Chinese OEM Rail Insulator/Railway Liner/Railroad Insulator for Railway Fastener

ail insulator is an essential part for railway fastening. It is installed between rail clip and steel rail, with the function of adjusting rail gauge and electrically insulating rail rail and concrete tie or sleeper.

The rail insulators are made of nylon 6 or Nylon 66 with glass filler content 20% to 35%, with high performance on usage life and mechanical purpose.
