Huajidian is deeply committed to the research and development of high-quality 3 phase distribution transformers, specifically designed for energy-saving power distribution equipment in AC 50Hz, 10kV and below power systems. Our products utilize a fully sealed corrugated oil tank and a high-permeability magnetic core, offering advantages such as low loss, high insulation, short-circuit resistance, and pollution resistance. They can operate stably in harsh environments such as dust, humidity, and slight corrosion, making them suitable for petroleum, metallurgical, chemical, industrial and mining enterprises, high-rise buildings, commercial and residential areas. Custom specifications are also available.
The core uses high-permeability oriented cold-rolled silicon steel sheets, combined with a core-type core with a fully oblique joint structure, effectively reducing no-load loss and no-load current. Compared with traditional models, the energy saving effect is significant, greatly reducing long-term electricity costs. Simultaneously, the optimized magnetic circuit results in lower operating noise.
The high-voltage winding has a cylindrical structure, while the low-voltage winding can be either cylindrical or foil-type, optimizing leakage flux distribution and significantly improving short-circuit and impact resistance, capable of handling sudden voltage fluctuations in the power grid. All windings use high-purity oxygen-free copper with excellent conductivity, combined with a dedicated insulation structure to enhance insulation strength and reduce the risk of partial discharge.
The oil tank is made of high-quality cold-rolled steel plate, integrally formed using the German Georg corrugated oil tank production line. The corrugated heat sink combines heat dissipation and oil volume compensation functions, eliminating the need for a traditional oil conservator and achieving a fully sealed structure. Completely isolates transformer oil from air and moisture, preventing oil deterioration and insulation dampness, extending equipment life, and eliminating the need for regular oil changes and maintenance; the environmentally friendly anti-corrosion coating on the surface can withstand the corrosive environments of the petroleum and chemical industries, and is not prone to rust and aging during long-term outdoor use.
1. Heavy Industry: Petroleum, chemical, and metallurgical enterprises, dealing with oil pollution, dust, and corrosive environments; the fully sealed structure protects the internal insulation, ensuring continuous production power supply.
2. Urban Construction: High-rise buildings, commercial centers, and residential area power distribution; low loss and low noise, balancing operating costs and environmental protection.
3. Complex Outdoor Scenarios: Mines, drilling platforms, and mountainous outdoor environments; strong weather resistance, adapting to complex climates such as large temperature differences and high humidity, reducing the risk of downtime due to malfunctions.
In 2024, a large petrochemical enterprise in Northwest China selected Huajidian's fully sealed 3 phase distribution transformer for its refinery workshop. This area has long suffered from problems such as oil and gas corrosion, high dust levels, and large diurnal temperature variations. In the year since its commissioning, the equipment has achieved 22% lower no-load losses than the industry standard, with no oil leaks or insulation dampness faults. Maintenance frequency has been changed from quarterly to annual inspections, resulting in a reduction of over 30% in overall electricity and maintenance costs, fully demonstrating the product's adaptability to harsh environments and its long-term energy-saving advantages.
1. Low-loss core and winding design, with no-load and load losses superior to industry standards, resulting in higher long-term cost-effectiveness.
2. Fully sealed corrugated tank isolates from contamination, eliminating the need for regular oil changes and significantly reducing maintenance costs.
3. Reinforced insulation + short-circuit resistant windings withstand sudden short-circuit impacts on the power grid, ensuring more stable operation.
4. Multiple capacity specifications are available, adaptable to voltage levels of 10kV and below, meeting the power distribution needs of different scenarios.
5. Anti-corrosion coating + high-strength casing ensures long-term stable operation in harsh environments and extends service life.
Q1: What are the energy-saving advantages of Huajidian 3 phase distribution transformers compared to ordinary transformers?
A: The 3 phase distribution transformer uses high-permeability, oriented cold-rolled silicon steel sheets and a fully oblique-joint core, reducing magnetic losses at the source; oxygen-free copper windings reduce conductive losses, resulting in lower long-term power consumption and outstanding energy-saving performance.
Q2: Can this fully sealed transformer operate stably in high-humidity, corrosive industrial environments?
A: Yes. The fully sealed corrugated tank completely isolates air and moisture, preventing insulation from getting damp and oil from deteriorating; the surface anti-corrosion coating resists chemical corrosion and rust, making it suitable for long-term use in industries such as petroleum, chemical, and mining.
Q3: What transformer customization services does Huajidian offer?
A: We can customize capacity, voltage level, shell corrosion resistance level, and structure according to the application scenario, including special models such as explosion-proof, dustproof, and high-temperature resistant, meeting the personalized power distribution needs of various harsh working conditions.
