Product Introduction

       Test Transformer, also known as a Step-up Transformer, is an essential device for dielectric strength testing of power generation and supply equipment, various electrical products, and insulating tool materials.

        Our company's Dry-type Test Transformer series has completely transformed the outdated condition of old test transformers being bulky, large, and heavy. When equipped with our matching high-voltage silicon stacks, it can provide a DC high-voltage test power supply. Paired with control boxes (consoles), automatic protection microammeters, sphere gaps, and other auxiliary equipment, it is particularly suitable for on-site testing, making heavy work convenient, fast, flexible, and significantly improving efficiency. Therefore, it is highly welcomed by high-voltage testing personnel in power systems and large industrial plants.

Product Features

        This product series adopts entirely new design concepts, material selections, and process flows, ensuring reduced volume and weight without compromising performance.

        Utilizing advanced production equipment, the series employs coil winding epoxy vacuum casting and high-quality cold-rolled silicon steel CD-type cores, effectively minimizing leakage flux. For DC withstand voltage tests, no external silicon stack is required; simply install our matching DC high-voltage silicon stack onto the high-voltage terminal to obtain DC output.
