Description
Overview
The SC(B)11 series represents a high-performance, low-loss solution in dry-type transformer technology. Utilizing Epoxy Resin Vacuum Casting, these transformers are engineered for environments where safety, reliability, and environmental protection are paramount.
Designed for 10kV, 20kV, and 35kV systems, this series is characterized by high mechanical strength, excellent flame retardancy, and minimal partial discharge.
Strategic Applications
This product is specifically engineered for indoor configurations and environments with stringent fire protection requirements, including:
-
Infrastructure: Subways, railway stations, airports, and high-rise buildings.
-
Public Sector: Hospitals, schools, and large-scale commercial centers.
-
Industrial: Power plants, factories, oil fields, and mining enterprises.
-
Residential: Urban residential communities and smart-grid integration.
Key Technical Advantages
-
Superior Fire Safety: The epoxy resin material is self-extinguishing and flame-retardant. It will not release toxic gases or support combustion during a fire.
-
Maintenance-Free: Being a dry-type system, there is no risk of oil leakage, eliminating the need for oil testing and filtration.
-
High Overload Capacity: Excellent thermal stability allows the unit to operate under forced air cooling ($AF$) with a significantly increased temporary load capacity.
-
Environmental Resilience: The cast resin protects the windings against moisture, dust, and corrosive industrial atmospheres.
