7.2kV Single-phase Pole-mounted Transformer

The 7.2kV single-phase pole-mounted transformer is a cornerstone of residential power supply in North America and regions using the US standard distribution system. As a single-phase voltage corresponding to a 12.47kV three-phase distribution system, the 7.2kV transformer is widely installed on power poles in the United States, Canada, Mexico, the Philippines, and other countries, safely and reliably stepping down medium-voltage electricity to a low voltage usable by residential and commercial facilities.

This series of products has obtained UL certification with a capacity ranging from 10kVA to 333kVA, making it an ideal choice for rural electrification, suburban residential development, and small commercial power supply.Application Areas

1. Residential Power Supply

Core application scenario. 7.2kV single-phase transformers are directly installed on utility poles in communities, providing standard 120/240V split-phase power to detached houses and townhouses, meeting daily power needs such as lighting, air conditioning, and home appliances.

2. Rural and Suburban Electrification

In sparsely populated areas, 7.2kV transformers are the most economical and efficient power distribution solution. They are distributed along roads, supplying power to scattered households, farms, and remote communities without the need for expensive substations.

3. Small Commercial Facilities

Suitable for street-side shops, small offices, gas stations, restaurants, and other commercial users with light loads. Single-phase power supply is sufficient to meet the needs of lighting, payment systems, and a small amount of power equipment.

4. Agriculture and Irrigation Systems

Providing power to farms, livestock facilities, and small irrigation pumping stations. 7.2kV transformers can be directly installed on utility poles near farmland, close to load centers, reducing low-voltage line losses.

5. Public Facilities and Streetlights: Dedicated transformers for public facilities such as road lighting, traffic signals, and park lighting, ensuring reliable power supply to these distributed loads.

6. Communication Base Stations: Providing stable single-phase power to communication towers and microwave relay stations in remote areas, ensuring the operation of communication infrastructure.

Core Product Advantages

1. Natively compatible with 12.47kV three-phase networks: 7.2kV is the standard phase voltage of a 12.47kV system, allowing direct connection of one phase from a three-phase line to power single-phase users.

2. Ready to use immediately: Requires no adaptation or modification, fully compliant with North American power company technical specifications.

3. Pole-mounted installation eliminates the need for a distribution room or concrete foundation, saving 30-40% on initial investment compared to pad-mounted or ground-mounted transformers.

4. Utilizes a high-quality cold-rolled silicon steel core, with no-load losses significantly lower than industry standards, complying with DOE 2016 energy efficiency regulations, resulting in significant long-term electricity cost savings.

5. Optional copper or aluminum windings, allowing for flexible configuration based on budget and performance requirements. Copper windings offer higher conductivity and longer lifespan.

6. Multi-standard compatibility: Simultaneously meets IEEE/ANSI, CSA, and IEC standards, supplying the global US standard market. 7. UL/cUL certification optional: For the most demanding North American market, we offer UL certified models to ensure projects pass acceptance smoothly.
