200kVA Power Pole Transformer 34500V To 120V FR3 Oil, ≤55dB Outdoor Pad Mounted
Leilang Electric 200 kVA single-phase pad-mounted transformer is a high‑capacity, environmentally responsible distribution solution built for 34500V utility networks, delivering stable 120/240V output with exceptional quiet performance. Engineered with eco‑friendly FR3 vegetable-based insulating fluid in place of traditional mineral oil, this unit offers superior biodegradability, fire safety, and environmental compatibility for residential, commercial, and sensitive public areas. It operates at ≤55 dB sound level—quieter than normal conversation—while stepping down 34500V primary to standard 120/240V secondary power. Fully compliant with ANSI/IEEE C57, DOE 2016, and CSA standards, it combines high efficiency, long service life, and low maintenance to support sustainable urban and rural power distribution.

- Wide Voltage Conversion: 34500V to 120/240V - Directly steps down 34500V high-voltage grid power to safe, usable 120/240V. Optimized for North American 35kV-class distribution systems with stable voltage regulation under varying load conditions. 5-position tap changer supports flexible on-site voltage adjustment.
- Eco-Friendly FR3 Insulating Oil - 100% biodegradable plant-based FR3 fluid that is non-toxic, non-hazardous, and safe for soil and water. Higher fire point than mineral oil for improved public safety. Ideal for parks, residential areas, wetlands, and green projects with extended insulation and transformer lifespan.
- Ultra-Quiet ≤55 dB Operation - Engineered low‑noise core and stiffened tank structure. ≤55 dBA during full load - suitable for noise‑sensitive zones. Perfect for neighborhoods, schools, hospitals, and offices with no disruptive humming even under heavy loading.
- ANSI/IEEE & DOE 2016 Compliant - Meets or exceeds ANSI/IEEE C57.12 series standards. Complies with DOE 2016 energy efficiency mandates. Rugged outdoor enclosure meets IEEE C57.12.28 integrity. Factory tested for safety, loss, and thermal performance.
- Heavy-Duty Outdoor Design - Corrosion‑resistant coated steel tank with domed top prevents water pooling. Stainless steel hardware & hinges with tamper-resistant lock assembly. All-weather reliability for long‑term outdoor use.

It converts 34500V primary to standard 120/240V secondary, making it ideal for North American 35kV-class utility systems.
FR3 is a natural ester biodegradable insulating fluid made from renewable resources. It is non-toxic, fire-resistant, and safe for the environment—much safer than mineral oil for public and green spaces.
It runs at ≤55 dBA, quieter than typical conversation. It is suitable for residential areas, schools, and hospitals where low noise is required.
Yes. It features a weatherproof, corrosion-resistant steel enclosure, domed top, and stainless steel fittings for long‑life outdoor performance.
Yes. It fully complies with ANSI/IEEE C57, DOE 2016 efficiency, and CSA requirements for utility‑grade distribution transformers.
Standard lead time is 15-25 business days. All Leilang Electric transformers include a 24-month warranty and lifetime technical support.
