What material is suitable for insulating spacer track?
Track polymer composite insulating spacer, characterized in that: the gasket is placed at least two through holes, respectively, is placed around the spacer protrusions prism, the prism arranged between adjacent recesses. This track insulation pads in the track construction tighten the screws only need to complete the construction, convenient, fast, easy to replace gasket also view. Anti-vibration pads, slip resistance, insulation resistance is higher. Set in the track of the spacer plate fasteners and road foundations combination between the fixed, suitable for field construction. Railroad rail end FRP composite insulating spacers, which is installed in the gap between the rail joints, from the electrical insulation.
The spacer is made of glass fiber woven fabric N layers of non-reinforced thermosetting plastics laminate of the N layers of glass fiber mat can also be doped n thin (i.e. non-woven), and the outer layer of the composite layer of the aging The resin protective film. Railroad rails insulated with a high-strength bolts and iron rail insulation epdm gasket ,belonging to the field of railway signaling track circuits rail insulation parts, the insulating gasket is made with epoxy phenolic glass steel rectangle whose area is greater than iron gaskets, peripheral projection, the central groove is formed, iron spacer on the groove to form interlocking relationship. Insulation pads stuck in the fish plate with ribs between two ribs also constitutes interlocking relationships and increase tightening torque.
