NLMK Group is bringing a series of new premium grade transformer steels to the global market.
The new grades of steels are designed for manufacturers of energy-efficient transformers, including those featuring stranded magnetic conductors, that are cost-efficient and easy to manufacture, and are widely used in individual housing construction.
Advanced grades of transformer steel, namely NV23S-100, NV27S-105, NV30S-110 0.23 to 0.30 mm with improved consumer properties can boast 5-10% lower specific magnetic losses vs. commercial grades of electrical steels from other global manufacturers.
The high quality of steel is obtained without laser treating the surface (via the application of barriers). This technology ensures a wider application of stranded conductors where the use of “laser” grades has proved inefficient.
Ilya Guschin, NLMK Group Vice President for Sales, said: “NLMK Group is one of the global leaders in the production of such advanced steel products as transformer steel. In 2016, the group held 9% of the global transformer steel market. We are constantly working on developing our transformer steel production technologies to boost our clients’ competitive edge.”
Transformer (GO, anisotropic) steel is used in the electrical industry to produce transformer cores and fixed parts of electrical machines.
More than 98% of transformer steel produced by NLMK Group companies is prime quality grade with superior magnetic characteristics, including 23%, which is ultra premium grade with particularly low specific losses.
Currently NLMK produces 8 premium steel grades in gauges from 0.23 mm to 0.30 mm: NV23S-095L, NV23S-100L, NV27S-100L, NV27S-105L, NV30S-110L, NV23S-100, NV27S-105, and NV30S-110. (NLMK/Ukrainian metal)
