Product Description

High - efficiency and Low - consumption Outdoor Sealed Oil - Immersed Transformer


 

Product overview

These are outdoor - sealed oil - immersed transformers. They feature a three - dimensional wound iron core with an equilateral triangle arrangement of core columns, eliminating air gaps in the magnetic circuit for tighter winding. This structure boosts performance, cuts losses and noise, balances three - phase aspects, and reduces harmonic components. Suitable for urban, rural, industrial three - dimensional wound iron core they also work well in combination and prefabricated substation setups.

Product features

1. Outdoor-sealed design: Adopts an outdoor-sealed structure, capable of withstanding complex outdoor environments, effectively resisting erosion from wind, rain, dust, etc., ensuring stable operation of internal components and providing reliable protection for long-term outdoor work of the transformer.
2. Three-dimensional wound iron core structure: Core columns are arranged in an equilateral triangle, eliminating air gaps in the magnetic circuit, making windings tighter, improving magnetic circuit utilization, and serving as the core design for performance optimization to enhance overall operating efficiency.
3. High-performance: Can improve operating performance, reduce energy loss and running noise, balance three-phase performance, reduce harmonic components, optimize operating status in multiple dimensions, and meet the needs for efficient and stable power supply.
4. Wide application scenarios: Suitable for urban, rural and industrial power grid transformation, and also compatible with combined and prefabricated substations, covering various power engineering scenarios with strong environmental and scenario compatibility.

 The low-voltage winding of oil-immersed transformer generally adopts the cylindrical structure with copper foil around the shaft except copper wire for small capacity. The high-voltage winding adopts multi-layer cylindrical structure, so that the ampere-turns distribution of the winding is balanced, with small magnetic flux leakage, high mechanical strength and strong short-circuit resistance.
