Frequently Asked Questions
Is this 125 kVA transformer ANSI/IEEE certified?
Yes. It is fully ANSI/IEEE C57 certified and UL/cUL listed, complying with all North American utility standards.
What does "fully sealed" mean for this transformer?
The oil compartment and internal components are completely sealed to prevent moisture, dust, and contamination. It greatly reduces maintenance and extends service life.
What voltage does it convert?
It steps 12470GrdY/7200V down to standard 120/240V for residential and commercial use.
Is it suitable for outdoor and harsh environments?
Yes. Its fully sealed, weatherproof, corrosion-resistant design works reliably outdoors in temperatures from -40°C to +40°C.
Does it require frequent maintenance?
No. The fully sealed structure minimizes maintenance; only annual visual inspections are needed.
What is the lead time and warranty?
Standard lead time is 15–25 business days. All Leilang Electric transformers include a 24-month warranty and professional technical support.
