Custom Three Phase Transformers
Three-phase power transformers are ideal for power distribution and electrical systems requiring efficient distribution and high-power transmission capabilities. At higher power ratings, three-phase transformers are less expensive, lighter, and more flexible than other power transformer configurations.

Three Phase Transformer Advantages
Three-phase transformers are widely used in electrical power systems for their efficiency, reliability, and versatility. They are designed to handle three-phase power, the most common method of transmission and distribution. Custom three phase transformer benefits include:
- Compact designs take up less space
- Economically converts AC to DC power
- Lighter weight construction
- Ability to accommodate three-phase and small single-phase loads
- Multiple single-phase toroidal transformers or ferroresonant devices can be integrated into three-phase power systems
- More economically efficient
- Easier to operate than three single phase transformers

VA Ratings
GTC typically works with power ratings ranging from 500VA to 20kVA, including custom power transformer sizes up to 200kVA.
Input/Output Voltage, Input/Output Current, and Load Requirements
Our custom transformers generally feature 120V to 600V capacities. However, we can build lower than 120V to meet your requested specifications. Our UL insulation system limit is 600V, and our current max is 200A.
Frequency Ratings
We can build transformers at 50, 60, and 400Hz. We do not manufacture high-frequency transformers or high-voltage transformers.
Power Transformer Size
Our custom power transformers range from small surface-mount control transformers to larger ones. We can meet your specifications with power capabilities from 50VA to 200kVA transformers.
