Product Description

Oil Immersed Distribution Transformer
Model : 20kV Ground  Mounted Oil Immersed Transformer

Product Overview
Oil-immersed distribution transformers play a very important role in the electricity transmission, can be directly converted from the high-voltage power grid to low voltage and used for end-users, due to the small capacity, low voltage, the design of more economic and practicality, so as to be widely used for different applications. TAILI develop ranges of design for different projects and market technical requests, and strive to optimize the design of the distribution transformer to achieve even greater advantages!

Structure

Core

1.Structure: Core is made of high permeability grain oriented cold-rolled silicon steel. The core of the new core, miter joints convolution type iron core, its legs of circular cross section multi-step, the yoke and the core of constant section.
2.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.
 

 

Oil level indicator

1.Visual Indication: Enables operators to quickly assess oil levels via visible scales during routine checks.
2.Simple Structure: Composed of basic components like glass and metal tubes, facilitating easy installation and maintenance, thus cutting costs.
3.Reliable Operation: Functions stably under normal conditions, immune to common electromagnetic and mechanical disturbances.
4.Alarm Capability: Signals abnormal oil levels from leaks or temperature changes, allowing timely intervention to avoid transformer damage.

 

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.
