The invention relates to a high-voltage fuse comprising a tubular ceramic insulating member that is provided with at least one fusible element, an inner auxiliary cap which is placed on the insulating member and at least partly covers the outer surface of the insulating member in the front area of the insulating member, and an outer top cap that is placed on the auxiliary cap and at least partly covers the outer surface of the auxiliary cap. The insulating member is provided with at least one depression. The auxiliary cap is molded against the insulating member such that a positive connection to the insulating member is created in the depression. The auxiliary cap and the top cap are molded in the area of said depression in such a way that a positive connection is created. In order to create a high-voltage fuse which ensures that the insulating member is covered so as to be tight towards the outside even at elevated temperatures, a sealing means is provided in the depression while the top cap and/or the auxiliary cap are molded against the sealing means in said depression.
High-voltage fuse, with a tubular ceramic insulating member having at least one fusible element, with an inner auxiliary cap which is placed on the insulating member and at least partially covers the outer surface of the insulating member in the front area of the insulating member, and with an outer top cap which is placed on the auxiliary cap and at least partially covers the outer surface of the auxiliary cap, wherein the insulating member has at least one depression, wherein the auxiliary cap is molded against the insulating member such that a positive connection is formed with the insulating member in the depression, and wherein the auxiliary cap and the top cap are molded in the area of the same depression such that a positive connection is formed, wherein a sealing component is provided in the same depression and that the top cap and/or the auxiliary cap is molded against the sealing component in the same depression.
