S7,S9 Power Transformer
This is on energy-saving type of a power transmission & distribution transformer of low loss, voltage regulation without excitation, frequency rating of 50Hz. The device
can be mounted both indoors and outdoors to be connected to power supply mains for a continuous power supply. The transformer is a piece of important equipment in the whole power transmission & distribution system.
Our medium & small size power transformers adopt iron core quality cool-rolled orientational silicon steel scraps whose joints are of a 45ˇădegree angle slope, with copper wire for its winding. There is a ˇŔ5% tap at the high-voltage side winding. The tap is to be connected to a junction switch to exercise unloaded voltage regulation. The device takes a cooling approach of natural cooling in oil immersion.
