The SCB series are three-phase dry-type transformers fabricated using epoxy resin vacuum casting technology.
This series represents the mainstream product in dry-type transformers, featuring mature technology, high reliability, and wide application.
It is particularly suitable for power distribution areas with high requirements for safety, environmental protection, and reliability.
• Vacuum casting with epoxy resin: The entire coil is cast and molded, providing high insulation strength, moisture-proof, dust-proof, and corrosion-proof properties.
• High fire resistance level: Flame-retardant and self-extinguishing, non-flammable, meeting the F1 level of fire resistance standards.
• Maintenance-free operation: Oil-free design, no risk of oil leakage, basically maintenance-free.
• Foil-type windings (Type B): The low-voltage windings are made by winding copper or aluminum foil. They have strong anti-short-circuit capability and good heat dissipation performance.
• High mechanical strength: The casting body has high mechanical strength and can withstand the impact of short-circuit electric force.
• Low temperature rise design: The heat dissipation structure is optimized, resulting in uniform temperature rise and long thermal life.
•Low Noise: Optimized magnetic circuit design results in noise levels 10-15 dB lower than the national standard.
•High Overload Capacity: Allows for short-term overload operation (e.g., 150% load for 2 hours).
•Strong Environmental Adaptability: Protection level can reach IP20-IP54, suitable for humid and contaminated environments.
