1. Product introduction

The Electrical Distribution Transformers we produce can be used normally in indoor and outdoor power distribution environments. They are currently mainly used in industrial production workshops, power grid systems, commercial buildings, infrastructure projects, and new energy power generation supporting occasions such as wind power and photovoltaic. The equipment relies on special mineral insulating oils for insulation and heat dissipation. The voltage conversion process is stable and reliable, the overall operating efficiency is high, and the short-term overload capacity is strong, which can meet the needs of long-term uninterrupted operation of the project.

2. Product Features

High efficiency and low loss

In the design stage, the impedance, voltage regulation accuracy, and loss values will be reasonably matched to ensure the stable power supply quality and reduce unnecessary power consumption.

Low operating noise

By optimizing the iron core laminating process and the fixed structure of the box, the operating noise is controlled within the standard range, which meets the relevant requirements of IEC, and will not cause interference to the surrounding office and living environment.

Strong short circuit resistance

The winding can be made of copper or aluminum, and it can be used with vacuum dipping or vacuum drying treatment technology. The overall mechanical strength is high and the long-term operating performance is stable.

Factory inspection

Each electrical distribution transformers will complete a full set of electrical tests before leaving the factory to reduce the uncertainty of on-site installation and commissioning, and a complete test report can be provided.

Short-term overload capacity

The oil-immersed heat dissipation structure supports short-term overload operation and can cope with special working conditions such as peak electricity consumption.
