Composite Suspension Long Rod Insulators

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.

Long rod composite insulators are mainly used in high voltage overhead power transmission & distribution lines for insulation and mechanical connection. Normal operation conditions: 1 Ambient temperature: -50c-+50c 2 Altitude: not more than 3000m 3 Frequency: not more than 100hz.

Composite Insulator Design: 1) GB/T19519-2004; IEC; ANSI 2) KEMA certification, ISO 9001 3) 10~1000kV / 70~600KN 4) Material: composite Polymer 5) Self-refined silicone rubber with imported raw material from DOR CORNING CO. USA; Fumed silica is imported from CABOT CO. in the USA and WACKER CO. in Germany. 6) Weathershed: silicon-rubber sheds are the feature of TAIGUANG technology. 7) Made of ECR core, acid and high temperature resistance. 8) Metal end fittings: advanced compressing technique with Acoustic Emission Detector imported from Finland. Performance: 1) Excellent electrical insulation properties and restoration of insulator performance 2) High mechanical strength 3) Good features of light weight, self cleaning, easy to install, anti-aging. 4) Good resistance to soiling and flashover 5) Hydrophobicity of sheds meets class HC1 .

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).
