As my country’s power industry continues to develop, there is an increasing demand for higher voltage ratings and lower partial discharge levels in test transformers. Traditional oil-immersed test transformers, however, are becoming increasingly inadequate for on-site testing requirements due to their size, weight, and partial discharge characteristics.\u003cbr\u003e With the application of new materials and processes, SF6 gas—valued for its excellent insulating and arc-extinguishing properties—has gained widespread use as a modern insulating medium.\u003cbr\u003e Through years of dedicated research and development, our company has successfully created the SF6 series of test transformers. Compared to traditional oil-immersed units, these transformers are 20% to 60% lighter (depending on voltage and capacity ratings), eliminate oil-related contamination, and achieve partial discharge levels of ≤5pC. A single unit can reach voltage ratings as high as 1200 kV. By utilizing low-voltage reactor compensation technology, the current on the 380V power supply side is reduced by 60%, offering significant convenience for users during testing. This series is particularly well-suited for use by provincial and municipal power supply companies, large industrial and mining enterprises, research institutes, and universities.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0955\/0967\/6315\/files\/10-100wj001.jpg?v=1792547451\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003eProduct Features:\u003cbr\u003e1.
