Product Description

Oil Immersed Distribution Transformer
Model : 3D Core Oil Immersed Type Transformers

Product Overview
Our company makes 3D wound core oil-immersed distribution transformers to meet market demand for energy-efficient, reliable, and space-saving power distribution solutions, aiming to enhance our competitiveness and contribute to sustainable power supply. 3D Core Oil Immersed Type Transformers for AC 50HZ, rated working voltage of 10kv and below the power system, as petroleum, metallurgy, chemical, textile, light industry and other corporate and relatively dust great place for distribution transformers. This product offers low loss, noise, and partial discharge, with high reliability for stable, efficient operation. Easy for Installation and maintenance. Its compact design takes up little space, suiting different areas.
Features
The three-phase oil-immersed distribution transformer applies new type insulating structure. The iron core is made of high-quality cold-rolled silicon-steel plate. High-voltage winding group is made up of high-quality oxygen-free copper lines and it adopts multi-layer drum type structure. All fasteners have been processed with special treatment to prevent them from loosening.

Structure

Core
1.Material: It is crafted from high - quality, thin - gauge grain - oriented silicon steel laminations.
2.Structure:These laminations are precisely assembled into a 3D structure. This optimizes magnetic flux distribution, minimizing magnetic leakage and core losses.
3.Benefits: The design boosts energy efficiency and load-handling capacity. The tightly-stacked laminations form a continuous magnetic path, which is crucial for the transformer's performance.

High - Voltage Porcelain Insulators
1.High-performance internal insulation. The insulation resistance at 20 kV is not less than 500 MΩ.
2.Ensures high mechanical strength against bending, compression, and seismic forces.

Heat sinks
1.High-efficiency Heat Dissipation:Large-surface - area design maximizes contact with cooling medium (air/oil), enabling rapid heat transfer and efficient dissipation of transformer - generated heat.
2.Optimal Structure:Well-spaced, fin-like structure. Fins arranged to boost natural/forced convection of cooling medium, ensuring smooth fluid flow and preventing heat build - up.
3.Durable Material:Made of high - quality aluminum alloy or copper for great thermal conductivity. Can endure high-temp and mechanical vibration in transformer's operation, ensuring long-term reliability.
4.Corrosion-resistant:Corrosion-resistant materials safeguard heat sinks from rust and degradation, extending lifespan and maintaining heat - dissipation efficiency.
