Steel aluminium complex insulation support for condact rail

The utility model discloses a steel aluminium complex insulation support for condact rail, comprising a base plate, one side fixedly connected with second connecting plate of bottom plate, the one endthat the second connecting plate was kept away from to the fourth connecting plate has the connecting block through third bolt threaded connection, the one end sliding connection that the second connecting plate was kept away from to the third connecting plate has the compound condact rail of steel aluminium, the utility model relates to an insulation support technical field. This steel aluminiumcomplex insulation support for condact rail, solved in electrically conductive process because the friction can produce a large amount of heats, can lead to the inside production deformation of condact rail, because deformation goes round and begins again, can lead to fixed insulation support breaking occur, simultaneously because the one end that current support is used for the stationary contact rail is a whole apron, t
