TEK Transformatör is a privately held Turkish manufacturer of power and distribution transformers, founded in 1982 and headquartered in Ankara. The company operates from a 42,000 m² production facility with 200+ skilled professionals and an annual production capacity of up to 7,000 transformers, with maximum ratings of 31.5 MVA and 66 kV. Its product portfolio spans dry-type cast resin transformers, power grid step-down distribution transformers (25-3150 kVA), step-up transformers for renewable energy applications, wind turbine transformers (100kVA-10MVA), solar power plant transformers (250kVA-10MVA), BESS transformers (250kVA-10MVA), grounding/isolation/substation special transformers, pad-mounted and pole-mounted CSP transformers (including Smart CSP variants with IoT/SCADA integration), and medium power transformers.

The business operates a B2B enterprise hardware sales model with quote-based pricing, supplemented by ISO/IEC 17025-accredited testing and inspection services. Go-to-market is executed through direct field sales teams and regional offices in Chicago (USA) and Dubai (UAE), plus active participation in international energy trade shows (FISE 2025, RE+ Las Vegas, Solar & Storage Live UK). The customer base is concentrated among national and regional utilities and renewable energy developers, with named government customers including TEDAŞ (Turkey), SONABEL (Burkina Faso), SOMELEC (Mauritania), and SENEL, and enterprise customers including SPIE. The company holds ISO 9001, 14001, 45001, 27001, 17025, 26000, and 37001 certifications, serves 50+ countries, and has delivered more than 7,000 MVA of cumulative transformer capacity. Its export ranking among Turkish electrical and electronics exporters rose from 84th in 2022 to 52nd in 2024.

Revenue is not publicly disclosed. Revenue mechanics are driven by custom-engineered transformer hardware sales plus ancillary testing services, with bottom-of-funnel conversion typically occurring through long-cycle utility and project tenders rather than transactional e-commerce.
