Advanced Low Noise Dry Type Transformer
Key Features & Benefits
High Efficiency & Energy Savings
Utilizes high permeability, low loss quality Cold Rolled Grain Oriented (CRGO) silicon steel and advanced step-lap core construction to minimize no load and load losses, ensuring operational efficiency of over 98%. This translates to lower electricity bills and significantly reduces your Total Cost of Ownership.
| Excellent Low-Noise Design |
Optimized core flux density, step lap stacking, and built in damping mechanisms effectively suppress core magnetostriction and winding vibration. Operating noise can be controlled below 50 dB (measured at 1 meter), making it perfectly suited for noise sensitive environments like hospitals, offices, and residential areas.

Enhanced Safety & Reliability Totally dry type design, requiring no flammable insulating oil, fundamentally eliminating the risk of fire and explosion. Windings are consolidated using Vacuum Pressure Impregnation (VPI), creating a solid, monolithic structure that is resistant to moisture, dust, and corrosion, ensuring long term stability in harsh environments.
Strong Overload Capacity Built with Class F or H insulation systems, it possesses robust short term overload capability. At an ambient temperature of 40°C, it can operate with a 20% overload for 2 hours, providing a valuable emergency buffer for your power supply system.
Eco Friendly & Low Maintenance Requires no insulating oil, eliminating the risk of soil and water contamination from oil leaks. Furthermore, the absence of oil that needs periodic replacement or complex oil handling means daily maintenance is straightforward only basic cleaning and inspections are needed greatly reducing maintenance costs.
Smart Monitoring Interface (Optional) Can be equipped with an intelligent temperature control system that monitors winding temperature in real-time, providing over-temperature alarms and trip protection. It also supports remote communication interfaces for easy integration into building or factory smart management systems, enabling predictive maintenance. |

FAQ
Q: How is the high energy efficiency achieved?
A: The efficiency gains come from premium grain-oriented silicon steel cores and optimized electromagnetic design, which significantly reduce iron losses (no-load) and copper losses (load), validated by Tier-1 energy efficiency certification.
Q: How much electricity can Tier-1 energy efficiency save compared to standard transformers?
A: The SCB18-Nx1 reduces no-load losses by over 30% compared to SCB10 models while maintaining lower load losses than SCB13 units. Based on 8,000 annual operating hours, a 400kVA transformer can achieve annual electricity cost savings of ¥20,000-30,000 (actual savings depend on local electricity rates and load factors).
