What Hansen Electric does

Hansen Electric, spol. s r.o. is a Czech privately-held electrical equipment manufacturer headquartered in Opava, with origins in explosion-proof device production dating back to 1958 and the company formally established in 1992. The company operates two divisions: an explosion-proof electrical equipment division producing transformer sets (up to 3150kVA), switching and load centers, HR-VS vacuum contactors (80–630A, up to 1200V), LED lighting fixtures, junction boxes, and the APD1 intrinsically safe conveyor control system — all certified to ATEX and IECEx for use in underground mining hazardous atmospheres; and an electric motors and generators service division providing repair, refurbishment, and rewinding of LV/HV AC and DC motors, hydrogenerators up to 20 MW and 12 kV, and transformers, supported by in-house diagnostics (vibration analysis, dynamic balancing up to 5000kg, laser alignment, thermovision, and withstand voltage testing up to 15 kV). The company also produces new three-phase asynchronous mining motors (HVM 250 M4 and HV(K)M 280 M4).

The business generates revenue through three streams: sale of explosion-proof electrical equipment (hardware sales), new electric motor production, and professional services including motor and generator repair, diagnostics, and on-site servicing. Pricing is custom quotation-based and not publicly disclosed. The go-to-market is enterprise field sales with engineering-led engagement, supported by wholly-owned subsidiaries in Poland, Russia, Ukraine, Turkey, and Singapore, plus representation in Mexico, Kazakhstan, Belarus, Vietnam, South Korea, and South Africa. Distribution is direct to underground mining operators (OKD, SUEK-Kuzbass, Raspadskaya, DTEK, ArcelorMittal Temirtau, VINACOMIN, Minera del Norte), power generation facilities (multiple hydroelectric plants in Czechia, Sweden, and North Macedonia), nuclear operators (ČEZ nuclear division, qualified supplier since 2022), and OEM mining equipment manufacturers (EICKHOFF, KAMAT, BREUER-MOTOREN, SIEMENS).

The company holds ISO 9001, ISO 14001 (2017), ISO 3834-2 (2020), ATEX (2001), and IECEx certifications, and is authorized by the District Mining Authority in Ostrava for installation, operation, and consulting on gas-mine electrical equipment. It became fully independent through a management buyout in 2013 and currently operates 101-250 employees across its Czech facilities and international subsidiaries.
