Product overview

This product has the performance of low no-load loss, low no-load current and low noise.ltimproves the quality of voltageand the reliability of power supply, and is a green energy-saving equipment that is beneficial to the environment.

The company produces s13-mrl, s11-mrl,series ofully sealed three-dimensional three-phase coil core transformerdfferent from the traditionalplanar laminated core transformer. The iron core is composed ofthree- phase column railarrangedin three- dimensional triangle.Each cylinder is made of high quality cold rail ilicon copper thin strip continuous winding, thebandwidth is made straight line or curve shear by numerical controlmaterialcuttr, the belt materialis wound in the core coilerto form a nearly circular or flanged circular arc plate and then processed by vacuum nitrogen illing annealing to eliminate processing stress, character reorientation, improve magnetic permeability, improve electromagnetic performance; The high andlow pressure coil is directly wound on the paper sheet of the core pillar with a special winding machine. The overall structure issolid and compact.The upper and lower rail insulation and laminate wood are adopted for the body.

Product features

According to the current international GB/t6451-2015three-phase oil-immersed power transformer technicalparametersand requirements, capacity 30-1600KVa,S13-mrlseries no-load loss decreases 50% on average, and load loss decreases30% on average, s11-mrl series no-load loss decreases 30% on average, and load loss decreases 25% on average.

Low no-load current

According to the current national standard GB/t6451-2015, the no-load current of s13-mrlseries decreases by 75% on average, and the no-load current of s11-mrlseries decreases by 75% on average.

Low operating noise

According to the noise standard of JB/t10088-2008, the noise of S13~MRL and S11-MRL series were reduced by about79dB.

Strong short circuit resistance

The transformer body is in the shape of three-dimensional prism, and the tension screw is set around and in the center,which is integrated with the insulation and laminated wood of the upper and lower rails, and can effectivel resist the axialandradial mechanical stress in case of sudden short circuit.
