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.

Types: Long rod composite insulator, tension & suspension insulator, line post, station post/busbar support insulator Composite insulator consists of three parts: Fiberglass core: ECR End fitting: Hot-dip galvanized forged steel and casting steel. Silicone rubber: HTV VOLTAGE RATING & STRENGTH RANGE 11kV up to 500kV. 40kN up to 300kN long rod type, 4kN up to 20kN post type. STANDARD TRONCO ELECTRIC insulators complied with the standard of IEC 61109 & IEC 61952 ADVANTAGES The use of composite insulators in place of traditional porcelain and glass insulators for line insulation has become widespread in the last 20 years. High temperature vulcanized (HTV) silicone rubber is dominating for transmission voltages. Lighter weight Lower cost Easier handling Better resistance to damage from vandals Superior contamination performance APPLICATION Long rod insulators are used for suspension and tension towers for high voltage grids and railway grids. Composite post insulators are used for disconnector, switchgear and substation works. Tronco Electric can also make the design and supply the insulator strings.
Low & High Voltage Silicon Rubber Insulator Long Rod Composite Suspension Insulator Manufacturer Composite Suspension Rod Insulator (Export Type) Installation Instruction: 1. The transportation and installation of the insulator shall be taken good care without any throwing or collision, fiction with various sundries(wires, iron plates and tools etc.) and solid material. 2. When suspending the composite insulator, the knot shall be made on the attachment at the end. Knot on shed or sheath are strictly prohibted. When the rope has to be contacted with shed or sheath, the contacting area shall be packed with soft cloths. 3. Never apply the composite insulator as the assistant tool for the wire distribution and collecttion and collection in case that the insulator can be damages by impact or bending moment. 4. Do not step on the insulator shed with foot. 5. When installing the grading ring, attention shall be attached on the adjustments to make sure that the ring is vertical with the axial of the insulator. And for opening grading ring, the openning directions at both ends shall be consistent to facilitate the discharging and protect the shed. ______________________________________________________________________________ This's Jack from Nengxing Electric Power Equipment (China).
