Abstract

The invention belongs to a live line work tool of a medium voltage transmission line, in particular to a lead clamp for a medium voltage live circuit which is used for leading out wiring from an overhead conductor when electricity is temporarily used. The lead lamp comprises a hook-shaped conductive seat, wherein the outside of the conductive seat is provided with a connecting terminal for connecting an external lead wire; the inside of the hook part of the conductive seat is provided with an elastic conductive clamp for clamping an overhead bare conductor; the lower end of the conductive seat is provided with a section of screw for connecting an insulating operating lever; the elastic conductive clamp comprises a pair of wafers arranged in a splayed shape; the lower ends of the two wafers are connected with the lower part of the conductive seat, while the upper ends are arranged in two empty slots of the upper part of the conductive seat respectively; spring strips are arranged between the outside of the two wafers and the conductive seat; and the elasticity of the spring strips makes the two wafers be close to each other. The lead clamp effectively solves the problems that electricity is hard to cut off or a live line work vehicle cannot be in place in lapping operation, is convenient for earth potential live line work lapping on the overhead bare conductor, and has high safety.
