📊 Product Description
Combined Transformer

This product is mainly composed of two parts: the combined transformer and the meter box. The combined transformer consists of two or three single-phase voltage transformers and current transformers, using 25# transformer oil as the insulating medium. The first and second outlet ends are installed on the panel with porcelain bushings.

The watt-hour meter box is mounted on the side of the combined transformer and consists of a watt-hour meter and a reactive watt-hour meter. It offers high measuring accuracy, light weight, convenient installation, and anti-theft features. This series is suitable for outdoor rated voltage 6, 10, 35kV, and rated frequency 50Hz three-phase systems.

🌡 Environmental Operating Conditions
Ambient Air Humidity: Upper limit +40 ºC, lower limit -15 ºC.
Altitude: < 1000 m (higher elevation requires increased rated insulation levels).
Seismic Intensity: Amplitude intensity of no more than 8 degrees.
Relative Humidity: Daily average no greater than 95%, monthly average no greater than 90%.
Site Safety: No fire/explosion danger, serious pollution, chemical corrosion, or violent vibration.
