As a professional transformer manufacturer and supplier in China, XUCKY would like to provide you high quality SCB10 dry-type power transformers. Compared with oil-immersed transformers, this type of product has characteristics in terms of safety, fire performance and maintenance requirements, but usually has higher initial cost and relatively large equipment volume at the same rated power.
Magnetic core: Made of high-grade cold-rolled silicon steel sheet laminated, the thickness of a single sheet is usually between 0.23mm and 0.3mm, which can effectively reduce eddy current loss and hysteresis loss. The core is assembled with staggered joints and fastened with non-magnetic materials to ensure structural stability and low operating noise.
Windings: Windings are made of copper or aluminum conductors treated with insulating materials such as fiberglass, Nomex or epoxy. Its structure design includes layered, foil and concentric winding, among which foil winding has better short-circuit tolerance and heat dissipation performance.
Insulation systems: Classified according to the temperature rise limits in IEC 60076-11, including common categories such as Class B (130°C), Class F (155°C), Class H (180°C) and Class C. Epoxy resin casting process is widely used in the manufacture of medium voltage transformers, which can provide good mechanical properties and chemical corrosion resistance.
Cooling system: Natural air cooling (AN) is used as standard for low power transformers. For higher rated transformers, a forced air cooling (AF) system can be used, which, in conjunction with fan operation, can increase output capacity by approximately 30% to 50%. Some transformer designs also integrate radiators or ventilation duct systems to optimize airflow around the windings and core.
Accessories: We offer a wide range of enclosure options, from open frame construction for clean indoor environments to closed enclosures with IP23 or IP54 protection for dusty or outdoor environments. These enclosures ensure adequate ventilation while effectively blocking the ingress of foreign matter and preventing accidental contact with live parts.
Dry-type power transformers work on the principle of electromagnetic induction. When alternating current passes through the primary winding, alternating magnetic flux is generated in the iron core, which passes through the secondary winding, thereby inducing electromotive force in the secondary winding. By adjusting the turns ratio of primary and secondary windings, the voltage can be increased or decreased, and the transmission and conversion of electric energy can be completed. The whole energy transfer process is carried out in a dry environment composed of solid insulating media, without liquid cooling or insulating media.
Safety: No flammable liquid insulating oil, fundamentally eliminate the risk of fire and environmental hazards, meet the strict safety standards of high-rise buildings, hospitals, data centers and other places.
Low maintenance: No need for insulating oil monitoring and treatment, no need for regular maintenance such as oil quality testing (such as dissolved gas analysis), no hidden danger of oil leakage, and low comprehensive cost throughout the life cycle.
Environment-friendly: No risk of oil leakage polluting soil or water, in line with LEED, BREEAM and other green building evaluation standards.
Flexible installation: SCB 10 dry-type distribution transformers are suitable for indoor and confined space installation, and can adapt to a wide range of temperature(-30℃ to +50℃) operation under the corresponding insulation class. Low noise operation: By optimizing the core clamping and winding structure design, the operating noise is usually 45 - 65 dB (1 meter distance), suitable for office buildings, residential areas and other noise sensitive environments.
Commercial buildings: Distribution systems for shopping malls, hotels, airports and other places, taking into account safety and space utilization.
Industrial field: Manufacturing plants, refineries, mines, etc. for local power conversion and motor drive power supply.
Renewable energy: Our resin-insulated dry-type transformer can be used in solar power stations and wind farms to achieve voltage rise and fall to adapt to grid access or local consumption.
Data center: Provides stable power for IT equipment with high efficiency and low harmonic distortion.
Urban infrastructure: Subway, hospitals, high-rise buildings and other places with strict fire safety requirements, replace oil-immersed transformers.
Periodic inspection: Including visual inspection of insulation condition, tightness of connection points and dust accumulation; temperature rise test shall be carried out under load every year.
Temperature monitoring: Continuous monitoring of winding and core hot spots by built-in PT100 sensors or infrared cameras to ensure that temperatures do not exceed insulation class limits.
Partial discharge detection: On-line or off-line partial discharge measurement of medium and high voltage (>10kV) transformers to evaluate the insulation system status.
Cleaning and maintenance: Using compressed air or vacuum cleaning to clean the heat dissipation channels and surfaces, and maintain smooth ventilation; avoiding using water or chemical solvents to directly clean insulating parts. Life management: Expected service life of 25 - 30 years under normal maintenance conditions; insulation resistance testing is recommended every 3 to 5 years to assess dielectric strength.
Environmentally-friendly materials: Bio-based epoxy resin and recyclable core materials are used to reduce the impact of the product life cycle on the environment.
Intelligent monitoring: Integrated IoT sensors enable real-time collection and analysis of temperature, humidity, partial discharge and vibration data, and support predictive maintenance based on cloud platforms.
Efficient design: By optimizing magnetic circuit structure and winding materials (such as amorphous alloy core), achieve higher energy efficiency, in line with EU ecological design and US Department of Energy Tier 2 energy efficiency standards.
Compact structure: Application of indirect liquid cooling and other advanced heat dissipation technology, while ensuring power density while reducing the size of equipment, to adapt to urban space constraints.
Modular design: Modular winding and core structure, easy to transport, installation and subsequent expansion transformation.
International standards: IEC 60076-11 (general standard for dry-type transformers), IEEE C57.12.01 (dry-type distribution transformers)
Safety Code: IEC 61140 (Protection against Electric Shock), NFPA 70 (NEC) Article 450 for North American installations
Environmental requirements: RoHS compliance and REACH chemical registration regulations.
Dry-type power transformers continue to gain adoption as industries prioritize safety, sustainability, and reliability. Their technical advancements, coupled with stringent regulatory requirements, position them as a cornerstone of modern electrical infrastructure, particularly in urban and environmentally sensitive settings.
