Frequently Asked Questions

What is a "Pad-Mounted" transformer?

It is a self-contained unit housed in a tamper-resistant steel cabinet, designed for outdoor ground-level installation in residential areas.

Does it meet US utility standards?

Yes, all GE Prolec units we supply meet or exceed ANSI and IEEE standards required for North American grid connections.

What is the benefit of FR3 fluid over mineral oil?

FR3 is a bio-degradable seed-oil-based fluid that has a higher flash point, making the transformer safer and more environmentally friendly.

Can I choose the specific voltage for my region?

Yes, we specialize in US standard ratios like 12.47kV/7.2kV to 240/120V for residential or 480Y/277V for commercial use.

Is the enclosure protected against tampering?

Yes, the "Green Box" enclosure features a specific locking system and overlapping doors to prevent unauthorized access.

Do you supply single-phase units for individual housing?

Yes, we stock single-phase units from 10kVA to 167kVA, which are perfect for local residential distribution.
