Evaluate this Device
SIRMET ELETTRICA constructs, repairs and modifies MV and LV epoxy resin transformers in the range from 160 KVA up to 10MVA and a maximum operating voltage of 36KV.
The magnetic circuit is made with silicon lamination with low loss oriented crystals with 45 ° weaving in order to minimize the noise level. The core tightening system is sized to withstand the electrodynamic stresses of the windings in the event of a short circuit. The low voltage windings are normally made of aluminum or copper sheet insulated with F or H class materials.
They are protected by H class, high cementation varnish, that once dried in the oven, forms a highly compact mass which is resistant to radial short-circuit stresses to obtain a reduced percentage of additional losses. The axial stresses are very low thanks to the single plate conductor.
