Amorphous Metal Core Oil-immersed Transformer

Amorphous Metal Core Oil-immersed Transformer

With the development of amorphous metal in the 1970s, it became widely used in 1990 as a high-energy-saving material for the transformer industry. Currently, over 1 million tonnes of amorphous metal-type transformers have been connected to the grid worldwide. The longest proven safe and most reliable transformer has been running for more than 30 years, and it still performs satisfactorily in the power industry.

The energy saving is huge and it shall be the new era products in the power industry.

Amorphous Metal Replacing Silicone Steel

Amorphous metal is a metallic material with a disordered atomic-scale structure.

Amorphous metal is non-crystalline, the alloys of boron, silicon, phosphorus, and other glassformers with magnetic metals (iron, cobalt, nickel) are magnetic, with low coercivity and high electrical resistance. The high resistance leads to low losses by eddy currents when subjected to alternating magnetic fields, a property useful e.g. transformer magnetic cores.

Feature of Amorphous Core: Three phases three columns, self-invention by CEEG, which received many patents, low iron loss, temperature rise and noise level, transformer dimension small.

1) All raw materials are supplied by Hitachi Metals with iron loss of less than 70-80% of the standard silicon steel.

2) The company has special treatment, procedure, and manufacturer processes, which have patent numbers: 200810238258.6,20082015857.5，200820215858.X, 200820215812.8, 200820215814.7.

3) The core structure is clean and strong, which is not influenced by the movement created during transportation.

4) The three-column structure can withstand high-level harmonics. At Y-connection, the transformer can resist the 3rd harmonic in the network.
