Standard Transformer
Suzhou Huadian professionally developed 3~500kV/√3, 0.2~0.005 level environmental protection and energy saving dry-type precision voltage transformer. The iron core adopts imported high-quality high-performance iron core, the cross section is circular, the window is rectangular, and the magnetic circuit is completely closed. There is no magnetic leakage, and the magnetic performance is optimal. It has high precision, small error, good annual stability, small size and light weight. The coil is made of imported environmentally friendly epoxy resin vacuum casting, with good insulation performance and high withstand voltage (the primary winding withstand voltage is 1.5Un). It is easy to carry, no maintenance, suitable for vehicle and field use, and can also be used for laboratory calibration.
