0,66kV Single-phase transformers ОСМ, ОСТ, ОСОВ type
Single-phase transformers ОСМ, ОСТ types are applied for power supply of electric drives operation, local lighting, signaling and automation circuits. Windings of all ОСМ, ОСТ and protected transformers on its basis (ОСЗ, ОСОВ type) are made from COPPER wire, and thus the transformers distinctive features are high electric characteristics and small dimentions.
According to customers request, transformers with any possible windings and tappings combinations both as for power, as for voltage.
The transformers in closed performance (ОСОВ, ОСЗ type) and up to 20kVA power may be manufactured.
