Product Overview
  • S(B)H21-NX2 (Energy Efficiency Level 2): This 10kV oil-immersed amorphous alloy transformer is built with the upgraded "NX2" design, tailored for industrial power distribution scenarios. Its core adopts a wound structure that eliminates joint loss, and when combined with a vacuum oil-filling process, it delivers a marked improvement in insulation performance—critical for stable operation in harsh industrial environments.
  • The cooling system has been revamped into a hybrid setup of oil-immersed self-cooling and forced oil circulation, enabling the transformer to handle prolonged high-load conditions without overheating. As a Level 2 energy-efficient unit, it cuts comprehensive losses by 35% compared to the S(B)H15 series, directly lowering long-term energy costs for enterprises with non-stop production.
  • It is ideally suited for power distribution in continuous-operation industries like steel and chemicals. Moreover, the transformer is equipped with a pressure relief valve and gas relay, which boost fault response speed by 50% and reduce the risk of extended production disruptions.
