Amorphous

Driven by government legislation, electrical utilities and transformer manufacturers are now looking for innovative ways to increase transformer efficiencies.

Compared with conventional transformer cores, amorphous metal distribution transformer cores (AMDTs) can achieve a reduction of approximately 70% in no-load loss.

Metglas™ amorphous metal, is only 0.001” thick and is therefore used predominantly in distributed gap, wound core applications, in transformers where an ultra low no- load loss is required. […]

Distributed Gap Wound Cores

Distributed gap wound cores – also known as DG Cores – are popular in the distribution transformer industry, especially in single phase units where transformer no-load losses close to the intrinsic loss of the steel are possible.

They offer excellent performance with the added benefit of a very simple champing structure and assembly process, often utilizing 75% fewer components than an equivalent stacked core. Therefore, the time taken to assemble a core is dramatically reduced. […]

Special Products

Cogent produces and supplies a range of special components for the North American and global transformer industry. Typically produced parts are identified in the list below. Cogent works closely with clients in all applications requiring electrical steels and magnetic materials for unique and customized applications.

Magnetic steel and tank liners (shield) for large power transformers that are custom-made to individual design requirements. These shields reduce tank stray losses and eliminate tank hot spots by introducing a relatively high permeability shunt path that carries stray flux. […]
