Product Introduction

In 2023, we were thrilled to deliver a top-of-the-line isolation dry type transformer to Shenzhen, China. This transformer boasts a remarkable 630 kVA-0.4/0.4 kV capacity, making it an exceptional addition to any industrial or commercial setting requiring reliable power distribution.The rated power of the dry type transformer is 630 kVA, the primary voltage is 0.4 kV and secondary voltage is also 0.4 kV with delta star connection. The cooling is AN/AF, the connect group is Dyn11. Cast resin technology provides excellent insulation and environmental protection, this together with the foil winding technology inside the resin offers the ultimate dry type transformer in terms of dielectric performance and short circuit withstand ability and ensures long term reliability for both distribution and special applications. Cast resin transformers can be supplied with either aluminum or copper windings together with possibility of class F or class H insulation system, they can be designed to in-door or out-door installation with different enclosures.

We ensure that each one of our delivered units has undergone rigorous full acceptance testing. We provide one-package service from consulting, quoting, manufacturing, installation, commissioning, training to after sale services, our products are now operating in more than 50 counties in the world. We aim to be your most reliable supplier as well as your best partner in business!

630kVA-0.4/0.4kV Transformer Manufacturing Process

Transformer core:

1.Our cores are made of high quality grain oriented silicon steel sheet.

2.Our coils are made of high quality copper.Both High Voltage (HV) and Low Voltage (LV) windings are done using Coil Winding Machines. The Copper or Aluminum strips/wires used in winding are meticulously selected for its quality to give the best output. The Copper or Aluminum strips/wires are paper covered and acts as insulators.

Finished 630kVA-0.4/0.4kV Transformer

The epoxy resin dry type transformer has the characteristics of good electrical performance, strong lightning impact resistance, strong short-circuit resistance, small size, and light weight. The temperature display controller can be installed to display and control the operating temperature of the transformer windings to ensure the normal service life of the transformer.

What is isolation dry type transformer：

Isolation dry type transformers are a critical component in electrical systems. They are designed to provide safe and efficient power transfer, while isolating electrical circuits to prevent unintended shorting or damage to the equipment. These transformers are used in a variety of industries, including commercial, industrial and residential settings, and are an important part of modern infrastructure.

One of the advantages of isolation dry type transformers is that they are completely sealed, which eliminates the need for any external cooling system. This makes them very efficient and reliable, ensuring that they operate optimally for long periods of time. Additionally, they have a low noise level, which is an important consideration in settings where noise can be a distraction or cause discomfort.

Another major advantage of isolation dry type transformers is their ability to operate in harsh environments, such as those with high humidity, dust or corrosive chemicals. This means that they can be used in a wide range of applications, from manufacturing plants to offshore drilling rigs.

Isolation dry type transformers are also designed to be environmentally friendly. As they do not use oil or other hazardous chemicals, they are considered to be more eco-friendly than traditional transformers. This makes them an ideal choice for companies that prioritize sustainability and want to reduce their carbon footprint.

FAQ
