SC(B)10 series 10~20kV resin insulated dry-type power transformer
Characteristic Description of SC(B)10 Transformer
The series’ most prominent feature is fire-safe encapsulation: using Vacuum Pressure Gelation (VPG) technology, Class F (155°C) or Class H (180°C) epoxy resin is injected into winding micro-pores, creating a dense insulation layer. This design earns it an F1 fire rating (per IEC 60726) and ensures zero toxic emissions during high temperatures or fires— a critical advantage for enclosed spaces where air quality and fire containment are paramount.
The low-loss magnetic system sets the SC(B)10 apart from conventional models: laser-scribed silicon steel cores with step-lapped joints minimize no-load losses, outperforming national standards and reducing energy waste. This efficiency translates to lower operational costs and a smaller carbon footprint, making it a sustainable choice for long-term use.
For heat management, the transformer uses advanced cooling with axial air ducts and Nomex® insulation. This system allows it to handle temporary overloads without performance degradation, ensuring stability during peak power demands. The combination of passive and active cooling elements balances efficiency and reliability, even in high-heat environments.
To resist harsh conditions, the SC(B)10 offers IP54 or IP66 protection levels (IP66 optional) with salt-spray tested coatings (per ISO 9227 C5-M). This makes it suitable for coastal or offshore use, where corrosive saltwater and humidity can damage standard transformers. The robust enclosure shields internal components from dust, water, and chemical exposure.
Smart monitoring via embedded Pt100/Pt1000 sensors tracks winding temperature, insulation capacitance decay, and harmonic distortion. This real-time data enables proactive maintenance, allowing operators to identify potential issues before they escalate into failures. The integration of monitoring technology enhances reliability and reduces downtime for critical applications.
The SC(B)10 dry-type transformer features a rated voltage range of 10kV to 20kV, positioning it as a medium-voltage solution compatible with commercial, industrial, and critical infrastructure grids. Its rated capacity range supports loads from small data centers to large hospitals, ensuring scalability across diverse applications.
Its insulation class (Class F or H) is selected based on operating temperature requirements, with epoxy resin providing superior dielectric strength and thermal stability. The protection level is IP54 as standard (IP66 optional), shielding internal parts from dust and water ingress. It also complies with IEC 60726 fire safety standards, meeting international safety regulations for high-stakes environments.
Cooling is air-cooled via axial ducts, leveraging natural and forced air circulation to maintain safe temperatures. The transformer is equipped with smart monitoring sensors (Pt100/Pt1000) that track critical metrics in real time, with optional integration into building management systems for centralized control. These features enhance operational visibility and efficiency.
In hospitals, the SC(B)10 powers life support equipment, operating rooms, and patient monitoring systems. Its fire-safe design and stable output prevent safety risks and service interruptions, ensuring uninterrupted care for patients. The low noise operation and zero toxic emissions also make it suitable for sensitive medical environments.
For data centers, the transformer ensures stable voltage for high-density servers and storage devices. Low harmonic distortion and smart monitoring avoid data loss from power fluctuations, while its compact design fits into limited server room spaces. The fire-safe construction aligns with data center fire codes, protecting valuable IT infrastructure.
On offshore platforms, the SC(B)10’s salt-spray resistant coatings and IP protection withstand corrosive marine environments. It powers drilling equipment, navigation systems, and crew facilities, delivering reliable performance in harsh offshore conditions where maintenance access is limited.
The transformer is also ideal for commercial high-rises and industrial plants with strict fire codes. Its oil-free design eliminates oil leak or fire risks, while its efficiency and durability reduce operational costs. Whether in shopping malls, manufacturing facilities, or office towers, it provides a safe and reliable power distribution solution.
