GB/T 4074.8-2009Winding wires - Test methods - Part 8: Test procedure for the determination of the temperature index of enamelled winding wires - Quick-Test method (English PDF)

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.
