TFE - Abbreviation for tetrafluoroethylene.
TFF - Same as TF, except stranded copper conductor.
TG - PTFE tape with overall glass braid, stranded nickel-clad copper conductor.
TGGT - Flexible stranded nickel-coated copper conductor with PTFE tapes, covered by wrapped fiberglass yarns. A fiberglass braid jacket is applied over insulation and is treated with high-temp saturant. 600 volt, 250° C rating.
THERMAL RATING - The maximum and/or minimum temperature at which a material will perform its function without undue degradation.
THERMAL RESISTANCE - The resistance of a substance to conductivity of heat.
THERMAL SHOCK - A test to determine the ability of a material to withstand heat and cold by subjecting it to rapid and wide changes in temperature.
THERMOCOUPLE - A union of dissimilar metals in which a voltage is generated due to a change in temperature. The voltage is usually in micro or milli volts.
THERMOCOUPLE EXTENSION - Same as thermocouple lead wire.
THERMOCOUPLE LEAD WIRE - An insulated pair of wires used from the couple to a junction box or to the recording instrument.
THERMOCOUPLE WIRE - Wire drawn from special metals or alloys and calibrated to established specifications such as for the U.S. Bureau of Standards or Instruments Society of American standards.
THERMOPLASTIC - A material which softens when heated and becomes firm on cooling.
