我公司多年來采用優(yōu)質(zhì)材料和的工藝技術(shù)生產(chǎn)150VA到600KVA之間，SG系列三相干式變壓器，是我公司參
照西門子公司同類產(chǎn)品新研制開發(fā)數(shù)控系統(tǒng)用變壓器，尤其150VA-16KVA之間的三相干式變壓器，它們的外形和安裝
尺寸已經(jīng)標(biāo)準(zhǔn)化，與西門子4AP系列通用，產(chǎn)品名VDE0550、IE39、5555、GB226等國際、標(biāo)準(zhǔn)。
         SG系列三相干式變壓器廣泛適用于交流50-60Hz，輸入、輸出電壓不過500V的各種三相供電場合。產(chǎn)品的各種輸
入、輸出電壓的高低、聯(lián)接組別、調(diào)節(jié)抽頭的多少及位置（一般為&plun;5%），繞組容量的分配、次級(jí)單相繞組的配備、整流
電路的運(yùn)用、是否要求帶外殼等，均可根據(jù)用戶的要求進(jìn)行精心的設(shè)計(jì)與制造。ZSG系列三相干式整流變壓器供整流設(shè)備。
整流后作充電、電壓調(diào)節(jié)及直流電源之用。

         SG series three-phase dry - te 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,IE39,555,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 &plun;5%)，distribution of roll group,secondary single-pole roll group.

注：
     1、空格未注尺寸，按用戶要求待定，所列尺寸供參考；輸出電流大于300A的產(chǎn)品為定做產(chǎn)品，產(chǎn)品尺寸會(huì)相應(yīng)改變。
     2、表中所列的額定輸入，輸出電壓根據(jù)需要可以任意組合。
     3、表中所列的電壓和尺寸，可根據(jù)用戶要求協(xié)商確定。

Note:
   1.For the blanks without dmens on,they are waiting for users demands and the listed dimension are only for  referencel;for the special whose
      output current exceed 300A,the product's dimension will be changed corresponding to the current,
   2.The listed rated input & output voltage in the table can be embled freely according to special demands.
   3.The voltage and dimension listed in the table can be ascertained according to theuser's demands.
