800KVA 20KV Pure Copper Oil-immersed Transformer – Industrial Power Distribution and Voltage Stabilization Equipment

 

Currently, conventional transformers in the power distribution industry generally suffer from high losses, poor load stability, and susceptibility to failure during long-term operation. Many companies face challenges such as insufficient equipment durability and weak adaptability to high-voltage conditions when expanding factory capacity or upgrading power grids. To address these issues, this 800KVA 20KV pure copper oil-immersed transformer utilizes all-pure copper winding technology and a new insulation and sealing structure, precisely adapting to high-voltage industrial power distribution scenarios. The equipment can perfectly coordinate with dry-type transformers, box-type substations, High And Low Voltage Switchgear, electric power converters, and Combined Photovoltaic Substations, and is widely used in factory power supply, photovoltaic power plants, urban and rural power grid upgrades, and high-voltage power distribution in industrial and mining enterprises. The product effectively reduces power transmission losses, continuously stabilizes output voltage, significantly reduces equipment failure rates and subsequent maintenance costs, and provides safe, efficient, and long-term transformer protection for various power systems. 

 

Core Product Features

1. Low Energy Consumption and Energy Saving with Pure Copper Winding: The entire unit is wound with high-purity pure copper coils. Compared to aluminum wire equipment, it has superior conductivity and lower heat generation, significantly reducing losses under high-voltage loads. Long-term use can effectively save on enterprise power consumption. It is suitable for 20KV high-voltage stable transformer requirements and operates smoothly without overload risk under full-load 800KVA conditions.

 

Usage Tips

1. Compatible Installation Specifications: The equipment must be installed with the corresponding High And Low Voltage Switchgear and Box Type Substation. The installation environment should be kept dry and well-ventilated, avoiding areas with dust or corrosive gases to prevent affecting insulation performance and equipment lifespan.
