220V to 380V step up 3 phase 100kva dry type transformer

A transformer is an electrical device that is used in AC power distribution systems to safely “step up” or “step down” voltages to meet the incoming power requirements of connected equipment. Transformers achieve this goal without modifying the frequency or amount of electrical power to help ensure connected devices can operate reliably.

There are two primary types of transformers that are defined by the insulation used within the enclosure: dry-type and liquid-filled. 

Unlike their liquid-filled counterparts, dry-type transformers do not incorporate oil, silicone or liquid to dissipate excess heat and meet temperature classification requirements. Instead, the coils within a dry-type transformer are constructed of a gaseous or dry insulation medium.

The dry type transformer is of two types. They are cast resin dry type transformer (CRT) and vacuum pressure impregnated transformer (VPI). On this page, we will explore the basics of Lingfran VPI low voltage dry type transformers and their most common configurations.

Attention Please:

1. Specifications may subject to change without prior notice.

2. Specifications with multiple configurations and transformers are not standardized products, please advise your specific requirements for accurate price. The prices displayed on Alibaba platform are not official, please do not take it as reference.

3. Custom-made service is available, please advise your specific requirements if you do not find the suitable specifications from above form.

4. Three requirements that cannot be met by transformer.

     A) Increase or decrease the incoming or load power.

     B) Change frequency.

     C) Convert single phase to 3 phase.

5. Please use our Variable Voltage and Frequency Converter to change the frequency or transform single phase to 3 phase.

6. Lingfran transformers are normally classified under the following HS Codes.  

8504319000: Rated power not exceeding 1 kVA.
