33KV Oil immersed Distribution Transformer

The S11 series 33KV Oil immersed Distribution Transformer is a new generation of energy-saving power equipment designed by Sarah Electric factory for medium and high voltage distribution scenarios. Its voltage levels cover 33kV-36kV and rated capacity ranges from 50kVA to 2500kVA, covering two major categories: conventional oil immersed and column mounted. It is suitable for 50Hz working frequency power systems.

Product parameters

Product features

1. The rated capacity covers 50kVA-2500kVA, and the connection group supports mainstream types such as Dyn11 and Yyn0. The 33kV oil immersed transformer can be customized in terms of capacity, voltage, protection level, and installation method (ground installation/column installation) according to customer scenario requirements to meet personalized distribution plans.

2. The fuel tank adopts a fully sealed welding process, combined with anti-corrosion and anti rust coatings, effectively isolating air and moisture from entering, preventing insulation oil from aging and getting damp; Built in high-quality insulating oil, the winding insulation performance is stable, and the ability to resist aging and short circuit impact is strong. It does not need frequent maintenance, and the service life can reach more than 25 years, reducing the later operation and maintenance costs.

3. The column mounted 33kV transformer optimizes the iron core magnetic circuit and reduces electromagnetic vibration, resulting in a low operating noise of 42dB and no noise pollution; It can be installed in residential areas, commercial areas, factory areas and other noise sensitive scenarios, balancing power supply stability and environmental comfort, and adapting to diverse scene needs.

4. The voltage level covers 33kV-36kV, and the high-voltage tap range supports ± 5% and ± 2 × 2.5%, which can flexibly adapt to different voltage fluctuations in the power grid; Equipped with pressure relief valves, oil level gauges, thermometers and other protective devices, real-time monitoring of the operation status of the 33KV Oil immersed Distribution Transformer, and quick warning in case of overload, short circuit, overheating and other abnormalities to ensure power supply safety; Outdoor products are resistant to high and low temperatures, moisture, and salt spray, and are suitable for harsh working conditions.

Selection Guide

1. Determine the rated capacity based on the electricity load, and it is recommended to reserve a margin of 15% -25% to accommodate future load growth;

2. Choose 33kV or 36kV specifications based on the voltage level of the power grid, with priority given to column mounted models in rural/remote areas and conventional models in urban/factory areas;

For scenarios with high requirements for energy conservation and noise, low loss customized models can be selected to further improve operational efficiency and environmental adaptability.
