Does Giga Energy make reliable transformers?

Our transformers are engineered to the highest standards and backed by a one-year warranty. We have thousands of units operating successfully across diverse applications, from Fortune 500 AI and hypercompute data centers to municipal utilities to solar and wind renewables projects, as well as mining. Our quality control and engineering processes have earned the trust of industry leaders like Microsoft, NVIDIA, and major utilities nationwide.

What is your quality control process?

Our quality control system combines rigorous standards with hands-on oversight. While all our manufacturing facilities maintain ISO 9001 certification, we go much further by stationing our own full-time quality technicians working daily at our factories. These Giga personnel implement a comprehensive inspection process covering component verification, assembly checks, and final testing to ensure every transformer meets our high standards.

What certifications do you have?

Our three-phase and single-phase padmount transformers are UL-Listed and meet applicable NEMA, ANSI, IEEE, and DOE standards.

Where are your transformers built?

Our Los Angeles, California facility serves as our main hub of operations. This facility houses our inventory and primary maintenance capabilities. We have a global supply chain, which provides us with the flexibility and speed required to source components and create the fastest lead times possible. Everywhere Giga operates, we have a substantial boots-on-the-ground presence. Our technical team, headquartered at multiple locations across the United States, works directly with our manufacturing technicians to ensure quality and consistency.

Are you the manufacturer?

Yes, Giga is the manufacturer. We build transformers through our own factories and strategic manufacturing partnerships, all under Giga’s direct control. Our engineering team designs every transformer and maintains a continuous hands-on presence during the manufacturing process. Giga engineers work directly on the factory floor, overseeing production and maintaining our rigorous quality standards.
