The railway insulator is an insulator product suitable for electrified railway tunnels with complex operating conditions. It is installed between steel rail and tie plate, for adjusting rail gauge and electrically insulating railroad rails, rail clips and rail bolts from the interior of a concrete sleeper. It can effectively prevent pollution flashover accidents and reduce the workload of cleaning and maintenance. Due to its small size, especially when the tunnel clearance is small, it is irreplaceable for ceramic insulator and glass insulators. Why insulated Rails are main parts of the rail tracks. They lead the train and transfer the pressure of the wheels to the sleepers. It must have a continuous smooth surface with minimum resistance. Currently in the electrified railways or automatic block zone the two rails double as signal lines of track circuits and loop line for locomotive traction. So rails must be insulated in case of stray current interference. Usually insulators and insulated rail joints are used in rail tracks. What are the types of railway insulators The following is the classification method of railway insulators: 1. Classification by structure Insulators are divided into: column (post) insulators, suspension insulators, pin insulators, butterfly insulators, tension insulators, anti-fouling insulators and bushing insulators. In addition, the cross arm can be regarded as a generalized insulator. 2. According to different functions It is divided into ordinary insulators and anti-fouling insulators. With years of experience designing and manufacturing railway insulators, has developed a new concept to improve safety and performance while optimizing cost considerations for our customers. is willing to cooperate with colleagues from all over the world and customers in the wider power field.
35kV--500kV outdoor solid core post insulators are used in outdoor power stations, substations, distribution installation and electrical equipment for insulating and supporting. The insulators are suitable for use in ambient temperature from -40fª to 40 fª, partial products are used at an altitude up to 4000 meters. The insulators are divided into normal type and anti-pollution type .Anti-pollution type insulators are suitable for used in medium and heavy polluted areas. The insulators are of solid core construction which possesses advantages of long service life, ensured service safety and minimum maintenance work. In order to guarantee the mechanical property of the insulators, each porcelain piece is checked the internal fault by a ultra-sonic detect or so as to eliminate unqualified product . The insulators can be manufactured, tested in accordance with IEC60168 and IEC60273. Other standards such as ANSI, DIN and BS are also available.
