Product Details
Oil-immersed transformer is a new type of high-performance
transformer with more reasonable structure and better performance,
its three-dimensional rolled iron core due to its three core
columns are equilateral triangular three-dimensional arrangement,
there is no air gap in the magnetic circuit, the winding is more
compact, the length of the three magnetic circuits is the same, and
they are all the shortest, and the cross-sectional area of the iron
core core columns is more close to the round shape, so the
performance is further improved, the loss is lowered, the noise is
lowered, and the three balances are made to reduce the third
harmonic component, the product is more suitable for the urban and
rural areas and the transformation of the power grids of the
industrial and mining enterprises, and the product is more suitable
for the combined transformers and the transformers used in
pre-assembled transformers and preloading transformers for
transformer substations.
