ABSTRACT:
A pressure- and weather-resistant fuse tube having fiberglass reinforcement which cannot interfere with arc-extinguishment and which does not require an insert or liner of arc-extinguishing material. The fuse tube is molded from a thermosetting material which includes an effective amount of an arc-extinguishing material. The fuse tube includes an inner bore-defining portion and an outer weather-resistant portion which are simultaneously molded along an interface at which is located a layer of porous fiberglass cloth, or filament. The fiberglass is sufficiently porous to permit the material of both portions to pass through and thoroughly impregnate it, thereby locking both portions to each other and to the fiberglass which is located well away from the bore thereof.
