Product Advantages
High Efficiency & Low Loss
Adopts high-grade cold-rolled oriented silicon steel core and high-conductivity copper windings, the no-load loss is reduced by 15-20% compared with ordinary transformers, and the load loss is optimized, which greatly saves energy consumption during long-term operation and reduces the user's electricity cost.
Stable Voltage Conversion
Precise design of the winding structure ensures accurate voltage conversion from 10KV to 400V, with voltage regulation accuracy up to ±0.5%, effectively avoiding voltage fluctuation and ensuring the normal operation of electrical equipment.
Durable & Reliable
The tank is made of high-quality carbon steel with anti-corrosion coating, which can resist harsh environmental conditions such as humidity, dust and high/low temperature. The pure mineral oil has excellent insulation and cooling performance, preventing insulation aging and extending the service life to more than 20 years.
Safe & Environmental Protection
Equipped with full set of protection devices, including oil level gauge, temperature controller, pressure relief valve and lightning arrester, which can timely alarm and cut off the power in case of abnormal conditions (such as overheating, oil leakage), ensuring the safety of equipment and personnel. The mineral oil used is non-toxic, non-polluting and meets environmental protection standards.
Easy Installation & Maintenance-Free
Compact structure, reasonable layout, convenient for on-site installation and transportation. The transformer adopts a fully sealed design, which effectively prevents moisture, dust and other impurities from entering the tank, avoiding the need for frequent oil change and maintenance. It is essentially maintenance-free under normal use, greatly reducing the user's maintenance cost and labor input.
Application Scenario
The 2500kva oil-immersed distribution transformer (10KV to 400V) is widely used in various fields that require large-capacity power distribution and stable voltage supply, mainly including:
Industrial Parks & Manufacturing Plants
Suitable for large-scale factories, processing workshops, and production lines that need stable 400V power supply, such as machinery manufacturing, chemical industry, metallurgy, and textile industry, ensuring the normal operation of high-power equipment.
Commercial & Residential Areas
Used in large commercial centers, shopping malls, high-rise residential communities, and office buildings, providing stable power for lighting, air conditioning, elevators and other electrical equipment, meeting the daily electricity needs of residents and merchants.
Power Grid Distribution
As an important part of the medium-voltage power grid, it is used in substation construction, urban and rural power grid transformation, and regional power distribution projects, realizing efficient conversion and transmission of 10KV high-voltage power to 400V low-voltage power.
FAQ
Q: What standards does your 2500kva oil-immersed distribution transformer (10KV to 400V) comply with?
Our transformers fully comply with international standards such as IEC 60076, IEEE C57.12.00, and national standards such as GB/T 1094.1-2013 GB20052-2024, which can meet the import requirements of most countries and regions.
Q: What is the service life of this transformer?
Under normal use and regular maintenance, the service life of the transformer is more than 20 years. The high-quality raw materials and advanced production process ensure its long-term stable operation.
Q: Can you customize the transformer according to our specific requirements?
Yes, we provide customized services. We can adjust parameters such as voltage level, capacity, winding material (copper/aluminum), and tank design according to your actual needs, and provide professional technical solutions.
Q: How long is the delivery time for this transformer?
The standard delivery time is 25-35 working days. If you have urgent needs, we can arrange priority production and shorten the delivery time appropriately (subject to specific negotiation).
Q: What kind of after-sales service do you provide?
We provide 1-year free warranty service. During the warranty period, if there is any quality problem caused by the product itself, we will provide free repair or replacement. In addition, we provide lifelong technical guidance and maintenance advice, and our after-sales team will respond to your questions within 24 hours.
Q: How to install and maintain the transformer?
We will provide detailed installation and maintenance manuals in English, including installation steps and precautions. Thanks to its fully sealed design, the transformer is basically maintenance-free under normal use, and there is no need for frequent oil change or regular internal inspection. Only simple external inspection (such as checking oil level and surface condition) is required regularly. If you need, we can also send professional technicians to the site to guide installation and training.
Q: What is the packaging and transportation method of the transformer?
The transformer is packaged in a sealed wooden box, which is moisture-proof, shock-proof and anti-collision.
