China Energy Efficient Dry Type Transformer for Industrial Power Solutions

GUANGBIAN is a professional Dry Type Transformer manufacturer with more than 20 years of export and production experience in China. We supply both standard and customized transformer solutions for different industries and power systems.

Our production range includes:

Capacity: 10KVA to 5000KVA

High Voltage: 1kV to 72.5kV

Low Voltage: ≤1kV

In addition to standard models, we also manufacture isolation transformers and rectifier transformers for specialized applications.

What Exactly is a Dry Type Transformer?

Unlike oil-filled units, a Dry Type Transformer uses epoxy resin and air for insulation instead of insulating oil. The sealed winding structure improves operational safety, reduces maintenance requirements, and ensures stable performance in indoor environments.

It is widely used in hospitals, schools, commercial buildings, factories, and data centers where fire protection and environmental safety are critical.

Three Types

What forms do GUANGBIAN's Dry Type Transformers usually take indoors?

Here's the breakdown:

1. Open Type

Windings stay exposed to air, no epoxy wrapping. Simple setup, fine for clean dry places. Honestly though, this type isn't common anymore. We maybe get one or two orders for it a year.

2. Cast Resin Type

Compact and widely used in commercial buildings. This is what we ship most often at GUANGBIAN. We take the open structure and cast epoxy resin over the windings and coils. Gives you real insulation. Most of our orders fall into this category.

3. Enclosed Type

Full sealed build. Same cast resin base, plus we add an enclosure around the Dry Type Transformer. Reaches IP43 protection - handles rough conditions without breaking a sweat.

Customization Capabilities

Over the years, Isolation Dry Type Transformers have been really popular with our overseas factory customers.

Customization is where we shine. Here's a case: we did a project in Saudi Arabia for a customer who needed isolation transformers. To make their wiring easier, we put two circuit breakers on the transformer enclosure - one on the input side, one on the output side. Left space for their incoming voltage and outgoing wires. Took care of their wiring headaches completely.
