Transformers also have the characteristics of small size, light weight, compact structure, complete functions, strong universality, and easy use, making them an essential and important equipment in high-voltage testing

1. According to the principle of "distance effect" in transformer oil, multi-level insulation is adopted to divide the internal insulation of the transformer into multiple oil channels, thereby improving the insulation level and reducing the volume.
2. Solved the oil leakage problem of TDM series transformers. Since TDM series transformers do not have oil reservoirs, when the temperature is too high, the oil expands and leaks out from the oil nozzle. However, this series of products sets the oil injection hole at the top of the sleeve, and the oil in the sleeve is connected to the oil in the body of the transformer. So, in addition to its functions of installing silicon stacks, short-circuit rods, and series excitation rods, this sleeve also serves as a transformer oil reservoir.
3. This series of products uses metal fixed leads and voltage equalization to eliminate discharge phenomena.
4. The stain box has a compact structure, novel appearance, small volume, and light weight.
