New JSHP 50/66 MVA 69 kV GRDY / 34.5 kV Step-Up Power Transformer

This available transformer is a new three-phase step-up power transformer manufactured by JSHP Transformer Co., Ltd. with a nominal rating of 50/66 MVA and designed for 60 Hz service. The unit is configured 69 kV GRDY / 39.837 kV HV to 34.5 kV LV with ONAN/ONAF cooling and mineral oil insulation fluid. The nameplate identifies vector group YNd1 and notes the unit is suitable for step-up operation. 

Based on the provided technical description, the transformer is offered in New condition and described as unused and stored by the manufacturer. The supplied documentation indicates application suitability for utility-scale, industrial, and power distribution service where immediate availability may offer an advantage over new-build lead times. 

The nameplate also shows an on-load tap changer, copper windings, ANSI design reference, and BIL values for the HV, LV, and neutral bushings/windings. Shipping and total weight information are provided in both the technical description and nameplate package, supporting logistics planning for transport and installation.
