Both front section and back section represent as a whole a rectangular structure, having upper edge, lower edge and side edges. Central section connects front section and back section, and forms part of upper surface of insulator. Ribs outgoing from front surface and back surface assist in installation of insulator into specified position. According to other structural version, both front section and back section comprise mount grips, protruding from them and assisting in installation of insulator into specified position. ^ EFFECT: reduced friction of steel rail anchor against concrete sleeper and simplification of installation. ^ 16 cl, 11 dwg |
