Special cores

Magnitosila specializes in the production of magnetic cores not only of standard configurations for power three-phase transformers. The scope of our capabilities includes the manufacture of almost any charge specialized magnetic cores.

Our reference list includes:

  • single-phase and three-phase magnetic cores for induction furnaces;
  • magnetic cores for arcing reactors;
  • magnetic cores for regulatory systems;
  • magnetic cores of quenching plants;
  • magnetic circuits for water-cooled inductors
  • and many others.

Experienced designers and engineers of our plant are ready to adapt the customer’s documentation to modern materials and technologies, as well as to develop a magnetic circuit design in the complete absence of design data (from a living sample or according to the technical task).

New equipment: Slitting line

Continuous improvement is one of the main goals of the company “Magnitola”. That is why we strive to expand the machine park, as well as upgrade existing equipment. We present a new slitting line for electrical steel (both transformer and dynamic). Launched in may 2020, the line allows us to get consistently high quality and significantly reduce the time of cutting strips for further processing.

Hardware features:

  • Cutting of electrical steel up to 0.5 mm thick (including NV30-120, NV30-130, T 111-30s, T 130-30S, M400, etc.)
  • Initial roll width up to 1250 mm
  • Weight of the initial roll up to 5 tons
  • edge Burr, no more than 20 microns
  • roll width deviation no more than 0.1 mm

We are glad to provide to our partners not only services for the manufacture of magnetic cores, but also with a separate longitudinal cutting of electrical anisotropic and isotropic steel into strips.

Power Grids 2019, Moscow

Traditionally, in early December, the Magnitosila team took part in the Power Grids forum.

The forum has established itself as a leading platform for communication between representatives of federal and regional authorities, heads of major network and generation companies, equipment manufacturers, scientific organizations and associations, Russian and foreign experts to discuss pressing issues of converting priority energy infrastructure through the introduction of digital technologies and platform solutions.

In 2019, IFES business events were honored by 386 industry experts and 17,888 participants. The exhibition was attended by 405 exhibitors from 31 countries – manufacturers of high-tech equipment, domestic and foreign developers, innovative companies and startups.

Magnitosila, presented its products, and also held a series of negotiations with potential customers!

Magnetic cores laminations using STEP-LAP technology

STEP-LAP technology in the manufacture of magnetic cores can significantly reduce no load losses in the finished product (compared to a combined joint). This is especially true in the production of power and distribution transformers with capacities above 160 kVA.

The capabilities of our production allow us to produce and ship individual sheets of magnetic cores to the customer. The need for separate sheets is relevant if the customer has his own section for assembling magnetic cores. At the same time, the site must have specialized equipment, equipment and qualified personnel

The transverse cutting of electrical steel for magnetic cores according to the “step-lap” technology is a set of magnetic circuit plates laid in bags on pallets. Steel grade, plate geometry (see the section on technical production capabilities), step-lap parameters, requirements for stacking packages and fixing plates on pallets can be made in accordance with customer requirements.

Assembled magnetic cores

We offer the manufacture and supply of magnetic cores for power transformers and complete reactors.
“Assembled” – means that, in accordance with the design documentation, sheets of the magnetic circuit, insulating parts, metal structures of the core will be manufactured, as well as batching and assembly.

Our own hoisting mechanisms and internal workshop transport allow us to produce fully assembled core cores weighing up to 6 tons.
