INSULATING FISHPLATE Russian patent published in 2008 - IPC E01B11/04 

FIELD: railway transport; permanent ways.

SUBSTANCE: invention is designed for use in insulated joints. Proposed insulating fishplate is made of polymeric material and contains at least one current-conducting embedded member along fishplate. At least one of longitudinal support surfaces of fishplate at least at one end out of zone of rail joint contains current-conducting section being part of embedded member. Fishplate is made in form of shaping skeleton whose longitudinal walls are interconnected by vertical cross partitions. Invention is aimed at designing of nonexpensive insulating fishplate featuring high strength characteristics and making it possible to decrease magnetization of rails at butt joint to level below value sufficient for attraction of metal dust, i.e. to form shunting bridges in insulated joint.

EFFECT: improved quality of insulated butt joint.
