    About Wire and Cable
    industrial info icon

    Compare wire vs. cable and choose the right option based on gauge, number of conductors, insulation, and current rating.

    High-Temperature Lead Wire

    Image of Product. Front orientation. Lead Wire. High-Temperature Lead Wire.
    Even at 480° F—hotter than some industrial ovens—this wire’s insulation won’t melt.
    Stranded Wire with Fiberglass Fabric Outer Jacket and Mica Inner Insulation—Wire with a fiberglass outer and mica inner insulation is the common choice for steel mills, iron mills, and glass manufacturing. You may know it as MG wire.
    Stranded Wire with Fiberglass Fabric Outer Jacket and PTFE Inner Insulation—Wire with a fiberglass outer and PTFE inner insulation won’t corrode from moisture, so it’s often used in industrial drying equipment. It also won’t become brittle or crack from chemicals. This wire is commonly known as TGGT wire.
    Silicone-Coated Fiberglass Fabric Outer Jacket—Wire with a silicone-coated outer insulation shields your skin from fiberglass particles when handling the wire.

    High-Temperature Thin-Insulation Lead Wire

    Image of Product. Side1 orientation. Lead Wire. High-Temperature Thin-Insulation Lead Wire.
    With a slim PFA plastic insulation, this wire has the same heat resistance as standard high-temperature wire but its diameter is one-third the size for use in tight spaces. It withstands water, sunlight, and chemicals, making it good for use in oil and gas applications. It’s also known as hook-up wire.

    High-Temperature Power Cable

    Image of Product. Front orientation. Power Cable. High-Temperature Power Cable, Unshielded.

    Unshielded

    When others can't take the heat, this cable delivers power in ovens, furnaces, steel mills, and foundries. The PTFE jacket won't degrade and weaken as temperatures rise. It also resists abrasion, chemicals, oil, and moisture.
    Fiberglass Fabric over PTFE and Mica Tape—A layer of mica tape, naturally heat resistant and electrically insulating, delivers superior protection against high temperatures.
