Compact Epoxy Resin Dry-Type Transformer SCB11 10kV - Space-Saving Design by China Suppliers and Factory
Product Features
This series of dry-type transformers is engineered with advanced manufacturing technologies and high-quality materials, delivering outstanding operational stability, energy efficiency, and environmental adaptability. It is widely applicable in Industrial ParksCommercial ComplexesOutdoor Substations and similar scenarios, meeting diverse demands across various working conditions.
Low-Voltage Coil Design: The low-voltage coil is wound with High-Purity Copper Foil featuring uniform thickness, a large conductive cross-section, and excellent thermal conductivity. This reduces contact resistance between conductors, effectively lowering load loss while optimizing internal electromagnetic field distribution to prevent local overheating. Following winding, the coil ends undergo high-temperature curing, integrating insulation materials with the conductors to form a robust, integral structure.
High-Voltage Coil — Vacuum Epoxy Resin Casting: Produced using vacuum epoxy resin casting technology in a high-vacuum environment, completely eliminating bubbles, impurities, and moisture. After constant-temperature curing, the coil forms a solid cylindrical structure with extremely high mechanical strength. Achieves a very low partial discharge level of ≤5 pC, significantly improving operational reliability and service life, with high short-circuit and lightning impulse withstand capabilities.
Heat Dissipation & Cooling System: Default cooling method is AN — Air Natural Cooling relying on convection and radiation for simplicity and low energy consumption. For high-load density applications, an optional AF — Air Forced Cooling system can be equipped, composed of efficient fans, temperature sensors, and a control module. The AF system activates automatically when temperature thresholds are exceeded, enhancing cooling efficiency by over 30% and ensuring safe operation under peak loads.
High-Performance Protective Enclosure: Constructed from Stainless Steel or Aluminum Alloy, offering excellent corrosion resistance and mechanical strength. Suitable for harsh environments such as humidity, dust, and outdoor weather conditions. Protection level can reach IP23, meeting the needs of various application scenarios.
