As a professional manufacturer of Dry Type Transformers, Youbian relies on its standardized dust-free production workshop and mature pouring process. With reliable product quality, it has become a widely recognized local electrical equipment supplier in China, capable of providing high-quality dry-type transformers to global buyers, engineering contractors, and foreign trade customers.
A Dry Type Transformer is an environmentally friendly power transformer that does not use oil. It differs from traditional oil-immersed transformers as it does not require insulating oil as a heat dissipation and insulation medium. Instead, it relies on natural air cooling to achieve temperature reduction. It completes high and low voltage voltage conversion, power load regulation, and circuit isolation based on the principle of electromagnetic induction, ensuring stable power distribution system voltage and safe power transmission. The dry-type transformers we produce are made by pouring epoxy resin as a whole, with strong overall insulation and excellent fire resistance and flame retardancy. They are specially designed for indoor, densely populated, and high-security scenarios as dedicated power distribution equipment.
When many purchasing customers are selecting models, they often struggle with the applicable scenarios of dry-type transformers and oil-immersed transformers. Although the core functions of these two devices are the same, there are significant differences in structure, safety, and applicable environments. We have summarized the core differences from the perspective of actual engineering:
Dry Type Transformer uses natural air cooling and an epoxy resin casting sealing structure, without any insulating oil; Oil Immersed Transformer relies on circulating insulating oil for cooling, and the equipment has its own oil storage structure, resulting in a larger overall volume.
Dry-type transformers are non-flammable, non-explosive, and have no leakage risks, and have extremely high fire safety levels, making them suitable for densely populated areas; Oil-immersed transformers have the risk of oil leakage and fire, and are only suitable for outdoor and open areas for installation.
Dry-type transformers are dust-proof and moisture-proof, and require no maintenance after installation; Oil-immersed transformers need regular checks of oil level, oil quality, and sealing status, resulting in higher long-term operation and maintenance costs.
Oil-immersed transformers have a lower unit price and stronger overload capacity, and are mainly used in outdoor large-power power grid projects; Dry-type transformers have a higher cost, and are mainly used in indoor high-end, high-security standard power distribution projects.
Relying on its core characteristics of safety and environmental protection, low noise and stability, and maintenance-free, the Dry Type Transformer is specifically suitable for various scenarios such as enclosed, indoor, densely populated areas, and those with strict fire safety requirements. It is the preferred equipment for high-end power distribution projects:
- Power distribution projects for public buildings like urban commercial complexes, large shopping malls, office buildings, and hotels;
- Power supply projects for densely populated areas such as residential communities, hospitals, and schools;
- Indoor power distribution scenarios in industrial parks, dust-free workshops, and intelligent factories;
- Special enclosed power projects like subways, underground pipe galleries, and indoor substations.
Compared to other power distribution equipment, Dry Type Transformer has simple maintenance and a low failure rate. However, regular daily maintenance can effectively extend the equipment's service life and ensure operational stability. We provide professional engineering maintenance suggestions:
- Regular dust cleaning: Regularly clean the surface of the equipment and the cooling air ducts of dust and debris to avoid accumulated dust affecting the cooling effect and preventing local overheating.
- Routine insulation testing: Test the insulation performance and operating temperature of the equipment every quarter, check if the cast shell has any cracks or aging phenomena, and promptly identify potential safety hazards.
- Check operating noise: During daily inspections, pay attention to the operating sounds of the equipment. If abnormal sounds or abnormal vibrations occur, stop the machine for inspection to avoid running with faults.
- Maintain a dry and ventilated environment: The equipment installation room should be kept dry and ventilated to avoid long-term dampness and water accumulation, and prevent the equipment from getting damp and affecting its insulation performance.
A1: It is not recommended. Dry-type transformers do not have outdoor waterproof and anti-aging protection designs. Long-term outdoor use is prone to moisture accumulation and accelerated aging, and they are only suitable for indoor enclosed power distribution environments.
A2: No. The product is oil-free and does not require replacing the insulating oil. It is almost maintenance-free and only requires regular inspection and cleaning, significantly reducing operation and maintenance costs.
A3: Yes. As a professional manufacturer, we can customize according to the voltage level, capacity, and installation size of the customer's project. It can be adapted to various domestic and international power distribution projects.
