  2. Self-regulating heater - Wikipedia

    en.wikipedia.org/wiki/Self-regulating_heater

    A positive-temperature-coefficient heating element (PTC heating element), or self-regulating heater, is an electrical resistance heater whose resistance increases significantly with temperature. The name self-regulating heater comes from the tendency of such heating elements to maintain a constant temperature when supplied by a given voltage.

  3. Kanthal (alloy) - Wikipedia

    en.wikipedia.org/wiki/Kanthal_(alloy)

    For heating, resistance wire must be stable in air when hot. Kanthal FeCrAl alloy forms a protective layer of aluminium oxide (). [1]Aluminium oxide has high thermal conductivity but is an electrical insulator, so special techniques may be required to make good electrical connections.

  4. Resistance wire - Wikipedia

    en.wikipedia.org/wiki/Resistance_wire

    Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures, up to 1,400 °C (2,550 °F). When used as a heating element, resistance wire is usually wound into coils.

  5. Heating element - Wikipedia

    en.wikipedia.org/wiki/Heating_element

    In a suspended design, a resistance heater is attached at two or more points to normally either a ceramic or mica insulator. Suspended resistance heaters can transfer heat via convection and radiation, but not conduction as they are surrounded by air. In an embedded heating element, the resistance heater is encased in the insulator.

  6. Insulation system - Wikipedia

    en.wikipedia.org/wiki/Insulation_system

    The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.

  7. Thermal conductance and resistance - Wikipedia

    en.wikipedia.org/wiki/Thermal_conductance_and...

    The SI unit of absolute thermal resistance is kelvins per watt (K/W) or the equivalent degrees Celsius per watt (°C/W) – the two are the same since the intervals are equal: ΔT = 1 K = 1 °C. The thermal resistance of materials is of great interest to electronic engineers because most electrical components generate heat and need to be cooled.
