Setting a New Benchmark for Efficiency: The S11-M Series Fully-Sealed Distribution Transformer, Built for Harsh Outdoor Environments
To help power grids worldwide enhance efficiency and reliability, Mingri Electric Co., Ltd. today officially launches the S11-M Series 10kV Fully-Sealed Distribution Transformers. With a capacity range from 30 to 2500 kVA, this series redefines the standard for outdoor distribution equipment through its exceptional low-loss characteristics, fully sealed maintenance-free construction, and robust environmental resilience.
Product Overview
The S11-M Series Transformers strictly comply with GB standards, featuring no-load losses that are 30% lower than the S9 series, significantly improving operational economy. The corrugated tank wall not only enhances heat dissipation but also increases mechanical strength. Its true core value lies in the "Fully-Sealed" design, which eliminates the risk of insulating oil aging caused by "breathing" in conventional transformers, thereby achieving maintenance-free operation throughout its service life and ensuring stable performance in harsh outdoor environments such as those with dust, moisture, and salt spray.
In the pursuit of grid sustainability, minimizing the total cost of ownership is paramount," said Huang Xing, Director of Power Solutions at Mingri Electric. "The S11-M Fully-Sealed Distribution Transformer is the perfect embodiment of this philosophy. It is not just a product, but a reliable 'deploy and forget' solution. The availability of connection groups like Dyn11 and Yyn0, along with a wide range of voltage tapping options, provides unparalleled flexibility for various complex distribution scenarios.
Key Features
1. High Energy Efficiency:
No-load losses are 30% lower than the S9 series, significantly reducing operating costs.
2. Fully Sealed & Maintenance-Free:
Fully sealed structural design prevents contact between insulating oil and air, eliminating the need for oil replacement throughout its service life.
3. Robust and Durable:
Corrugated tank design provides high mechanical strength, large heat dissipation area, and strong short-circuit withstand capability.
4. Excellent Environmental Adaptability:
High protection rating, equipped with pressure relief valve and gas relay, suitable for outdoor and harsh industrial environments.
Target Applications
● Urban and rural grid upgrades
● Industrial parks, wind farms, solar power plants
● Infrastructure projects (e.g., airports, ports, railways)
● Power distribution systems for commercial buildings
☆ The S11-M Series Fully-Sealed Distribution Transformers are now in production and available for order, including customizations for applications like rectifier or mining duties.
