Introduction


Transformer, GIS, SF6 switch, CT/PT, insulator, bus bar, cable, bushing, and others capacitive devices are the common primary electric equipment. Composed by power control cabinet, excitation transformer, reactor, voltage divider, connects silicon rectifier stack and micro ammeter with the voltage divider, then can finish the DC voltage withstand test.

Features


1.It with smaller volume, lighter weight compared with others reactors which in same voltage class and capacity. With small temperature rise under rated load; strong mechanical strength, good insulation performance, reliable.
2.The capacity of the power control cabinet is high; strong protection function; good output waveform; good stability; multi-function, easy to operate; single phase 220V or three phase 380V are available. 
3.Can match different kinds reactors, multifunctional, highly cost effective.
