Yepaungson Transformer Substation is located in Taunggyi district of Myanmar. It is a middle substation in the system and mainly supplies electric power to the nearby cement plant. The substation is equipped with a set of main transformers with the capacity of 60MVA/60MVA/15MVA and is set by three voltage grades separately of 132kV, 33kV and 11kV. The nominal voltage of the transmission line system is 132kV while the highest working voltage is 145kV. The total length of the lines is 0.5km with 5-based iron towers.

Introduction of the project：

A. Yepaungson Transformer Substation: substation capacity of 60MVA. Main electric connection is of single bus connection. The voltage grades are of 132/33/11kV. The equipment of the substation is composed of the indoor and outdoor parts. The indoor part mainly includes the distribution unit of 11kV, control and protection equipment and direct current and communication system equipment. The outdoor equipment covers the 132kV and 33kV outdoor distribution units.

B. 132kV Pyin Nyaung line，output voltage 132kV.Line materials are 132kV transmission line materials of 0.5km，in which 5-based iron towers with the total weight of around 31.8 tons, steel-cored aluminium strand wires of 3300m and the supporting line materials are included.
