Protected by heat-resistant insulation, this wire is often used in ovens, furnaces, and other electrical heating equipment.

Wire with a fiberglass outer and mica inner insulation is also known as MG wire. It’s often used to wire equipment in steel mills, iron mills, and glass manufacturing.

Wire with a fiberglass outer and PTFE inner insulation is also known as TGGT wire. It resists chemicals and moisture and can be used in industrial drying equipment.

High-Temperature Cable

The insulation on this cable withstands high-heat applications such as ovens and furnaces. The wires are silver or nickel plated for corrosion resistance.

Use unshielded cable in applications where signal interference is not a concern. It has a layer of fiberglass fabric and mica tape around each wire. The entire cable is wrapped in a layer of fiberglass fabric and mica tape, and then covered in PTFE. The PTFE outer insulation resists chemicals, oil, abrasion, and moisture.

Thermocouple Wire

Solid Thermocouple Wire

Stranded Thermocouple Wire

Make your own thermocouples.

Stranded wire is more flexible than solid wire.

Fiberglass insulation and jacket is rated for higher temperatures than FEP and is highly chemical resistant.
