CRGO STEEL LAMINATION
CRGO steel is imported in the form of mother coils from reputed steel produces in Russia, USA, Japan, Korea, Germany, China etc. Each coil confirms to the specification of Bureau of Indian standards of quality (IS3024).
Nu-Cork manufactures cut-to-size laminations for Power & Distribution transformers and CT/PTs depending on customer design and guaranteed losses. We process lamination up to 132 Kv class. We have sufficient installed capacity to cater the market of specified ranges.
CNC Cut-to-Length machines are able to process lamination in various shapes and sizes. We process vertical step lap and horizontal step lap as per customer specification from 3/5/7/9/11 steps. CRGO lamination necessitates a high level of precision, which is why we execute severe quality checks on a regular basis, measuring burr level, camber, waviness; stack height, weight, and other metrics.
BUILT-UP TRANSFORMERS CORE
Nu-Cork has different sizes and types of stacking tables in order to produce complete flat stacked lamination. The cores are built on modern core stacking tables. Stacking on guiding bolts and most accurate setting of the leg supports on centre distance enables to keep the geometrical dimension to an absolute minimization of the air gaps. We built transformer core from 16 KVA to 10 MVA rating. A pre-measurement of the core losses guarantees the required No Load Losses measured on a digital power analyzer.
