3. Structural Features of SCB10 & SCB11-200KVA/10KV/0.4KV Cast Resin Dry-Type Transformers
Both the SCB10 and SCB11 series 200KVA/10KV/0.4KV transformers from CHH Power share a suite of structural advantages, combining safety, durability, and performance:
(1) Enhanced Safety for Load Center Deployment
CHH Power’s cast resin transformers use fully enclosed epoxy resin casting, eliminating fire risks associated with oil-immersed models. They are non-toxic, pollution-free, and can be directly installed in load centers (e.g., industrial workshops, commercial building basements)—reducing transmission losses and saving installation space.
(2) Robust Mechanical & Electrical Performance
- Advanced Domestic Technology: CHH Power integrates proprietary casting and winding technologies, ensuring high mechanical strength and strong short-circuit resistance (withstands 25kA short-circuit current for 2 seconds).
- Low Partial Discharge: The epoxy resin insulation system minimizes partial discharge (≤10pC at 1.73×rated voltage), enhancing long-term reliability and extending service life to 20+ years.
- Thermal Stability: The transformers maintain stable performance even at high operating temperatures, thanks to heat-resistant materials and optimized winding design.
(3) Energy Efficiency & Low Maintenance
- Low Loss & Noise: Adopting low-loss grain-oriented silicon steel cores and copper windings, the transformers achieve low no-load and load losses—cutting energy consumption by 15% compared to older models. Noise levels are ≤55dB, making them suitable for noise-sensitive environments (e.g., hospitals, residential areas).
- Maintenance-Free Operation: The sealed resin casting protects internal components from dust and moisture, eliminating the need for regular oil changes or insulation maintenance.
(4) Superior Heat Dissipation & Overload Capacity
- Efficient Cooling: Natural air cooling ensures stable operation under rated load. When equipped with forced air cooling (AF), the transformer can handle 120% of rated capacity for short-term peak loads—ideal for grids with fluctuating demand.
- Harsh Environment Adaptability: The resin casting provides excellent moisture resistance (IP23 rating optional), enabling reliable operation in high-humidity, dusty, or corrosive environments (e.g., coastal areas, chemical plants).
(5) Intelligent Temperature Monitoring & Protection
CHH Power offers an optional intelligent temperature control system for both series:
- Automatically detects and displays real-time temperatures of the three-phase windings.
- Triggers fan startup/shutdown based on temperature thresholds (e.g., starts at 100°C, stops at 80°C).
- Includes alarm and tripping functions for over-temperature, ensuring equipment safety and preventing damage.
(6) Compact & Cost-Effective Design
With a small footprint (approximately 1.2m×0.8m×1.5m for the 200KVA model) and lightweight construction, the transformers reduce installation space requirements and lower transportation/installation costs—saving up to 20% on project infrastructure expenses compared to traditional oil-immersed transformers.
CHH Power’s SCB10 and SCB11 series cast resin dry-type transformers balance performance, safety, and cost-effectiveness, making them a preferred choice for modern power distribution networks.
