Since 1985, Nacional de Transformadores LM has designed, manufactured, and commercialized high-quality electrical transformers, including pole-mounted, pad-mounted, and custom solutions. With decades of experience, we deliver reliable, efficient, and safe products tailored to each project’s needs.
TRANSFORMERS
• Three-phase and single-phase transformers manufactured in accordance
with K0000 standards, with ANCE certification and J Standard compliance.
• Pad-mounted and throat-type transformers for high- and low-voltage
applications.
• Single-phase transformers, conventional and self-protected types, for highand low- voltage systems.
• High-voltage step-down transformers (from 33,000 V to 13,200 V) and lowvoltage step- down transformers (from 440 V to 220/127 V).
• Dry-type transformers.
• Underground transformers (K0000 Standard).
CUSTOM MANUFACTURING
• Dual-voltage transformers for high-voltage applications (13,200 V to
23,000 V or 33,000V, among others).
• Transformers with a fifth bushing for 127 V lighting output.
• Transformers with seven low-voltage bushings, allowing simultaneous
output voltages of 440 V, 220 V, and 127 V.
• Dual-voltage transformers for low-voltage applications (220/440 V or other
custom voltage configurations).
• Additional custom-engineered transformer solutions in specific capacities
(300 kVA, 350kVA, 400 kVA, etc.), designed according to the requirements
of industrial companies and end users.
We commercialize transformers with capacities ranging from 15 kVA
to 1,500 kVA, including pole-mounted, pad-mounted, and custommanufactured transformer solutions.
