Specific Inspection Items For Electrical Fittings Before Leaving The Factory (i)

1.Insulation Piercing Connector Corrosion test: a test to test the corrosion resistance of components under certain temperature and salinity conditions.

2. Impact dynamic load test: a test to apply instantaneous mechanical dynamic load to components under specified conditions to simulate the load-bearing capacity of components under accident conditions.

3. Zinc layer uniformity test: a test to check the uniformity of the coating by replacing metal ions.

4. Corona test: a glow discharge test in an electric field with high field strength near the conductor.

5. Partial discharge starting voltage test: a test to measure the minimum voltage when partial discharge occurs on the surface of the conductor.

6. Radio interference test: a test to measure the radio interference level of the test piece under the operating voltage.

7. Thermal stability test: a test to determine the thermal stability of the temperature and loss of the test piece under specified overload conditions.

8. Low voltage and high current test: a test conducted when the voltage of the test piece is a small percentage of the rated value and the current is the rated value or greater than the rated value.

9. Aging test: A test in which a specified aging factor is applied to the specimen, thereby evaluating the service life in a time much shorter than the actual service life.
