TMG 630-1600 kV

TMG 630-1600 three-winding transformers are power oil-filled three-phase three-winding hermetically sealed transformers with a capacity from 630 to 1600 kV∙A and voltage up to 10 kV. They provide reliable and efficient power conversion, stable operation for consumers, and optimization of network losses. Designed for use in urban, industrial, and rural power systems, these transformers are manufactured according to modern technical requirements and quality standards, allowing them to withstand significant loads under long-term operation. They are used in electrical installations for solar and wind energy.

Design Features

TMG transformers have a modern three-winding design, allowing operation with multiple voltage levels. This provides flexibility in power supply schemes and increases system efficiency.

Design solutions:

• Hermetically sealed oil-filled tank — a completely closed casing excludes contact of transformer oil with air, which significantly reduces the risk of oxidation and the need for maintenance;
• Three windings — allow using the transformer in multi-stage power systems, providing greater functionality;
• Welded metal tank structure — gives the transformer high strength and resistance to mechanical stress;
• Natural oil cooling system (ONAN) — ensures efficient heat dissipation without the need for additional cooling devices;
• Control and measuring elements — built-in devices for monitoring winding temperature, oil level, and other parameters guarantee safe and stable operation.

Advantages of Using TMG Transformers

Using TMG transformers significantly increases the efficiency of the power system, reduces operating costs, and ensures stable power supply.

Main advantages include:

• High energy efficiency due to low losses in no-load and short-circuit modes;
• Reliable design that withstands long-term operation even in challenging conditions;
• Simple technical maintenance — the hermetically sealed tank does not require regular oil changes;
• Long service life — over 25 years under normal operating conditions;
• Low noise level, allowing installation within residential areas;
