The utility model discloses a 10KV lightning arrester test rack. A vertical-type insulation separator plate is installed on a triangle support. An upper wire connection terminal is horizontally fixed on the upper portion of the plate surface of the insulation separator plate. A grounding wire connection terminal longer than the upper wire connection terminal from the left side is fixed horizontally on the lower portion of the plate surface of the insulation separator plate. Left falling-type and right falling-type wire connection terminals are installed in an upper-lower corresponding mode on the both sides of a ground wire seat and the upper connection terminal. The left end of the grounding wire connection terminal is provided with fixed-type lightning arrester mounting base. A grounding leading wire is installed between the mounting base and a fixing screw of the support.
