The present invention relates to an insulating spacer for a gas insulated switch gear and a method of manufacturing same. According to the present invention, the insulating spacer comprises: a case (10) having a sealed space filled with an insulation gas; a core conductor (300) which is installed in the case (10) and extends in a longitudinal direction of the case (10); an epoxy molding part (130) installed in the sealed space and supporting the core conductor (300); and an insulating layer (200) formed between the epoxy molding part (120) and the core conductor (300). An outer surface of the core conductor which is in contact with the insulating layer (200) and an outer surface of the epoxy molding part (120) are planar surfaces, and the insulating layer 200 is attached to the outer surface of the core conductor (300) through a coating process. According to the present invention, since the insulating layer made of an epoxy coating layer with high insulation performance is in between the core conductor (300) which constitutes a gas insulated switch gear and the insulating spacer, adhesion between adhered surfaces is increased. In addition, it is not necessary to perform sand blasting on the surface of the core conductor for the purpose of improving adhesion or to round the outer surface of the core conductor (300) to increase an adhesion area. |
