YDQ series are essential equipment during electrical equipment tests and preventive tests. With the development of China's power industry, people required higher about the voltage class of testing transformer, and the traditional oil / dry type test transformer cannot meet the requirement in volume, weight, and functions.
With the development of Chinese basic scientific research, the appliance of new material and new workmanship, the new medium SF6 enter the electrical equipment applications. The SF6 widely used because of its excellent insulating properties and arc performance and incombustible.
SF6 test transformer compared with the traditional oil / dry type test transformer, 20%-60% reduction in weight (depend on the voltage and capacity class), without oil pollution, voltage class can up to 300KV. It is especially suitable for condition of working or moving frequently.
