TOROIDAL CUT CORES AND “C” CORES - FeSi
Electroterni produces cut cores of all shapes and sizes according to customer requirements.


Cores are available in standard sizes (HWR-FA-SU-SM-SE-S3U-HWE and LOW PROFILE) or based on customer specification.

Cut surfaces are ground to customer requirements.

The production of these kinds of cores requires the setup of special tools.

Products are available in the following thickness range:

FeSi: 0.05 – 0.10 – 0.15 – 0.18 – 0.23 – 0.27 – 0.30 – 0.35 mm

FeNi: 0.10 – 0.20 mm

Electric performances depend on core type and magnetic length; guarantees are defined upon order confirmation.


DELIVERY STATE

Wound cores are manufactured with conventional and high-permeability grain-oriented silicon steel sheet and/or super grain-oriented steel. Filling factor is 95 %.

The cores manufactured with grain-oriented silicon steel of 0.10 mm in thickness weigh approx. 3% less than those of 0.30 mm.
