1. Product Introduction:

The S13 series three-dimensional coil iron core transformer has a three-dimensional triangular shape as a whole, with tension screws set around and in the center, which are integrated with the upper and lower iron yokes insulation and laminated wooden blocks. The high and low voltage coils are perfectly circular and concentric wound, which can effectively resist axial and radial mechanical stress during sudden short circuits and have strong short-circuit resistance.

The iron core is made of cold-rolled silicon steel sheets, which have good stability, low noise, and low no-load loss. The coils are produced using high-quality electromagnetic wires, resulting in low load loss.

The current implementation standards for three-dimensional iron core transformers include "Technical Parameters and Requirements for Three phase Oil immersed Three dimensional Iron core Distribution Transformers" and "Energy Efficiency Limits and Grades for Three phase Distribution Transformers".

2. Product features:

Low loss: According to the current international GB/T6451-1999 "Technical Parameters and Requirements for Three phase Oil immersed Power Transformers", the capacity is 30-1600kVA, and the average no-load loss of S13-M.RL series is reduced by 50%, and the average load loss is reduced by 30%;

Low no-load current: Due to the excellent material of the wound iron core and the characteristics of winding processing, the no-load current is significantly reduced. According to the JB/T10088-1999 noise standard, the noise of the S13-M.RL series is reduced by about 7-9 dB.

Strong short-circuit resistance: The transformer body is in the shape of a three-dimensional triangular prism, with tension screws set around and in the center, which are integrated with the insulation of the upper and lower iron yokes and laminated wooden blocks, effectively resisting axial and radial mechanical stress during sudden short circuits.
