我公司多年来采用优质材料和*的工艺技术*生产150VA到600KVA之间，SG系列三相干式变压器，是我公司参
照西门子公司同类产品*新研制开发数控系统用变压器，尤其150VA-16KVA之间的三相干式变压器，它们的外形和安装
尺寸已经标准化，与西门子4AP系列通用，产品*名VDE0550、IE*39、*5555、GB226等国际、*标准。
SG系列三相干式变压器广泛适用于交流50-60Hz，输入、输出电压不*过500V的各种三相供电场合。产品的各种输
入、输出电压的高低、联接组别、调节抽头的多少及位置（一般为&plu*n;5%），绕组容量的分配、次级单相绕组的配备、整流
电路的运用、是否要求带外壳等，均可根据用户的要求进行精心的设计与制造。ZSG系列三相干式整流变压器供整流设备。
整流后作充电、电压调节及直流电源之用。

SG series three-phase dry - t*e transformer is suitable for all kinds of three-phase power supplycircuits with AC50-60Hz,input and
output voltage up to 500V,Especially for transformer with 150VA-16KVA,their shape and installing dimension are standar dized and can be
used together withSiemens4AD series.SG series confirm to VDE0550,IE*39,*555,GB226 and other international and national standard.
According to used demands,we can design and produce products with dirrferent input & output voltage,coupling group,quantity and position of
adjusting tab(usually &plu*n;5%)，distribution of roll group,secondary single-pole roll group.
