This new energy-saving product is developed in the conventional S9/S11-M series, with better short-circuit resistance and safety. It is especially suitable for the users with large fluctuation of power grid and stable voltage requirement. At the same time, it can be automatically (or manually) regulated voltage without interruption of power supply (with load).


Features:

1. The voltage regulation range of transformer is generally designed to be 10±4x2.5%KV, and tapping range can also be designed according to the user's requirements.

2. With the voltage regulation switch, it has a wide range of voltage regulation. It can be automatically (or manually) regulated voltage under the condition of load (without interruption of power supply) and remotely controlled. It can also achieve parallel operation of multiple on load voltage regulating transformers.

Our Advantages:

1. Superior Heat Dissipation and Structural Strength: The spiral coil with longitudinal oil ducts provides excellent heat dissipation, low magnetic leakage, and high mechanical strength. The reliable supporting structure enhances short-circuit withstand capability.

2. Efficient Iron Core: Composed of silicon steel sheets with a thickness of less than 0.35mm and high magnetic conductivity, the core reduces no-load loss and current, improving efficiency.

3. High-Quality Insulation: Materials with high heat resistance withstand overvoltage and overcurrent, ensuring durability and reliability.

4. Superior Transformer Oil: Low viscosity oil with excellent heat transfer and insulation properties protects the core and windings, reducing insulation material aging and extending service life.

5. Durable Oil Tank: Made from high-quality cold-rolled steel plates, treated with de-oiling, rust removal, and phosphating, and coated with three-proof paint, enhancing reliability and reducing maintenance costs.

6. Effective Sealing Rings: Made from high-quality rubber, these rings slow aging, isolate external air, and prevent oil leakage.
