Product Introduction
The SCB11 epoxy cast dry-type transformer sets a new standard in safety and reliability. Its flame-retardant and non-polluting nature makes it perfect for direct load center installations. Completely maintenance-free, it simplifies the installation process, saving both time and effort. With its outstanding moisture-proof performance, it resumes operations immediately after a shutdown without pre-drying. Designed for low energy loss, minimal local discharge, and quiet operation, the transformer handles up to 120% of its rated load under forced air cooling. Featuring an exceptional temperature protection control system, it ensures safe and reliable operation, aligning with the highest domestic standards.
The temperature control system is a technical marvel, integrating a temperature controller with a PTC temperature-measuring element positioned at the low-voltage winding's top end-the transformer's critical hot spot. This system accurately measures and manages the transformer's temperature. In case of excessive temperatures due to overload or faults, the controller issues an alarm and initiates a self-tripping mechanism if temperatures exceed safe limits. Under forced air cooling, it effectively regulates the activation of the cooling fan based on winding temperature.
The temperature display system provides a clear visual representation of the winding's hot spot temperature during operation. This display can seamlessly integrate with the temperature control system, enhancing monitoring and management capabilities.
The temperature control and display systems are highly adaptable, allowing for installation at varying distances from the main transformer body. The length of the lead wire of the temperature-measuring element is adjustable for optimal placement.
Temperature Control: <20m
Temperature Display: <10 m (two-wire system)
<100m (two-wire system with compensating wire)

ShellProtectionDevice
The shell is crafted from premium stainless steel or aluminum alloy. Protection grades range from IP20 to IP23. An IP20 housing effectively safeguards 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 ideal for outdoor operations.
Note: An IP23 housing significantly boosts cooling efficiency; however, it may reduce the transformer's capacity by around 5% for smaller units and up to 10% for larger units.
