JDCF-220(W2) High Voltage Voltage TransformerDetailed product description：

The JDCF-220 voltage transformer is a fully sealed series oil paper insulated single-phase four winding structure. The primary winding is divided into four groups, which are respectively mounted on the upper and lower columns of two frame type iron cores. The body of the winding is fixed on the base and immersed in the oil of the high-voltage porcelain box. The upper part of the porcelain box is equipped with an expander; The N terminal of the primary winding, the secondary winding, and the residual voltage winding are led out by a small porcelain sleeve on the base, which is equipped with an oil sample valve.
