Product Structure of Power Frequency Withstand Voltage Test Device

The power frequency withstand voltage test device is suitable for the insulation withstand voltage test of high-voltage electrical equipment, electrical components, insulating materials, etc. It is an essential and important equipment in the high-voltage test.

In this article, GDZX will show the product structure of the power frequency withstand voltage test device.

The power frequency withstand voltage test device has the characteristics of small size, light weight, compact structure, full function, good performance and convenient use, and adopts a single-frame core type iron core structure. The primary winding is wound around the core and the high voltage winding is external. This coaxial arrangement reduces leakage flux and thus increases coupling between the windings. The outer shell of the product is made of a octagonal structure with a better core, and the overall shape is elegant. The external structure is shown in Figure 1, and the internal structure is shown in Figure 2.
