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.
