Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of dry-type isolation transformers, it is recommended to match them based on key technical parameters such as input and output voltage, rated power, and insulation level, especially for medical equipment or laboratory scenarios that require attention to anti-interference performance.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. These suppliers often have more stable supply records in the fields of industrial automation or data centers.
  • Dry type isolation transformers in ship power systems or variable frequency drive applications need to consider temperature rise limits and protection levels. When purchasing, suppliers can be required to provide test reports that comply with IEC standards as technical evidence.
  • Different usage scenarios such as mining machinery or photovoltaic power stations have differentiated requirements for the heat dissipation structure and noise level of transformers. It is recommended to evaluate the applicability of product specifications based on specific environmental conditions.

Knowledge Base

Q

This article analyzes the core differences between dry-type transformers and isolation transformers, from their working principles to application scenarios, helping you easily understand the characteristics and selection points of the two types of transformers.

Q

A three-phase dry-type isolation transformer consists of three independent single-phase dry-type transformers, each phase containing primary and secondary coils and iron cores, and the three single-phase transformers are completely isolated electrically. The iron core is made of high silicon steel sheets stacked with full oblique seams, and the input and output windings are shielded with copper foil, which has good electromagnetic shielding performance, can filter harmonics and avoid current waveform distortion.
