Main functions and features of S13 power transformers
●S13 power transformers have low losses. According to the current international GB/T20052-2020 "Technical Parameters and Requirements for Three-Phase Oil-Immersed Power Transformers", the capacity of 30-1600kVA, the no-load loss of the S13 series of power transformers has dropped by an average of about 50%, and the load loss has dropped by an average of about 30%;
●S13 power transformers have low no-load current. Due to the excellent material of the wound core and the characteristics of the winding process, the no-load current is significantly reduced. According to the current national standard GB/T20052-2020, the no-load current of the S13 power transformer series has dropped by an average of about 75%;
●S13 power transformers have low operating noise. According to the B/T10088-1999 noise standard, the noise of the S13 series is reduced by about 7-9dB.

●S13 power transformer has strong short-circuit resistance. The transformer body is in the shape of a three-dimensional triangular prism. Pull screws are set all around and form an integral body with the upper and lower iron yoke insulation and laminated wood blocks. It can effectively resist the axial and radial mechanical stresses during sudden short circuits.
