Technosvar Ltd. offers TVK 75 transformers.
Single-phase transformers TVK-75 UHL4 and TVK-75-04 are designed for powering the resistance welding machines.
Climatic modifications of TVK-75 include UHL4 and 04. Nominal climatic factors of TVK-75 comply with GOST 15150-69 and GOST 15543-70, except for the cooling water temperature, maximum and minimum values of which are set respectively to +25°C and +1°C, and the maximum ambient air temperature for TVK-75-04 transformers, which is set to +40°C. The environment - non-explosive, not containing dust in the amounts which cause unacceptable deterioration of the transformer parameters.
