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.
