Ceramic Bushing Insulators Excellent electrical insulation High
compressive strength alumina bushing
Small Glazed Bushings
For passing a conductor through a low-voltage conducting panel
When passing a conductor through a conducting panel at low
voltages, steatite ceramic bushing insulators are required.
Small Glazed Bushings
Alone or in pairs, they provide an economical method of supporting
wires, rods or grids in ovens, power cabinets, and other
applications.
Male pieces may be used alone in some cases. In pairs, a machine
screw is used to hold the bushing halves together. A range of
standard sizes is available for most needs. Clear glaze is
standard.
Special bushings in almost any size or shape can be manufactured to
your specifications. Isolantite has extensive experience with the
design and production of specialty bushings.
