AC power frequency withstand voltage test transformer

1、 Product Overview

AC power frequency withstand voltage test transformerThe iron core is a single frame type. The coil adopts a multi-layer tower structure with the same core cylinder. The primary low-voltage winding is wound on the iron core, and the secondary high-voltage winding is wound on the outside of the low-voltage winding. This coaxial arrangement reduces the coupling loss between the windings. The high-voltage silicon stack is packaged in a sleeve using a process, and the outer shell of the product is made into an octagonal structure that matches the core, resulting in an overall beautiful and elegant appearance.It has the characteristics of small size, light weight, compact structure, complete functions, and easy use. It is a practical instrument used in power, industrial and mining, scientific research and other departments to conduct power frequency withstand voltage tests and DC leakage tests on various high-voltage electrical equipment, electrical components, and edge materials. It is the * instrument in high-voltage testing.
