4000KVA 35KV High Efficiency Oil-immersed Transformer: Energy-Saving Power Supply Equipment for Industrial Power Grids

 

Currently, the high-voltage power transmission and transformation industry generally suffers from high equipment energy consumption and poor operational stability. Many industrial and mining enterprises and power plant projects often face rising maintenance costs due to the high losses and weak adaptability of aging transformer equipment. To address these industry challenges, we have launched the 4000KVA 35KV High Efficiency Oil Immersed Transformer. Based on optimized core winding technology and energy-saving structural design, it is precisely adapted to high-voltage power distribution scenarios. This equipment can effectively reduce no-load and load losses, stabilize 35KV high-voltage transmission voltage, significantly reduce long-term energy consumption and the probability of downtime, and is widely applicable to various power engineering projects such as factory power distribution, photovoltaic power plants, and industrial and mining power grids. In a complete power supply system, this Oil-Immersed Transformer can be flexibly paired with Dry Type Transformers and Box Type Substations, and is also compatible with High And Low Voltage Switchgear, Electric Power Converters, and Combined Photovoltaic Substations, demonstrating its strong adaptability.

 

Core Product Features

1. Ultra-Low Energy Consumption Design: Utilizing a high-permeability silicon steel core and optimized winding layout, energy consumption is reduced by more than 15% compared to traditional equipment. Long-term operation can significantly save on enterprise electricity costs, making it suitable for high-power, long-term continuous power supply scenarios.

 

Usage Tips

1. During equipment operation, the insulating oil level and temperature should be checked regularly to avoid prolonged overload operation, which can effectively extend the equipment’s service life and ensure stable grid operation.
