Glass Core Heating Wire

glass-core-heating-wire-1

Glass core heating wire is manufactured by helically winding a single strand or multiple strands of resistance wire around a fiberglass cord. Any resistance wire from our selection of alloys can be used as the conductor. We stock a variety of sizes and styles of glass cord. Once wound, this heating wire may be used as is or depending on the application, it may require an outer layer of insulation.

Our team of engineers are able to work with you to create a custom design for specific application. See below for more information.
