Abstract
This high-voltage fuse comprises a tubular housing and a fuse subassembly within the housing with a core in the form of an elongated, cylindrical body primarily of silica sand particles bound together in a rigid, porous mass, a fusible element wound about the core, and connector assemblies at opposite ends of the core electrically connected to opposite ends of the fusible element. The fuse subassembly is closely surrounded by silica sand in the space between the housing and the subassembly.

A high-voltage fuse subassembly comprising:
- (a) a core in the form of an elongated body primarily of silica sand particles bound together in a porous rigid mass having an outer peripheral surface,
- (b) a fusible element wound about said core after said sand particles are bound together in said porous rigid mass, said fusible element contacting said outer peripheral surface, and
- (c) connector assemblies at opposite ends of said core electrically connected to opposite ends of said fusible element.
