In the booming market of photovoltaic (PV) power stations, selecting the right step-up transformer is crucial. As a specialised transformer manufacturer, ZTelec Yuguang stands out as a trusted partner offering customised step-up solutions tailored to PV station requirements.
PV stations require step-up transformers to raise generation voltage to grid connection levels (e.g., from 0.4 kV/0.69 kV to 10 kV/20 kV/35 kV).
A manufacturer with experience in renewable-energy applications ensures optimum design for voltage rise, efficiency, low losses and ruggedness in harsh outdoor environments.
ZTelec Yuguang boasts decades of experience and offers OEM/ODM customisation, including for ABB and Schneider equipment
Here are typical specifications for the types we provide:
| Type | Rated Voltage (Primary→Secondary) | Capacity Range | Cooling Type | Suitable For PV Station Scenario |
|---|---|---|---|---|
| Dry-Type Step-Up Transformer | 1 kV/0.69 kV → 10 kV / 20 kV / 35 kV | 30 kVA – 6 300 kVA | Air cooled | Inverter room indoor or semi-outdoor PV plant |
| Oil-Immersed Step-Up Transformer | 6 kV/10 kV → 20 kV / 35 kV | 100 kVA – 15 000 kVA | Oil + radiators | Outdoor large-scale PV plant |
| Pad-Mounted Liquid Filled | e.g. 480 V → 12.47 kV / 13.2 kV | 100 kVA – 3 000 kVA | Liquid filled | Utility / community PV installations |
Note: Customisation (voltage, winding, brands such as ABB/Schneider) is available upon request.
In one of our recent projects, ZTelec Yuguang supplied a 2 MW PV farm with a dry‐type 20 kV step-up transformer. The unit was engineered to meet inverter output of 690 V, and stepped up to 20 kV for grid connection. Performance metrics included <0.5% no-load loss, <1.0% load loss at rated load, designed for tropical climates and high humidity. This real-world project underlines our capability to deliver PV-specific step-up transformer solutions.
