The QYGTB series of dry-type high-voltage test transformers are made of advanced insulating materials and high-quality magnetic alloy materials, epoxy vacuum casting and a new process of CD-type iron core. Compared with similar products of oil-immersed transformers, it has the characteristics of moisture-proof, dust-resistant, flame-retardant, low loss, and low noise. It has improved insulation strength and can withstand short-circuit surge current without damaging the equipment. The product is small in size, light in weight, beautiful in appearance, stable in performance, and convenient to carry for field operation and test. It is a new type of AC and DC dual-purpose high-voltage test transformer currently updated in China. The product has been tested by the National High Voltage Measuring Station Center, and its performance meets the requirements of the ZBK41006-89 standard.
