insulator has good internal and external insulation capabilities, high mechanical strength.
The composite insulator can be used without regular cleaning, but the porcelain railway insulator should be cleaned regularly.
Railway insulator is mainly for high-speed rail and urban rail transit construction.
