NOVELTY - The utility model claims a graphene electrode good insulating effect, comprising electrode body, the top part of the electrode body is fixedly connected with a metal cap, the bottom of the electrode main body is fixedly connected with a glass film. cavity of the upper part filling the electrode main body is provided with insulating filler, inner cavity of the electrode body is provided with thread, the outer surface of the electrode body is provided with an insulating sleeve, the insulating sleeve comprises polysulfide rubber, cis-butadiene rubber layers, an insulating film layer, silicon rubber layer and a glass fibre layer, a polysulfide rubber layer on the outer surface of cis-butadiene rubber layer; butadiene rubber layer located on the outer surface of the insulating thin film layer, an insulating film layer on the outer surface of the silicon rubber layer, the outer surface of the silicon rubber layer is located between the glass fibre layer. The utility model matched with each other by insulating filler, polysulfide rubber, cis-butadiene rubber layer, an insulating film layer, silicon rubber layer and a glass fibre layer, solves the problem that the graphene electrode insulating effect is bad, the problem of safety of the electrode.
