Product Description
333kVA Single Phase Pad Mounted Transformer | 34.5kV, Multiple Safety Protections, Low TCO
Leilang Electric 333 kVA single-phase pad-mounted transformer is a heavy-duty, high-capacity power distribution solution designed for 34.5kV (34500GrdY/19950V) utility networks, built with multiple safety protections and optimized for low total cost of ownership (Low TCO). This oil-filled, compartmental-type unit steps down 34.5kV high voltage to standard 120/240V secondary power while fully complying with ANSI/IEEE, CSA, and DOE 2016 standards. It features a comprehensive safety system including dead-front construction, pressure relief, surge protection, and tamper-proof security. With high efficiency, long service life, minimal maintenance, and energy-saving performance, it delivers ultra-low long-term operating cost and stable power for large residential, commercial, and industrial applications.

Frequently Asked Questions
Is this transformer designed for 34.5kV systems?
Yes. It is specially designed for 34500GrdY/19950V (34.5kV) North American utility grids.
What safety protections are included?
It provides multiple safety protections: dead-front insulation, pressure relief valve, surge arresters, bayonet fuses, tamper-proof lock, and dedicated grounding.
How does it achieve Low TCO?
High efficiency reduces power bills; fully sealed design cuts maintenance; long lifespan lowers replacement cost; no substation needed saves construction expense.
Does it meet North American standards?
Yes. It complies with ANSI/IEEE C57, CSA, and DOE 2016 efficiency standards.
Is it suitable for outdoor harsh environments?
Yes. It operates reliably from -40°C to +40°C with corrosion-resistant, waterproof, and impact-resistant construction.
