China Compact Epoxy Resin Dry-Type Transformer SCB11 10kV Factory Suppliers for Space-Saving Solutions
⚡ Product Features
Overview
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 parks, commercial complexes, municipal infrastructure, outdoor 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 design reduces contact resistance between conductors, effectively lowering load loss, while optimizing the 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 that enhances mechanical strength and operational stability.
🔴 High-Voltage Coil — Vacuum Epoxy Resin Casting
The high-voltage coil is produced using vacuum epoxy resin casting technology. Conducted in a high-vacuum environment, high-performance epoxy resin is injected into the winding gaps, completely eliminating bubbles, impurities, and moisture. After constant-temperature curing, the coil forms a solid cylindrical structure with extremely high mechanical strength, capable of withstanding electromagnetic forces from short-circuit faults. This results in a very low partial discharge level (≤5 pC), reducing insulation aging and significantly improving operational reliability and service life.
♨ Heat Dissipation & Cooling System
Heat dissipation is optimized through thin-layer epoxy insulation on the coil's inner and outer surfaces. The default cooling method is Air Natural Cooling (AN), offering simplicity and low energy consumption. An optional Air Forced Cooling (AF) system is available for high-load density applications — composed of efficient fans, temperature sensors, and a control module, it activates automatically when temperature thresholds are exceeded, enhancing cooling efficiency by over 30% and ensuring safe operation under peak loads.
🛡 Protective Enclosure
The product is equipped with a 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. The protection level can reach IP23, meeting the needs of various application scenarios.
