沈阳市第四变压器厂

沈阳市第四变压器厂（有限公司）始建于 1961 年，是原机械工业部定点生产油田专用变压器、电脱盐防爆变压器及原油脱盐、脱水、精制电源成套设备的专业厂家。

我厂于1989 年开发国内首套原油电脱盐设备在长岭炼油厂一次试验成功，实现了我国电脱盐设备制造的零突破。

凭借先进的设备、专业的技术团队，以及荣获国家级奖项的 TYDK/TYDKZ/JBDKZ 系列变压器，我厂产品广泛应用于电网、炼油厂、海上平台及石化行业，并出口至多个国家。

远超设计年限的电脱盐变压器

2025年，我们收到乌鲁木齐石化的询单，发过来的设备我们一看是我们94年生产的产品，居然已经使用了31年，远超我们的设计年限（10年）。当我们的看到那斑驳的铭牌时，很多人和事都不在了，但老企业的精神让我自豪，四变厂生产的产品经受住了考验。企业在，魂就在。

Beyond Design Lifespan

In 2025, we received an inquiry from Urumqi Petrochemical about equipment we manufactured in 1994. It had been operating reliably for 31 years—over three times its 10-year design life—proving the durability of our transformers.
