EPRO Gallspach - Model Type IR -Toroidal Cores for Transformer Bushing
Epro specializes in manufacturing toroidal cores, specifically the Type IR, which are primarily used in transformer bushings or switchgears under oil or SF6. The company offers a range of standards and precision classes to meet diverse requirements. These toroidal cores can be produced with two types of outer coverings: a white polyester tape or Hostaphan foil, which provides 3kV insulation when used without an intermediate layer in transformer bushings. Epro accommodates a variety of customer-specific options, such as color-coded connections, stray field compensation windings, and paper insulation. The Type IR cores are available in various sizes up to approximately 800mm in diameter, supporting configurations as single-core CTs or as multi-core CTs with up to six cores. The maximum weight of these cores is around 400kg, making them versatile for different industrial applications.
This is the most common execution. The use is to shunt on the transformer bushing or in switchgears under oil or SF6. Epro offers all kinds of standards and accuracy classes. There are two possibilities of outer bandage, the one with white polyester tape the other with „hostaphan“ foil for 3kV insulation when there is no intermediate layer when mounting in the transformer bushing. Hardly all customer desired options are possible to realize like color code for the connections, compensation winding for stray field or paper insulation etc.
Epro is producing the type IR in all sizes up to approx. 800mm as single core CT or together as multi core CT up to 6 cores. Weight limit is approximately 400kg.
