The triangle mandrel and the tip are processed by one piece,
and made of steel plated with hard chrome
Angle of mandrel: 3*R0.5mm±0.02mm
Angle of tip: R0.5mm±0.02mm
Working method: the mandrel is rotated by hand
Balance block: 1N ±0.1N* 2, made of stainless steel
Weight: 150N±10N*1 (for downward force)
Test method
The metal foil and mandrel should be rotated slowly and
without jerks at 2300 from initial position to final position for 3 times
-from the initial position to the final position and back
-as above for the second time
-from the initial position to the final position
Accessory: Metal foil has 500mm long, 70mm width and 0.035
mm±0.005 mm thickness
Mandrel Test Equipment is designed according to IEC61588 figure 6, IEC60950 annex A, IEC60065 figure 14 to 17 and GB1921. It is used for the insulating thin layer of the power transformer and supply unit as well as the similar products to do the mandrel test, mechanical strength test and abrasion test.
This test device will have a mechanical limit in the position of 10o and 230o to make sure the accuracy of the testing angle. Thus, the operation method is simpler. The weights are with suspension loop to prevent the sample from damage due to the large stress. Mandrel Test device should work with withstand voltage tester.
