The SCB Series Epoxy Resin Cast Dry-Type Transformer is a high-performance, maintenance-free power distribution solution, meticulously engineered for safety, efficiency, and long-term reliability. Unlike traditional oil-immersed transformers, this unit uses vacuum-pressure epoxy resin encapsulation for its windings, eliminating the risk of oil leaks, fire hazards, and environmental pollution. It is purpose-built for indoor and semi-outdoor applications where safety, compact installation, and low maintenance are non-negotiable priorities.

The transformer features a robust three-phase structure with a high-quality core manufactured from cold-rolled grain-oriented silicon steel sheets, assembled with a fully inclined lap joint design. This advanced construction minimizes no-load loss, magnetizing current, and operational noise, ensuring optimal energy efficiency. The high-voltage and low-voltage windings are cast in flame-retardant epoxy resin under vacuum conditions, creating a uniform, void-free insulation layer that delivers exceptional mechanical strength, resistance to short-circuit forces, and protection against moisture, dust, and chemical corrosion. Copper windings (aluminum windings are optional) ensure excellent electrical conductivity and low power loss, contributing to high operational efficiency. The unit is supported by a heavy-duty, corrosion-resistant steel frame that provides stable structural integrity, easy installation, and compatibility with standard mounting configurations. Integrated cooling fans, visible at the base of the unit, enable natural air cooling (AN) as standard, with optional forced air cooling (AF) available to enhance load capacity during peak demand. A built-in temperature monitoring and control system, located at the top of the unit, continuously tracks winding temperatures, triggering automatic alarms or shutdowns in case of overheating to prevent damage and ensure operational safety.

Safety is the defining feature of this transformer. The epoxy resin encapsulation is flame-retardant, self-extinguishing, and explosion-proof, eliminating the risk of oil fires and making the unit suitable for installation in populated, sensitive, or high-risk environments such as hospitals, schools, and commercial buildings. The fully sealed windings require no oil replacement or routine maintenance, resulting in low operational costs and a service life of over 30 years under normal operating conditions. The compact, lightweight design allows for installation near load centers, reducing cable losses and infrastructure costs, while the low-noise operation (≤65 dB) complies with urban noise regulations, making it ideal for residential and commercial areas. The unit is also highly resistant to humidity, pollution, and chemical exposure, making it suitable for use in harsh industrial environments.

Rated capacity ranges from 30 kVA to 2500 kVA, with customizable options available for specific project requirements. Rated voltage configurations include 6kV, 10kV, 20kV, and 35kV for high-voltage applications, with 0.4kV as standard for low-voltage output. The unit operates at 50 Hz or 60 Hz, with insulation class F or H and a maximum winding temperature rise of 100 K. Common connection groups include Dyn11 and Yyn0, with customizable tap changers available for voltage regulation. Protection levels range from IP20 (indoor use) to optional IP30 or IP40 with enclosures for enhanced environmental protection.

This transformer is widely used in commercial and public buildings, including shopping malls, hotels, hospitals, schools, and office towers, as well as infrastructure projects such as airports, railway stations, metro systems, and data centers. It is also suitable for industrial facilities, renewable energy power plants, and energy storage systems, where reliable, safe, and efficient power distribution is critical.

Designed and tested to meet international standards including IEC 60076 (Power Transformers) and GB/T 10228 (Chinese National Standard for Dry-Type Transformers), the unit is ISO 9001 certified for quality management, ensuring consistent performance and reliability. Customization options include tailored voltage ratios, connection groups, tap changers, enclosures, and remote monitoring systems to meet specific project and regional requirements.

This SCB Series Dry-Type Transformer combines advanced technology, robust construction, and industry-leading safety features, making it the ideal choice for modern power distribution systems where reliability, efficiency, and environmental responsibility are paramount.
