Features

• According to the current international standard GB/T6451-1999 “Technical Parameters and Requirements of Three-phase Oil-immersed Power Transformers”, the average no-load loss of S13-MRL series is reduced by 50%, and the average load loss is reduced by 30% for capacities between 30 to 1600kVA. For S11-MRI series, the average no-load loss is reduced by 30%, and the average load loss is reduced by 25%.
• Low no-load current
• due to the excellent quality of the roll core material and the winding processing characteristics, the no-load current is significantly reduced. According to the current national standard GB/T6451-1999, the average no-load current of S13-MRL series is reduced by 75% and the average no-load current of S11-MRL series is also reduced by 75%.
• Low operating noise
• According to JB/T10088-1999 noise standards, the noise of S13-MRL and S11-MRL series is reduced by about 79dB.
• Strong resistance to short circuit
• The transformer body has an overall three-sided prism shape and screw bolts are set up around the four sides and in the center. The top and bottom iron rails are insulated and laminated with wooden blocks, which effectively resist the axial and radial mechanical stresses during sudden faults or short circuits.
