NBG Transformers

Nalagarh, Solan, Himachal Pradesh

We manufacture high-performance Generator Transformers designed to step up the voltage generated at power plants for efficient transmission to the grid. Built for heavy-duty applications, our generator transformers ensure high reliability, thermal stability, and long service life under continuous and peak load conditions.
Our transformers are engineered to meet the demanding requirements of thermal, hydro, gas, and renewable power generation plants.

What is a Generator Transformer?A Generator Transformer (GT) is used to step up the generator output voltage (typically 6.6 kV to 21 kV) to higher transmission voltage levels such as 66 kV, 132 kV, 220 kV, or higher for efficient power transmission.

These transformers are designed to withstand:

• High short-circuit stresses
• Continuous full-load operation
• Harmonics and transient conditions
• Frequent load variations

Product RangeWe offer :

• 5 MVA to 200 MVA (or as per requirement)
• Voltage Class up to 220 kV / 400 kV (customizable)
• Oil Immersed Generator Transformers
• ONAN / ONAF / OFAF / OFWF Cooling Types
• With OLTC / Off Circuit Tap Changer
• Custom Designed as per Project Specifications

Manufactured as per relevant IS / IEC standards and utility requirements.

Key Features :

• Designed for Continuous Heavy Duty Operation
• High Mechanical Strength to Withstand Faults
• Low Loss & High Efficiency Design
• Superior Insulation System
