Power System Three Phase, 50Hz/60Hz
Certifications IEC 62271-200, IEC 694, GB3906, DIN VDE 0670
The Huajidian Three-Phase Cast Resin Distribution Transformer abandons the insulating oil structure, adopting a dual heat dissipation mode of air self-cooling/forced air cooling, resulting in a compact, safe, and environmentally friendly design. It has undergone a comprehensive upgrade to address the pain points of oil-immersed transformers, such as susceptibility to fire, leakage, and cumbersome maintenance, making it the preferred power distribution device for densely populated areas, precision power consumption areas, and special industrial environments.
Both high and low voltage windings use pure copper conductors, integrally cast in vacuum epoxy resin, resulting in high mechanical strength and excellent short-circuit resistance. The product exhibits extremely low partial discharge, releases no harmful gases during operation, and is less prone to dust accumulation, significantly reducing maintenance workload.
The Three Phase Cast Resin Distribution Transformer core uses high-permeability oriented cold-rolled silicon steel sheets, combined with a beveled joint process, effectively reducing no-load loss and no-load current, meeting national energy-saving standards. The overall robust design minimizes operating noise and vibration, making it suitable for hospitals, schools, and other locations with high acoustic requirements.
A standard air self-cooling system relies on natural convection for energy-efficient and reliable cooling; an optional cross-flow fan upgrade to forced air cooling enhances overload capacity. A temperature controller monitors winding temperature in real time, automatically starting and stopping the fan and triggering an over-temperature alarm, ensuring stable operation of large-capacity equipment.
1. High Safety: Oil-free and flame-retardant, eliminating the risk of fire, explosion, and oil leakage at the source. Its fire resistance rating far exceeds that of oil-immersed transformers.
2. Strong Environmental Adaptability: Moisture-proof, dust-proof, and stain-resistant, it can operate stably for extended periods under complex conditions, ensuring a long service life.
3. Low Maintenance Costs: No need for oil changes or filters; only regular inspections and cleaning are required. Combined with a low-loss design, it saves money in the long run.
4. Compact Size: Small size and light weight allow for direct installation indoors or in basements, saving building space.
A shopping mall in East China has adopted a batch of Three Phase Cast Resin Distribution Transformers. The equipment has operated stably for three years, with low noise and no safety hazards, easily handling peak electricity demand during holidays.
A top-tier hospital in Central China uses customized low-noise transformers to serve core areas such as operating rooms and imaging rooms. There is no oil pollution or vibration interference with medical equipment, and it is suitable for the hospital's constant temperature and humidity environment.
A cloud computing data center in North China is equipped with 20 high-capacity servers. Leveraging strong short-circuit withstand capabilities, maintenance-free operation, and a highly efficient cooling system, it meets the 24/7 uninterrupted power supply requirements of the server cluster.
OEM/ODM customization is supported. Capacity, voltage level, and protection level (IP20/IP30) can be customized according to the power distribution system requirements to adapt to various usage scenarios.
Q1: Can the transformer capacity and voltage level be customized?
A1: Yes. We can customize products with different capacities and voltage levels according to on-site power distribution requirements. IP20/IP30 protective enclosures are also available as options, providing customized solutions.
Q2: Why are dry-type transformers more suitable for shopping malls, hospitals, and data centers?
A2: The Three Phase Cast Resin Distribution Transformer contains no flammable insulating oil, completely avoiding the risks of fire, explosion, and oil leakage, meeting high fire safety requirements; it operates with low noise and vibration, without affecting the indoor environment; the maintenance-free design reduces downtime for maintenance, ensuring power continuity.
Q3: Can this transformer be installed in a building's basement?
A3: Yes. The product is oil-free and leak-proof, will not pollute the basement environment, and its excellent moisture-proof performance allows it to adapt to the damp and poorly ventilated conditions of basements, making it an ideal device for basement power distribution rooms.
