Single phase pole mounted transformers designed and produced are normally used for stepping utility distribution voltages (from 2400V to 34500V) down to lower utilization voltages. Although some are used for stepping down to commercial and industrial voltages such as 277V, 240/480V, 2400V and 4800V, most are used for stepping down to the single phase voltage of 120/240V.
These transformers also used for small substation, miscellaneous applications and can serve to step up voltages.
Designs and productions of single phase are available in two types: single phase pole mounted conventional transformer and completely self protected (CSP) transformer. Power rating up to 167kVA.
The single-phase fully complies with or even exceeds international standards such as ANSI/IEEE, CSA, and DOE. Single-phase has UL/cUL, CSA, IEEE and other certificates. It has been exported to North America, Central and South America and other markets in large quantities.
Single phase pad mounted transformer has UL/cUL, CSA, CESI, IEEE certifications. In addition, the 1-phase pad mounted transformer also has SGS, CSA and other third-party inspection reports.
Complete after-sales service and installation teams in Canada, USA, Ecuador, etc. Provide 24 hours of technology and consulting services. There are local cooperation after-sales service teams with rich experience in power engineering and timely services.
Not only produces transformers, but also provides the best solution for your power project. Such as mines, factories, renewable energy power generation (wind power, solar power and BESS, etc.) to provide the best transformer solutions.
More than 20 years of experience in exporting transformers, and the team of engineers is particularly professional and proficient in various international standards. No matter which country you are from, the team of engineers can design and produce according to your requirements and technical parameters.
A strict quality control system to ensure the high quality of each transformer. There are also UL third-party inspection agencies to conduct supervision factories every three months. Therefore, you can fully trust the transformer. The production time of conventional power distribution transformers is 6-8 weeks.

Quality System ISO 9001 certified | Meet DOE Energy Efficiency Standard or exceeds ANSI/IEEE and CSA standards
The following additional features are all standard on self protected type CSP units only:
All transformers are tested in strict accordance with the latest revision of applicable ANSI, IEEE, CSA, DOE, NEMA, and AS with test reports available by serial number of the transformer.
Routine tests are:
The design performance tests include the following:
They are primarily used for stepping utility distribution voltages (from 2400V down to 34500V) down to lower utilization voltages. Most are utilized for stepping down to the single phase residential/commercial voltage of 120/240V, as well as for small substations and miscellaneous voltage adjustment applications.
They are supplied in two primary configurations: the conventional single phase pole mounted type and the completely self protected (CSP) type. The standard power ratings for these units go up to 167kVA.
The single phase transformers fully comply with or exceed major international standards including ANSI/IEEE, CSA, and DOE energy efficiency requirements. They carry official certificates such as UL/cUL, CSA, and CESI.
While conventional types include lifting lugs, arrester mounting pads, and standard bushings, the CSP (Completely Self Protected) configuration builds on this by adding integrated protective components: a primary protective link inside the high voltage bushing, an attached surge arrester, a secondary circuit breaker, and an external operating handle with emergency overload reset capabilities.
Every individual unit undergoes strict routine testing in accordance with ANSI, IEEE, CSA, DOE, and NEMA specifications. These include a leak test, polarity and phase relation tests, resistance validation, load and no-load loss measurements, excitation current calculation, applied/induced voltage tests, a ratio test, and full-wave impulse validation.
Under strict standardized quality management systems, the typical production lead time for conventional power distribution transformers spans between 6 to 8 weeks.
