Winding wires test methods
Part 8. Determination of the temperature index of enamelled winding wires
Test Method for Rapid method
1 Scope
This section GB/T 4074 specifies the test weight measured by enamelled round wire thermostat life and life in the dynamic thermal hot atmospheric air
And a temperature index approach to changes in the electrical strength as the failure criterion, the test results can be assessed as a selection of electrical equipment insulation paint
Wire wrapped round basis.
Scope.
--- Determination of enamelled round wire (including self-adhesive enameled round wire and enamelled round wire) and temperature of thermal life index, the study of two or more
Compatibility of composite wire;
--- Determination of different metal conductors and conductive surface treated by different enamelled round wire lifetime and temperature index.
When the results of this section measured reasonable objection shall GB/T 4074.7-2009 routine tests to conventional law prevail.
