Mandrel Tester Device 

1. Introduction

Mandrel tester device is designed and manufactured in accordance with the standard requirements of IEC61558 and IEC60065. It is used for the insulating thin layer of the power transformer and supply unit as well as the similar products to do the spindle 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.

2. Technical parameters

1) Mandrel: nickel plating triangle mandrel

2) Weights: 150N*1（the weight of farmar ring is included）

3) The tension of the two terminals of material foil: 1N

4) The rotating angle of the mandrel: 230 o

5) The height of the bottom of the mandrel: 500mm
