天津市电机厂1982～1987年间,在消化吸收引进技术的基础上,陆续试制完成了1215～1228系列新型潜水电机,实现了6、8、10和12英寸低压潜水电机的改型换代,并于1987年12月上旬通过了鉴定。1215～1228系列潜水电机设计先进,并采用了一系列新工艺、新材料,力能指标比较高,其效率 From 1982 to 1987, based on the digestion and absorption of imported technologies, the Tianjin Electric Machinery Factory successively completed the series of new submersible motors of the 1215-1228 series, realizing the retrofit of 6, 8, 10, and 12-inch low-voltage submersible motors. The appraisal was passed in early December 1987. The 1215~1228 series submersible motors are advanced in design, and adopt a series of new technologies and new materials. Their performance indicators are relatively high and their efficiency is high.
