The JDX-110 voltage transformer is a fully sealed single-phase four winding oil paper insulation structure, with the body fixed in the oil tank. The upper and lower oil tanks are both circular structures. The porcelain sleeve is fixed on the upper part of the fuel tank with a pressure equalizing ring, and its top is equipped with a stainless steel expander, a primary wiring board, and an oil level indicator. The fuel tank is equipped with a pressure relief valve, and the lower part of the tank is equipped with a secondary outlet box, with an oil sample valve at the bottom.
