Transformers

As a reliable pole mounted transformers manufacturer, NPC Electric specializes in designing and producing high-performance transformers for rural electrification and power distribution networks. Our pole mounted transformers are compact, durable, and ideal for overhead line installations. We offer both single phase pole mounted transformers and three phase pole mounted transformers, designed for residential, commercial, and utility applications.
Each distribution transformer is built with high-quality materials, ensuring superior efficiency, low losses, and long service life. With strict testing and compliance to IEC and ANSI standards, NPC Electric delivers dependable power transformer solutions for global markets.

There are two main pole mounted transformers types commonly used in modern power distribution systems: the Conventional Type Single Phase Pole Mounted Transformer and the Completely Self-Protected Single Phase Pole Mounted Transformer. The conventional type is designed for general residential and rural power networks, providing stable voltage conversion and reliable performance.
The completely self-protected transformer includes built-in protection devices such as circuit breakers, lightning arresters, and fuses, ensuring enhanced safety and reduced maintenance. Both transformer types are compact, easy to install on utility poles, and ideal for distribution transformer and power transformer applications in remote or suburban areas.

Pole mounted distribution transformers are widely used in overhead power systems to step down high-voltage electricity for residential, commercial, and rural networks. These transformers are compact, cost-effective, and easy to install on utility poles, minimizing land use and maintenance costs.
NPC Electric offers both single phase pole mounted transformers for light-load rural distribution and three phase pole mounted transformers for higher-capacity industrial and commercial applications. Each unit is designed as an oil immersed transformer, ensuring efficient cooling, long service life, and reliable performance. Built to IEC and ANSI standards, our pole mounted distribution transformers deliver safe, stable, and energy-efficient power solutions worldwide.

At NPC Electric, every pole mounted transformer and distribution transformer is manufactured under strict transformer testing and quality control procedures to ensure safety, performance, and reliability. Each unit — including oil immersed transformers, substation transformers, and pole mounted distribution transformers — is thoroughly inspected for electrical insulation, load loss, temperature rise, and dielectric strength. Our transformer testing process follows IEC, IEEE, and ANSI international standards, using advanced equipment to simulate real operating conditions. In addition, oil quality and protective devices are tested to guarantee long service life and stability. As a trusted transformer manufacturer, NPC Electric also provides third-party inspection and factory acceptance tests (FAT) to ensure every pole mounted transformer meets the highest global quality benchmarks before delivery.
