Introduction

Key Features

High Efficiency and Low Loss

• Reduced No-Load Losses: The S11 series achieves a significant reduction in no-load losses compared to the S9 series, contributing to energy conservation and cost savings.
• Lower No-Load Current: The no-load current is reduced by 70-85% compared to the S9 series, further enhancing energy efficiency.

Robust Construction and Design

• High-Quality Core Materials: The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, known for their superior magnetic properties. This material choice results in lower core losses and enhanced energy efficiency.
• Fully Sealed Structure: The transformer is fully sealed, preventing the ingress of moisture and contaminants, and extending the service life of the transformer. This design also eliminates the need for an oil storage cabinet, reducing maintenance requirements.
• Advanced Winding Technology: The high and low voltage windings are made of oxygen-free copper, ensuring high conductivity and durability. The low-voltage windings for 500kVA and below use a double-layer cylindrical structure, while those for 630kVA and above use a double-helix or four-helix structure. The high-voltage windings use a multi-layer cylindrical structure, enhancing the transformer's ability to withstand short-circuit forces.

Environmental Compliance

• Eco-Friendly Design: The manufacturing process of the S11 series is aligned with environmental stewardship, using materials and processes that minimize environmental impact and support sustainable development goals.
• Regulatory Adherence: Manufactured in strict compliance with IEC 60076 and GB1094 standards, ensuring that each transformer meets the stringent criteria set by the industry's leading standards for safety, reliability, and performance.
