ABSTRACT:
An enclosed insulator assembly has a generally cylindrical polysiloxane body, a tubular Durethan® core with upper and lower terminals, Multilam™ contacts within the terminals, an arc-quenching tube, and a manually removable handle. Entrance holes in the body accommodate the coupling of external cables to the terminals. A threaded cylinder positioned on the handle's interior accommodates one of an interchangeable cutout fuse tube assembly and disconnect tube assembly and permits the assembly to be inserted into the core as the handle is positioned on the body. Both assemblies have top and bottom fittings with O-rings that prevent weather corrosion between the fittings and terminals. A grooved load interrupter is attached to the bottom fitting of the assemblies to suppress arcing when the assembly is pulled out from the body.
