High-voltage test transformers are necessary test equipment for power equipment testing and preventive tests. With the development of my country's power industry, the requirements for the voltage level of test transformers are getting higher and higher, and oil-insulated test transformers are increasingly unable to meet the requirements of on-site work in terms of volume and weight. With the progress of basic scientific research in our country, the application of new materials and new processes has pushed the new insulating medium sulfur hexafluoride gas (SF6) to the application field of power equipment. Due to the good insulation performance and arc extinguishing performance of sulfur hexafluoride gas, and non-combustibility, it can be widely used as a new insulating medium in power systems.

After years of hard work, our factory has successfully researched a gas-filled ultra-light test transformer. Compared with oil-immersed test transformers, this product is small in size, light in weight, free of oil pollution, not affected by climate change, and has minimal corona, etc. Advantages, the voltage of a single unit can reach 300KV.

1. The gas-filled test transformer is small in size and light in weight (40%-65% lighter than the oil-immersed test transformer of the same grade

2. Clean, no oil, no maintenance

3. It is not affected by the harsh weather environment, and the test can be done without standing still when transporting on site

4. The insulation strength is significantly higher than that of the oil-immersed test transformer, and the corona is extremely small
