| High Light | 50kVA Single Phase Pad Mounted Transformer ，Single Phase Pad Mounted Transformer 13.8kV ，highline transformer pads 60Hz | ||
Leilang Electric 50 kVA single-phase pad-mounted transformer is a turnkey power distribution solution purpose-built for North American 13.8kV utility grids, delivering industry-leading safety and cost efficiency. Designed to step down 13800GrdY/7968V primary voltage to standard 120/240V secondary power, this unit features a fully insulated dead-front construction that eliminates all exposed live parts, ensuring zero electrocution risk in public areas.
Its all-in-one integrated design eliminates the need for dedicated substations or control rooms, allowing direct installation on a simple concrete pad with minimal site preparation. Fully certified to ANSI/IEEE C57.12.00, C57.12.28, CSA and DOE 2016 standards, it achieves 98.95% overall efficiency with ultra-low 48 dBA noise operation. Built with 100% copper windings and a robust weatherproof enclosure, it provides maintenance-free service for over 25 years, making it ideal for medium-density residential communities, small commercial centers and public facilities.

Leilang Electric's 50 kVA transformer features a Compartmental-Type II dead-front design where all high-voltage components are completely sealed and insulated within the steel cabinet. There are no exposed live parts anywhere on the unit, eliminating the risk of accidental electrocution for the public and utility workers.
No. Its all-in-one integrated design eliminates the need for dedicated substations, control rooms or any additional civil engineering. It can be installed directly on a simple concrete pad, reducing construction costs by up to 60% and cutting project timelines from months to days.
Yes. It is specifically engineered for the 13800GrdY/7968V standard distribution system used across most of North America. It fully complies with all ANSI/IEEE C57 utility standards and can be directly connected to existing 13.8kV networks.
It achieves an impressive 98.95% overall efficiency with only 166W no-load loss and 640W load loss. This exceeds DOE 2016 federal requirements and saves approximately 1,500-1,800 kWh of electricity annually compared to standard transformers, resulting in significant long-term cost savings.
It operates at an ultra-quiet 48 dBA sound level, which is quieter than normal background conversation. This makes it ideal for installation in residential neighborhoods, near schools and hospitals, and other noise-sensitive environments.
Standard 50 kVA units ship within 15-25 business days. All Leilang Electric transformers come with a 24-month comprehensive warranty covering all manufacturing defects. We also provide free lifetime technical support and replacement of easily damaged accessories.
