Wound-Cut Type C Cores for High Temperature Transformers

An inorganic binder was developed whereby woundcut type C cores can now operate at higher ambient temperatures. The inorganic binder, having the composition and properties of glass, served as an electrical insulator as well as the adhesive. Grain-oriented silicon steel was used in the construction of sample cores for the evaluation of the developed inorganic glassy binder over a wide temperature range.
