LTC Group

What LTC Group does

LTC Group (legally Legnano Teknoelectric Company S.p.A.) is an Italian-headquartered, privately held industrial manufacturer specializing in the production of magnetic cores and laminations for transformers and reactors. Founded in 1983 by the Bertelli family and operating under the direction and coordination of 3B HOLDING S.p.A., the company self-positions as a world market leader in its segment and runs 7 production plants across Italy (4 plants), the UAE (Dubai), and Taiwan, with a stated Asia Pacific manufacturing capacity exceeding 15,000 tons per year and a share capital of EUR 30 million.

The company's core technology is the processing of grain-oriented electrical steel (GOES) - including conventional, high-permeability HIB, and laser-etched low-loss grades - as well as non-grain-oriented electrical steel, into customized magnetic cores used in distribution, power, traction, special, and low-voltage transformers, as well as high-voltage shunt reactors and chokes. It also produces steel clamps in-house for core assembly (certified to EN ISO 3834-2 and UNI-EN 15085-2). Its "LTC Way" lean production model, 65+ years of accumulated production and testing data, and proprietary know-how in laser-etched GOES processing constitute its principal technical differentiation. The company maintains strategic supplier relationships with NLMK Group and thyssenkrupp Electrical Steel (the latter for low-CO2 bluemint(R) steel) and is pursuing a -30% CO2 reduction target by 2030 versus 2021.

LTC Group operates a B2B hardware-sales model, selling custom-quoted magnetic cores and related components directly to transformer manufacturers and end users in renewable energy (wind, solar PV, hydro, cogeneration/biomass), transmission grid operators, railway traction, and special applications such as industrial furnaces, data centers, and instrument transformers. Distribution is handled via direct enterprise sales teams and technical-support departments, with brand-building executed through intensive participation in major international trade shows (CWIEME Berlin, Coiltech, Middle East Energy, ELECRAMA, IEEE PES T&D, Energy Taiwan, TRANSFORM) and selective digital and sponsorship channels. Revenue is not publicly disclosed.

Products and services

• Magnetic Cores and Laminations Fully assembled and pre-stacked high-performance magnetic cores manufactured from grain-oriented electrical steel (conventional, HIB, and Laser grades) and non-grain-oriented electrical steel. Designed for distribution transformers, power transformers, traction transformers, special transformers, low voltage transformers and reactors, and high voltage shunt reactors. Application-specific variants include TSN cores for on-shore wind turbines and TSF cores for off-shore wind (with hot-dip galvanisation or glazing for harsh sea atmospheric conditions), as well as cores for photovoltaic power stations, hydroelectric plants, and cogeneration/biomass plants. Sold directly to transformer manufacturers worldwide.
• Cut Electrical Steel (Longitudinal Slit and Cut Laminations) Processed electrical steel products including longitudinal slit-to-width material and cut laminations supplied to transformer manufacturers for use in transformer construction. Supports the full production cycle from raw materials to finished magnetic cores.
• Steel Clamps In-house produced steel clamps used for magnetic core assembly in transformers. Production is certified according to EN ISO 3834-2 and UNI-EN 15085-2 standards, providing vertical integration that eliminates reliance on third-party suppliers.

Expansion highlights6 records

Direct peers

• Cogent Power (Tata Steel): Cogent Power produces electrical steel laminations and transformer cores for power, distribution and renewables markets globally; its product mix and customer base overlap almost entirely with LTC's core transformers and shunt reactors business.
• Tempel Steel: Tempel Steel manufactures transformer core laminations and electrical steel components for power-transformer OEMs worldwide, serving a similar B2B customer base and competing head-to-head with LTC in cut laminations and stacked core assemblies.
• Spang & Company (Magnetics Division): Spang's Magnetics division designs and manufactures custom magnetic cores, transformer laminations and chokes for industrial and power applications, making it one of the closest pure-play magnetic-core peers to LTC Group.
• Weidmann (Weidmann Holding): Weidmann is a direct peer in transformer insulation systems and engineered transformer components, with extensive overlap in magnetic-core adjacent materials and decades-long relationships with global transformer OEMs — directly comparable to LTC's component-supply model.

Emerging players

• Metglas (Hitachi Metals / Proterial): Metglas manufactures amorphous metal ribbon used in highly efficient transformer cores, representing the next-generation technology competing against conventional and laser-etched GOES cores in efficiency-critical transformer applications.
• Trafotek / Hitachi Energy Transformers: Trafotek (part of Hitachi Energy) is a specialist niche manufacturer of dry-type transformers and reactors with in-house core winding capability, comparable to LTC's product lines in dry-type / LV transformer cores and chokes.

Broad incumbents

• Thyssenkrupp Electrical Steel (tkES): Thyssenkrupp Electrical Steel is a leading producer of grain-oriented electrical steel (GOES), the key raw material LTC processes, and is also an LTC supplier-partner (bluemint®); its potential vertical move into cores makes it a broad incumbent peer.
• POSCO (Electrical Steel): POSCO produces grain-oriented electrical steel, serves Asia-Pacific transformer OEMs with laminations and finished cores, and is the dominant regional incumbent in the same geographies where LTC just expanded via the Taiwan plant.
• Voestalpine (Steel Division): Voestalpine produces grain-oriented electrical steel and is a major European competitor for the upstream GOES supply that feeds LTC's core production, while also supplying laminations into similar transformer OEM customers.
• Hitachi Energy (Transformer Components): Hitachi Energy is one of the largest transformer manufacturers globally and produces cores in-house for traction, HVDC and power transformers — an integrated incumbent competing for the same transformer-OEM wallet LTC addresses.
