INTRODUCTION:
     ZGS9 series combination transformer(also named American box transformer) is different with conventional box transfomer station for fixing the transformer, high voltage load switch and fuse in insulated oil. The contruction is compact.
     The series products have been widely used in resident quarter,public place,enterprise etc.
CHARACTIRISTIC:
*small volume, compact construction,easy for installing.
*entirely sealing,entirely insulatio n construction,safety.
*can be used in whole net,also be used in terminal, easy for transformer, raising the reliability.
*low loss,low noise, perfect performance.
*cable joint adopt insert type which can segregate switch, easy for operating.
*high voltage double fuse protection, insert fuse has double protection of temperature and electrical current.
*reserve fuse protect the transformer from wrong.
+the chest adopt anti-theft construction.
*low temperature raising, strong load ability.
*The voltage quality is good because the transformer using special construction.
