Technical Drawing
Key Performance and Safety Assurance
High-Level Insulation Protection
Adopting Class C insulation standard with superior performance. Withstands 2500V/60S voltage tests between primary to secondary, primary to ground, and secondary to ground. Insulation resistance exceeds 100MΩ. 125Hz double voltage induced withstand voltage test meets standards, effectively resisting humid and dusty environments while eliminating electric leakage risks.
Stable Heat Dissipation and Temperature Control
Natural air cooling design requires no additional fans, resulting in low operating noise. Temperature rise strictly controlled below 150℃ even under high-load conditions, maintaining stable winding operation and extending equipment service life.
Reliable Grounding Design
Grounding resistance less than 100mΩ (test current 25A) with full compliance to safety specifications. Enhanced operational safety makes it suitable for densely populated areas and locations with high safety requirements.
Core Product Advantages
- Strong Adaptability: Multi-tap voltage regulation design (2×2.5% FCAN + 6×2.5% FCBN) flexibly adapts to voltage fluctuations in different regions. Output 120V/240V single-phase power accurately matches commercial lighting and industrial single-phase equipment without additional voltage regulation devices.
- Outstanding Durability: Full-aluminum windings combine excellent electrical conductivity with lightweight advantages. Class C insulation provides high temperature resistance and anti-aging properties, reducing maintenance needs and lowering long-term operating costs.
- Safety and Compliance: All safety indicators including withstand voltage, insulation resistance, and grounding performance comply with industry standards. No safety hazards such as electric leakage or overheating, ensuring safe operation in indoor commercial areas and industrial workshops.
Applications
Winley Electric SG-75KVA Three-Phase Dry-Type Transformer is particularly suitable for scenarios with high requirements for power supply stability and safety:
- Small and medium-sized industrial workshops: Providing stable power for single-phase machine tools, welding machines, and electroplating equipment
- Commercial complexes: Supporting single-phase loads including lighting systems, central air conditioners, and elevators
- Data centers: Supplying reliable power for auxiliary facilities such as room lighting and monitoring equipment
- Municipal scenarios: Adapting to single-phase power needs for community power distribution and small public buildings, solving connection problems between three-phase grids and single-phase loads
