Introduction

Products of YDQ series adopt high-quality cold-rolled DQ 151 orientation silicon steel sheet, fold into multi-stage cylindrical frame shaped iron core; on tailor-made high strength insulated tube, high-voltage tower coil is winded with a QZ line directly and continuously. The hull is cylindrical, within which is filled with SF6 gas.

Differences between YDQ (JZ) and YDQ are, ingeniously stack install high-voltage silicon rectifier in high voltage set by inserting and extracting short rod ,which can transform YDQ to power frequency voltage AC output or high voltage DC output.
