(1) The transformer secondary is connected into a triangle shape. It is with low voltage and high current;

(2) The secondary of the transformer is with two or several voltage levels. Selection of the desired secondary voltage and regulation of the power output of the transformer can be realized by changing the high voltage winding wiring;

(3) Structure of transformer is relatively firm. Mechanical strength of winding wiring and insulation strength are strengthened. Cooling condition is relatively good, so the overload capacity will be better and can stand frequent short circuit current impact during melting period. This can avoid coil loose and sharp temperature increase of transformer;

(4) In order to increase the line impedance to a certain extent, and limit the transformer short circuit current to safety value of 2~3 times, the small transformer usually has a reactor. Large and medium-sized transformer shall be used together with independent reactor.
