1 Phase Pad Ground Mounted Transformer 12470Y 7200 Mount Transformer 51 DBA
The 10 KVA Single-Phase Pad Mount Transformer is a high-reliability, industry-compliant power distribution solution engineered to deliver stable voltage transformation for residential, commercial, and light industrial applications. Designed with precision to meet global standards, this transformer integrates a 12470Y/7200 Grounded Wye Primary and 240/120V Secondary configuration, paired with mineral oil insulation and ONAN cooling technology—ensuring consistent performance, safety, and long-term durability in outdoor and underground distribution systems.
Every component of this transformer is engineered to adhere to strict industry standards, including ANSI, IEEE, NEMA, and DOE 2016 efficiency requirements, with UL and CSA certifications to validate its performance and safety credentials.
- Rated Capacity & Phase Configuration: 10 KVA single-phase design, optimized for small to medium power distribution needs—ideal for residential communities, small commercial buildings, and outdoor public service facilities where single-phase power is required.
- Primary Voltage & Configuration: 12470Y/7200 Grounded Wye Primary, a widely adopted configuration for medium-voltage distribution that ensures safe, balanced power input with enhanced fault protection.
- Secondary Voltage & Output: 240/120V Secondary, perfectly matched to power standard residential and light commercial loads such as lighting, appliances, and small equipment.
- Insulation & Cooling System: Filled with high-grade mineral oil (non-PCB, compliant with ASTM D3487 standards) and ONAN (Oil Natural, Air Natural) cooling system for low maintenance and high reliability.
- Construction & Durability: Enclosed in a tamper-resistant, weatherproof NEMA 3R cabinet with corrosion-resistant epoxy coating, protecting internal components from harsh weather and unauthorized access.

Exceeds DOE 2016 federal energy efficiency requirements by 2-3% with 190W no-load loss and 650W load loss, 15% lower than pre-DOE 2016 models. Saves 2,000-2,500 kWh of electricity annually, qualifying for North American energy rebate programs.
Captive penta-head security bolts require specialized tools to open, preventing casual tampering. Floating nut design prevents bolt removal even if the head is damaged. Integrated padlock provision for additional layered security.
Dead-front compartmental construction eliminates all exposed live parts. Multi-layer protection suite includes bayonet fuses, surge arresters and automatic pressure relief valve. NEMA 3R weatherproof enclosure withstands rain, snow, dust and UV radiation.
KNAN self-cooling system with no moving parts eliminates fan maintenance. Fully sealed oil compartment prevents dust and moisture ingress. Electrical grade mineral oil with oxidation inhibitor extends insulation life.
Native 12.47kV primary voltage, the most common distribution voltage in North America. Supports both loop and radial feed distribution networks. 5-position voltage tap changer compensates for line voltage fluctuations.
