Power Transformer 66KV-330KV
Tengyi power transformers efficiently transfer electrical energy between circuits, adjusting voltage levels for safe and effective power distribution and utilization.

Distribution Transformer
Tengyi distribution transformers provide reliable, efficient voltage reduction for safe power distribution to residential and commercial end-users, typically used to convert primary distribution voltages (like 11kV or 33kV) to lower utilization voltages (like 400V/230V).

Three Phase Pad Mount Transformer
Our three-phase pad-mounted transformer is a ground-level, enclosed unit that steps down voltage for underground residential and commercial power distribution, mostly suitable for commercial centers, residential areas, industrial and mining enterprises, hospitals, schools, airports, stations, ports, subways and other places.

Single Phase Pad Mount Transformer
Tengyi’s single-phase pad-mounted transformer provides compact, reliable voltage reduction for localized underground distribution to residential and small commercial areas. Designed for outdoor installation on a concrete slab or pad, it serves as a crucial component in the electrical grid, typically stepping down higher distribution voltages (like 15kV, 25kV, or 35kV) to the standard single-phase utiiization voltage (l20/240V,
120/208V) used to power residential homes, small businesses, and light commercial loads.

Single Phase Pole Mount Transformer
Tengyi single-phase pole mount transformers step down distribution line voltage for residential customer service connections and provide durable, efficient overhead voltage transformation for reliable residential and rural power service.

Prefabricated Substation
Tengyi prefabricated substation is a compact, factory-assembled unit for high/low voltage power distribution, and is an integrated power distribution solution that combines high-voltage electrical equipment, power transformers, and low-voltage electrical equipment.

Dry Type Transformer
Our dry-type transformer with high and low voltage winding is sealed with the thin layer epoxy resin, which has the advantages of flame retardant, self-extinguishing, moisture-proof and heat dissipation. lt can go deep into the load center, like high-rise buildings, airports, docks, power plants, residential areas, complete sets of substation, and other places.

Renewable Energy Transformer
Unlock the full potential of your wind, solar, and storage projects. Our Renewable Energy Transformers are not merely adapted, they are purpose-built to manage intermittent outputs, ensure grid code compliance, and maximize energy harvest.
Wide Applications
Tengyi products cater to a wide market, offering innovative, high-quality solutions for diverse utility, industrial, commercial, and residential applications.

Data Center
Transformers for data centers ensure clean, stable, and redundant power to maximize uptime and protect sensitive server equipment from electrical disturbances.

Industrial Applications
Factories and production plants that rely on transformers to power machinery and operations. Used in manufacturing facilities to power machinery that operates at different voltage levels.

Power Transmission
Essential in power plants to step up voltage for transmission over long distances, and then step down voltage for distribution to residential and commercial users.

Transportation System
Involved in the development and maintenance of transportation networks, such as roads and railways, that use transformers for electrification and operational power needs.

Renewable Energy
Businesses focused on renewable energy sources, such as wind and solar, that use transformers to integrate power into the grid and manage energy storage systems.

Construction
Large construction projects, including residential, commercial, and infrastructure, require transformers to provide power during and after construction.
