315KVA 10KV Pure Copper Winding Epoxy Resin Cast Oil-immersed Transformer: High-Efficiency Energy-Saving Power Distribution Equipment

 

Currently, most ordinary oil-immersed transformers on the market use aluminum wire windings, which suffer from high losses, severe heat generation, and insufficient load-bearing capacity—industry pain points. Many power projects experience equipment overload tripping, unstable power supply, and short service life, significantly increasing project upgrade and maintenance costs. To address these issues, our factory has launched a 315KVA 10KV Oil-immersed transformer (Pure copper). Utilizing pure copper windings and an epoxy resin casting process, the core configuration of the equipment has been upgraded, comprehensively optimizing conductivity and insulation protection. This equipment boasts low operating losses, high current carrying capacity, and outstanding stability, making it perfectly compatible with various complete sets of power equipment. It is commonly used in conjunction with Dry Type Transformers, High And Low Voltage Switchgear, and Electric Power Converters, and is widely applied in industrial and mining enterprises, municipal power grids, photovoltaic power plants, and park power distribution. It can also be integrated into Box Type Substations and Combined Photovoltaic Substations, providing long-term, energy-saving, and stable high-voltage power distribution guarantees for various power projects, effectively reducing long-term power losses and equipment replacement costs.

 

Core Product Features

1. Low-loss power transmission with pure copper windings: The equipment uses brand-new pure copper coil windings, which have high conductivity and low resistance losses. Compared with traditional aluminum wire transformers, no-load and load losses are significantly reduced, heat generation is more uniform and less prone to overload, resulting in excellent Energy Efficiency during long-term continuous operation, making it suitable for high-intensity uninterrupted power distribution conditions.

2. Epoxy Reinforced Insulation: The windings are integrally sealed with epoxy resin, resulting in a compact and seamless structure that effectively isolates moisture and dust corrosion. It exhibits outstanding resistance to high-voltage breakdown and is suitable for complex and harsh operating environments such as outdoor areas, mining areas, and coastal regions.

 

Practical Maintenance Tips

1. When using the equipment with Combined Photovoltaic Substations, the output voltage parameters of the Electric Power Converter should be checked regularly to ensure the transformer load is within the rated range, avoiding prolonged overload operation that could affect the equipment’s lifespan.

 

Frequently Asked Questions (FAQ)

Q1: What is the biggest advantage of the pure copper winding model compared to ordinary oil-immersed transformers?

A1: Compared to conventional oil-immersed transformers, pure copper windings offer superior conductivity, lower energy consumption, lower temperature rise, and significantly longer overload resistance and lifespan than aluminum wire models. Long-term use can substantially save energy costs, making it suitable for power projects operating at high frequencies for extended periods.

 

Q2: Can this equipment be assembled with prefabricated substations and high/low voltage switchgear?

A2: Yes. The product parameters are standardized, with strong compatibility, flexibly adaptable to Box Type Substations and High and Low Voltage Switchgears. It can also be paired with Dry Type Transformers to form complete power distribution systems, suitable for most industrial and new energy power distribution projects.

 

Q3: Is daily maintenance of the equipment complex?

A3: Operation and maintenance are simple and convenient. The fully sealed oil-immersed structure with epoxy casting protection is not prone to oil leakage and the insulation layer is not prone to aging. Frequent replacement of insulating oil is unnecessary; only periodic checks of oil level and operating temperature are required, making it suitable for unattended power distribution scenarios.

 

Q4: What after-sales guarantees are provided?

A4: The equipment undergoes full-scale withstand voltage and load testing at the factory, meeting quality standards. A long-term warranty is provided for the entire machine. Parameter customization is supported, and installation guidance and technical support services are available. During the warranty period, non-human-caused damage can be repaired and parts replaced free of charge, eliminating concerns about project operation and maintenance.
