DRY TYPE TRANSFORMER TYPES

Choose the Right Dry Type Transformer Types

Huasheng offers the SCBH & SCB dry-type transformer series. SCB is a Chinese model designation. Your projects should start with the electrical system and installation conditions. Just tell us the specifications you need.

Required Capacity

The required capacity depends on the connected load, demand factor, power factor and future expansion. Correct capacity sizing helps prevent overload.

Input and Output Voltage

Huasheng can produce dry-type transformers for 6kV, 10kV, 20kV, 22kV, 24kV and 35kV systems. The secondary voltage is set to the equipment or distribution network.

Frequency and Vector Group

Confirm vector group, earthing method , and tap range with Huasheng. Ensure your project is smooth.

Core and Winding

Select a CRGO silicon-steel core for standard distribution. If the project requires energy savings, you can choose amorphous-alloy core.

Cooling and Enclosure

AN natural-air cooling has no cooling fan dependency. AF forced-air cooling can provide additional cooling when included in the design. The enclosure is made of insulating material.

Installation Conditions

Tell us the ambient temperature, altitude, humidity, dust level and available ventilation. This helps prevent overheating, enclosure changes and installation delays.

EPOXY CAST RESIN TRANSFORMER OPTIONS

What Goes Into a Cast Resin Dry Type Transformer

A cast resin dry type transformer may look similar to another unit from the outside. The core, conductor, casting quality and cooling system can be different.

Transformer silicon-steel core material

Core Options

CRGO is the common core material for dry type transformers. An amorphous-alloy core provides lower no-load. Select based on project acquisition cost and operating losses.

CRGO Silicon-Steel Core Amorphous-Alloy Core
Transformer copper winding conductor materials

Winding Conductor

Tell supplier you project specification requires copper or permits aluminum. The conductor size must meet the agreed loss, temperature-rise and short-circuit requirements.

Copper Aluminum

DRY TYPE TRANSFORMER DETAILS

Check All Details Before You Order

When you’re ready to place an order with a dry type transformer supplier. Remember to double-check all the details. A lower price may stem from different core materials, conductors, loss values, cooling systems, or testing requirements.

Insulation and Partial Discharge

Confirm the insulation class and partial-discharge limit before production. To guarantee product long-term reliability.

Temperature Rise and Ventilation

Dry transformers depend on air circulation. Need check room temperature, ventilation, clearances and altitude.

Loss and Noise

No-load loss, load loss and sound level affect running costs and the surrounding building.

Documents

Each transformer comes with a complete technical documents. It will records the core, winding, insulation system, cooling setup, and key components.

Dimensions and Connections

Huasheng provides an outline drawing for you to approval. Including size, foundation, terminal positions, cable entry and more details.

DRY TYPE DISTRIBUTION TRANSFORMER APPLICATIONS

Where Dry Type Distribution Transformers Are Used

A dry transformer can be placed close to the electrical load when the building design and safety rules allow it. This may shorten low-voltage cable runs, simplify indoor maintenance and remove the need to manage insulating oil.
