We manufacture a wide range of high voltage electricity railway insulator, and we always offer A high performance of high voltage electrical insulators because we have almost 20 years design, manufacturing and exporting experience.
1.Technical data of railway insulator
Rated mechanical bending load
Min nominal creepage distance
1min power frequency wet withstand voltage (kV)
Full wave lightning impulse withstand voltage peak value (kV)
1).Light weight (65-80% less than ceramic insulator).
2).High mechanical strength.
3).Silicon rubber sheds provide perfect hydrophobic performance.
4).Excellent water detesting, endurable to dirty.
5).It is not so easy to be damaged in the course of transporting and installing.
6).The insulating umbrella design outside is rational, improve the wet lightning to press effectively.
1).The top comprehensive research and development manufacturing ability.
2).Almost 20 years experience with insulators, surge arresters and fuse cutouts.
3).ISO9001 and ISO14001 and third party support and assurance from Europe.
4).All of our products are tested and qualified by National Inspection Institute and IEC/ANSI standard.
5).Design test + Type test + Sampling test +Routine Test for products.
