A: Leilang Electric's 37.5 kVA pad-mounted transformer fully complies with ANSI/IEEE C57.12.00 (general requirements), C57.12.28 (enclosure integrity), C57.12.8 (pad-mounted transformers) and C57.12.29 (corrosion protection) standards. It is also UL/cUL listed and CSA approved for North American use.
A: With only 590W load loss and 135W no-load loss, this transformer saves approximately 1,200-1,500 kWh of electricity annually compared to standard models. At an average electricity rate of $0.12/kWh, this translates to $144-$180 in annual savings, with cumulative savings exceeding $3,000 over its 25-year lifespan.
A: All Leilang Electric transformers use 100% high-purity copper windings as standard. Copper provides superior conductivity, lower electrical losses and better corrosion resistance compared to aluminum windings, resulting in higher efficiency, longer lifespan and improved reliability.
A: Yes. While the standard configuration is 12470GrdY/7200V primary to 120/240V secondary, we offer custom voltage ratings including 13.8kV, 13.2kV and 34.5kV. We also support custom feed types (loop/radial), paint colors and accessory configurations to meet your specific project requirements.
A: Standard 37.5 kVA units ship within 15-25 business days. All Leilang Electric transformers come with a 24-month comprehensive warranty from the date of shipment, covering all manufacturing defects. We also provide free technical support and replacement of easily damaged accessories.
A: Yes. It features a NEMA 3R weatherproof enclosure and is designed to operate reliably in temperatures ranging from -40°C to +40°C. The corrosion-resistant coating and domed top design provide excellent protection against rain, snow, dust and UV radiation, making it ideal for harsh outdoor environments.
