Huajidian 2500 KVA liquid immersed distribution transformers are classic 6-10kV fully sealed oil-immersed distribution transformers, employing a non-excitation voltage regulation structure, eliminating the need for power outage voltage regulation, and flexibly adapting to various power distribution system conditions. Addressing the industry pain points of traditional transformers, such as high energy consumption, poor stability, and cumbersome operation and maintenance, this product achieves a comprehensive performance upgrade with low loss, low noise, high strength, and strong corrosion resistance through optimized core structure, high-strength winding technology, and a corrugated fully sealed oil tank design.
The equipment can operate stably for extended periods in harsh environments such as dusty, humid, oily, and slightly corrosive conditions, truly achieving maintenance-free operation. This significantly reduces the long-term operation and maintenance costs of enterprise power distribution systems and is widely applicable to industrial production and civil power distribution projects.
The product uses a high-permeability cold-rolled grain-oriented silicon steel core, combined with a fully oblique joint process and an overall binding and fixing structure, significantly reducing no-load loss and no-load current, fully complying with national energy-saving standards, and effectively reducing long-term electricity expenses for enterprises.
The compact and robust overall core structure effectively suppresses core vibration, reduces additional equipment losses, and simultaneously reduces operating noise, achieving a dual improvement in energy saving and noise reduction, effectively extending the service life of the equipment.
The high-voltage winding adopts a cylindrical structure, while the low-voltage winding is made of oxygen-free copper wire, coupled with Class A insulation materials and special insulating oil. This results in high insulation strength and low partial discharge, easily handling common voltage fluctuations and sudden load changes in industrial environments.
The windings are cured and molded using a special process, resulting in high mechanical strength and excellent short-circuit resistance. They are not easily deformed or damaged by sudden short-circuit impacts from the power grid, significantly reducing the risk of equipment failure and downtime, and ensuring a continuous and stable power supply to the production line.
The oil tank is constructed from high-quality cold-rolled steel plate, with corrugated heat sinks that combine heat dissipation and oil temperature expansion and contraction compensation. This eliminates the need for a traditional oil conservator, achieving a fully sealed structure that completely isolates the transformer oil from external air, moisture, and dust, preventing oil deterioration and equipment corrosion due to moisture.
With its anti-corrosion coating and high-strength chassis structure, the equipment can operate stably in harsh conditions such as dust, humidity, oil, and slight corrosion. It supports customized low-temperature transformer oil, allowing normal operation in environments as low as -25℃, making it suitable for various outdoor and special industrial scenarios.
The 2500 kVA liquid immersed distribution transformers are a mature and classic model with long-term market validation, achieving an optimal balance between cost, reliability, and environmental adaptability. OEM/ODM customization is supported, allowing for customized voltage combinations, capacity specifications, and accessories based on customer power distribution system requirements, meeting the personalized power distribution needs of various industrial projects and civil infrastructure.
1. Project Background: A large metallurgical and chemical industrial park in Northern China. The site experiences high dust levels, high humidity, and the presence of slightly corrosive gases. Frequent start-ups and shutdowns of large equipment cause significant fluctuations in the power grid load. The park's existing traditional transformers have high energy consumption, high failure rates, and short service lives, severely impacting continuous production.
2. Project Solution: The industrial park purchased eight Huajidian 2500 kVA liquid immersed distribution transformers for deployment in the park's core substation, supplying power to the smelting workshop, chemical production line, and supporting equipment. The equipment features a standard fully sealed configuration and industrial anti-corrosion coating, with reserved interfaces for low-temperature customization, adapting to the low-temperature conditions of northern winters.
3. Operational Results: The equipment operated stably for 24 consecutive months without corrosion, oil leakage, or oil deterioration. It effectively withstood sudden load changes, achieving zero short-circuit faults and shutdowns. Compared to older equipment, no-load losses were reduced by 22%, resulting in annual power distribution costs savings of over 18% for the park. The maintenance-free design eliminates routine testing and maintenance work, reducing operating costs by 50%, fully validating the product's energy efficiency and high reliability in harsh industrial environments.
