The Huajidian 630 kVA epoxy resin dry type transformer is a mainstream core power distribution device for small and medium-sized factories, commercial complexes, hospitals, data centers, campuses, and residential areas. Compared to traditional oil-immersed transformers, this unit features an oil-free design, incorporating vacuum epoxy resin-cast coils and a high-permeability silicon steel core. It supports both air-cooled (AN) and forced-air-cooled (AF) dual heat dissipation modes. The equipment is flame-retardant, dustproof, moisture-proof, and requires virtually no maintenance, enabling long-term stable and uninterrupted operation. Its safety and adaptability far surpass traditional equipment.
Designed for 24-hour continuous load operation in small and medium-sized factories, this transformer uses a high-permeability cold-rolled silicon steel core with a stepped core structure and fully oblique joint technology. Both no-load and load losses are superior to industry standards. Enterprises can enjoy uninterrupted power supply throughout the year, resulting in significant long-term electricity cost savings and precisely meeting the cost control needs of small and medium-sized projects.
The core employs a professional binding and fixing process, resulting in minimal operating vibration and noise. It will not disturb the surrounding environment and is suitable for noise-sensitive environments such as hospitals, schools, office buildings, and residential areas, achieving green and quiet power supply.
As an oil-free cooling device, the 630 kVA epoxy resin dry type transformer solves the heat dissipation problem of dry-type equipment through a scientific dual-cooling system. The standard air self-cooling mode relies on natural air convection to meet the daily routine load cooling needs. It features a simple structure, extremely low failure rate, and requires no additional power.
For peak power consumption or short-term overload conditions, a bottom crossflow fan can be added to switch to forced air cooling mode, instantly increasing load capacity and easily handling high load pressure, preventing high-temperature overload issues. Equipped with an intelligent temperature controller, it monitors coil temperature 24/7, enabling automatic fan start/stop, high-temperature alarms, and trip protection under extreme conditions, ensuring comprehensive safe operation.
The entire unit features an oil-free design and flame-retardant epoxy resin material, eliminating the risk of fire, explosion, or oil leakage. The equipment boasts excellent dust and moisture resistance, making it suitable for complex environments such as enclosed indoor spaces, basements, and humid conditions. The cast-in structure is stable, with no daily wear and tear, achieving virtually zero maintenance and significantly reducing the long-term operation and maintenance costs of enterprise power distribution systems.
The coil adopts a vacuum epoxy resin integral casting process, resulting in a compact structure and uniform insulation layer, effectively resisting dust, moisture, and electromagnetic interference. A high-precision silicon steel core reduces leakage flux and vibration losses, improving power supply efficiency. A dual heat dissipation system covers all scenarios from daily low load to peak overload, achieving adaptive heat dissipation.
A built-in intelligent temperature control system features multiple protection mechanisms including temperature warning, fan linkage, and power failure tripping. The product complies with IEC international standards and national power industry standards, boasting a stable structure, strong short-circuit resistance, and high impact resistance, capable of withstanding long-term continuous operation and sudden load impacts.
As a professional power equipment manufacturer rooted in China, Huajidian possesses an independent R&D center, standardized production workshops, and a fully automated epoxy resin casting production line. From the intake of raw materials such as silicon steel sheets, oxygen-free copper, and epoxy resin to the shipment of finished products, the entire process involves layered sampling and testing. All equipment undergoes rigorous tests including withstand voltage, partial discharge, temperature rise, and short-circuit impact, ensuring quality that can withstand on-site engineering verification.
The 630 kVA epoxy resin dry type transformer breaks through the limitations of conventional 10kV/11kV standards, supporting OEM/ODM customization. Protection levels, voltage regulation methods, and equipment configurations can be adjusted according to different voltage standards, installation conditions, and project requirements in different regions both domestically and internationally. The factory possesses large-scale mass production capabilities, enabling efficient delivery of large-volume engineering orders and small-batch customized orders without delaying project schedules. Relying on a comprehensive supply chain and logistics system, stable domestic and international supply is achieved.
A medium-sized auto parts manufacturing plant in Jiangsu Province purchased three Huajidian 630 kVA epoxy resin dry type transformers to provide 24-hour uninterrupted power supply for its automated production line, stamping equipment, and supporting electrical systems. This plant has high requirements for power supply stability, energy consumption, and noise control. After commissioning, the equipment operates with low loss and low noise throughout the year, saving over 15% of electricity annually compared to the original oil-immersed transformer. It has been operating stably and without failure for two years, without affecting the factory's office and living areas, and is perfectly suited for continuous industrial production.
Can be directly installed indoors in small and medium-sized office buildings, shopping malls, hotels, schools, and hospitals. It poses no fire hazard, operates with low noise, and eliminates the need for a new outdoor power distribution room, saving construction costs.
Oil-free and pollution-free, providing stable power supply, meeting the high safety and reliability requirements of data centers and precision server rooms.
Compatible with 10kV/11kV industrial power distribution systems, supporting 24-hour continuous factory production. Energy-efficient and durable, reducing long-term electricity costs for enterprises.
Compatible with the 11kV voltage standard used in multiple countries, conforming to international power regulations, making it the preferred power distribution equipment for small and medium-sized infrastructure and industrial projects overseas.
Q1: What are the differences between epoxy resin cast dry-type transformers and open-type dry-type transformers, and how should one choose the right model?
Both models have their advantages: Huajidian epoxy resin cast transformers have strong sealing performance and excellent moisture-proof, dust-proof, and dirt-proof properties, making them suitable for complex and harsh working conditions such as basements and workshops that are damp and dusty. Open-type dry-type transformers have better heat dissipation and are more convenient for daily maintenance, making them suitable for standard indoor power distribution rooms with good ventilation and a dry environment. We can provide professional selection solutions free of charge based on the customer's site conditions.
Q2: Can a 630 kVA epoxy resin dry type transformer be installed in a damp basement?
Yes, it can be installed and used normally. The equipment is oil-free and leak-free. The epoxy resin cast structure has inherent moisture-proof and corrosion-proof properties, which can adapt to the damp environment of a typical basement. For basements with high humidity and poor ventilation, a protective outer shell can be added to further enhance moisture-proof, dust-proof, and condensation-proof capabilities, ensuring long-term stable operation of the equipment.
