Strip Wound Cores
■Strip wound cores for transformers and chokes
▲Iskra, d. d. is one of the major Slovenian producers of various types of strip wound transformer cores made of oriented silicon iron steel strip. With the production line and highly trained personnel, Iskra fulfills the requirements of local and foreign markets.
▲To produce high-quality cores for transformer and chokes, Iskra uses an oriented silicon iron steel strip that contains 3% silicon. We mainly produce cores from M103-27P and M089-27N materials. The strip thickness is 0.27 mm and can be used up to 200 Hz. The grain oriented silicon iron steel strip Trafoperm N2 with thickness 0.1 mm cover the frequency range from 200 Hz to 2 kHz.
▲For the production of cores, Iskra selects the GOESS suppliers and ensure diligent control of production and the quality of the entire working process. All cores are measured 100% by a computer controlled measurement system MDK1000A. The test reports are available for customers in PDF form.
