Features

Compliance with New Energy Efficiency Standards:

Manufactured in strict accordance with the International Energy Efficiency Class 1 standards. All our S22-M(NX1) series transformers not only meet the new third-level energy efficiency requirements (equivalent to S13 oil-immersed transformer standard) but also reach the first-level energy efficiency level, far exceeding the basic market access standards.

High-Quality Transformer Oil:

Adopting S22 transformer oil, which boasts excellent insulation and heat conduction performance, ensuring stable operation of the transformer even under high load conditions. Meanwhile, it features high cost-performance, helping customers reduce procurement and operation costs.

Outstanding Heat Dissipation & Insulation:

Effectively solves the heat dissipation problem of large-capacity transformers and the insulation challenge of high-voltage transformers, avoiding equipment failure caused by overheating or insulation damage, and improving the overall operational reliability.

Fully Sealed Design:

The transformer adopts a fully sealed structure, which can effectively prevent insulation oxidation, reduce aging speed of internal components, and extend the service life. It also has strong resistance to external environmental interference, suitable for long-term outdoor operation.

High-Efficiency Core Design:

The core is made of high-quality silicon steel sheets with an increased cross-sectional area, which greatly reduces iron loss and improves energy efficiency. Taking the 630KVA model as an example, the S22-M(NX1)-630KVA saves more than 10,000 kilowatt-hours of electricity annually compared with the S13-630KVA model, achieving significant energy-saving effects and reducing long-term operation costs for customers.
