Transformer TM-400/10/0.4 and TM-400/6/0.4 Overview

TM-400/10/0.4 and TM-400/6/0.4 transformers are high quality oil-filled three-phase transformers designed for efficient power conversion in industrial and commercial applications. These models have a robust design intended for operation in moderate climatic conditions, with the ability to operate in 6 or 10 kV (or up to 35 kV) networks complying with Russian GOST standards.

Construction and materials

Transformers TM-400 have a robust metal housing with reinforced construction for protection against external influences. The oil transformer includes an expansion tank with an air dryer to prevent moisture and contamination. The oil tank is also equipped with an oil level compensation system to compensate for temperature fluctuations.

Compliance with GOST
