According to data available, hundreds of main transformers have been upgraded and thousands of kilometers of transmission lines rearranged across the country, thereby opening up prospects of increasing voltage class of the electric-power distribution system within several months.

Power distribution stations in all provinces are bringing about good results in upgrading main transformers and hastening the rearrangement of transmission lines, while solving technical problems arising in cities and counties in close contact with relevant units.

Insulator producing units are producing and supplying in time insulators necessary for increasing voltage class of the electric-power distribution system.
