Product Description

S11 series fully sealed oil-immersed distribution transformers are high-efficiency, low-loss power distribution equipment designed for 6kV, 10kV, 20kV and 35kV power systems. Featuring ultra-low no-load loss, low noise, maintenance-free operation and strong short-circuit resistance, this energy-saving transformer is widely used for residential, commercial, industrial and new energy power distribution projects, fully compliant with IEC international standards.S11 series oil immersed transformers are widely applied in urban and rural power grid renovation, residential communities, commercial buildings, industrial factories, mining enterprises, photovoltaic and wind power distribution stations, road and railway power supply systems. It is the most cost-effective and stable energy-saving power distribution equipment for conventional medium and low voltage power supply projects.

Core Features

- Ultra-low Energy Loss: Adopts advanced step-lap laminated core technology, greatly reduces magnetic leakage and no-load loss, significantly lowers long-term operation power consumption and operating cost.

- Fully Sealed & Maintenance-free: Integrated welded corrugated oil tank, vacuum oil injection process, no oil leakage, no need for regular oil replacement and routine maintenance.

- Strong Operational Stability: High-purity oxygen-free copper windings with tight binding structure, strong short-circuit resistance and anti-deformation ability, stable operation under impact load.

- Low Noise & Low Vibration: Optimized electromagnetic design and core assembly process, effectively suppress operating noise, meeting urban and residential area noise environmental protection standards.

- Flexible Voltage Regulation: Equipped with standard off-circuit tap changer (±2×2.5%) to adapt to different grid voltage fluctuation conditions.

- Excellent Environmental Adaptability: Supports outdoor long-term operation, resistant to high temperature, humidity, dust and altitude changes, suitable for various harsh working conditions.

- Standardized Production: Manufactured in strict accordance with IEC 60076 and GB/T 6451 standards, with stable performance and high safety coefficient.
