SC(B)10 series 10~20kV resin insulated dry-type power transformer

Safety-Centric Design Philosophy

The SC(B)10 dry-type transformer is an innovative power distribution solution built around safety and efficiency for harsh and sensitive environments. As a 10~20kV resin insulated dry-type power transformer, it abandons flammable oil and adopts high-performance epoxy resin insulation, earning it the title of fire-safe transformer— perfect for places where fire risks must be minimized. Its design prioritizes the protection of people and equipment, making it a top choice for facilities where power outages or fires could lead to catastrophic consequences.

Rated Voltage: 10kV to 20kV

Rated Capacity: 100kVA to 5000kVA

Connection Group: Yyn0 or Dyn11

Protection Level: IP54

Advantages Over Oil-Filled Transformers

Unlike oil-filled transformers, the SC(B)10 series eliminates the need for oil storage and leakage prevention systems, simplifying installation and reducing environmental hazards. It avoids the risk of oil spills that could contaminate soil or water, aligning with eco-friendly practices. Additionally, its dry-type construction reduces weight and space requirements, making it suitable for indoor installation in compact areas like data centers or hospital basements.

Fire-Safe Encapsulation: Class F (155°C) or Class H (180°C) epoxy resin penetrates winding micro-pores via Vacuum Pressure Gelation (VPG), achieving F1 fire rating (IEC 60726) with zero toxic emissions

Low-Loss Magnetic System: Laser-scribed B23R085 silicon steel core with step-lapped joints reduces no-load losses by 32% vs. GB/T 22072

Advanced Cooling: Axial air ducts + Nomex® insulation enable 150% overload for 60 min (hotspot ΔT≤70K)

Environmental Resilience: IP54 enclosure (optional IP66) with salt-spray tested coatings (ISO 9227 C5-M

Smart Monitoring: Embedded Pt100/Pt1000 sensors track winding temperature, insulation capacitance decay, and harmonic distortion (THDu<3%)
