The SCB11 epoxy cast dry-type transformer stands as a beacon of excellence in safety and efficiency. Its flame-retardant and eco-friendly design makes it the perfect choice for direct installation within load centers, offering a pristine and secure environment. This maintenance-free marvel simplifies installation and boasts remarkable moisture-resistant capabilities, ready to operate instantly post-shutdown without the need for drying. Expertly crafted to reduce energy loss, local discharge, and operational noise, it promises quiet and efficient performance. With forced air cooling, it can support up to 120% of rated load, showcasing its robust capabilities. A cutting-edge temperature protection and control system ensures safe, reliable operation, meeting the top domestic standards of reliability.
The temperature control system is an engineering masterpiece, featuring a temperature controller with a PTC temperature-measuring element strategically placed at the top end of the low-voltage winding, the transformer's crucial hot spot. This sophisticated system precisely measures and manages the transformer's temperature. In case of excessive heat due to overload or faults, the controller swiftly issues an alarm and activates a self-tripping mechanism if temperatures exceed safe thresholds. Under forced air cooling, it adeptly regulates the cooling fan activation based on winding temperature.
The temperature display system offers a clear and precise visual of the winding's hot spot temperature during operation. This display integrates seamlessly with the temperature control system, significantly boosting monitoring and management capabilities.
The temperature control and display systems are highly adaptable, allowing installation at various distances from the main transformer body. The adjustable lead wire length of the temperature-measuring element ensures optimal placement for accurate readings.

ShellProtectionDevice
The shell is expertly crafted from high-quality stainless steel or aluminum alloy. Protection grades range from IP20 to IP23. An IP20 housing effectively guards against solid foreign objects larger than 12mm in diameter, ensuring the transformer's safety. An IP23 housing
prevents vertical water drops at angles less than 60°, making it suitable for outdoor operations.
Note: Choosing an IP23 housing significantly boosts cooling efficiency but may impact capacity, reducing it by approximately 5% for smaller units and up to 10% for larger ones.
