About Trafo CZ
Trafo CZ, a.s. manufactures TRAFOCZ oil-immersed distribution transformers and offers low-loss transformers for photovoltaic and wind plants. Its services include repair of oil distribution transformers up to 2,500 kVA, oil sampling and analysis, high-voltage testing, transformer rental and buy-back, and refurbished units. The company also sells dry distribution transformers, which its website says it sources rather than manufactures, and is an authorised distributor of Nynas transformer oils in the Czech Republic since 2013.
Customers include energy utilities, industrial and service organisations, and investors and operators of solar and wind plants. The company is a contract partner of the ČEZ Group for supplies of new transformers and repairs. Revenue comes from transformer sales, repair and maintenance services, rental, and oil distribution.
The registry lists the company's founding as 27 December 2006, with its registered seat at Koutníkova 208/12 in Plotiště nad Labem, Hradec Králové. Its website states that TRAFOCZ transformers have been supplied since 1992 and that the company continues the production and service tradition of VČE - transformátory, s.r.o. The registry lists an employee band of 50–99. The careers page gives only a contact address and phone number and does not list specific open positions.
Product: TRAFOCZ oil distribution transformers, low-loss PV transformers, transformer repair, rental, refurbished units, and Nynas transformer oil distribution.
