Purchasing Guide

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

  • For procurement requirements that require the use of oil immersed transformers, it is recommended to match them based on key technical parameters such as voltage level, capacity, and cooling method, with particular attention to the impact of short-circuit impedance and no-load losses on grid stability.
  • In scenarios such as industrial substations or wind farm substations, the explosion-proof design and environmental adaptability of oil immersed transformers need to be evaluated in conjunction with specific application environments. When installing outdoors, priority should be given to protection level indicators.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers usually provide more stable technical support and after-sales service.
  • When purchasing oil immersed transformers, it is usually necessary to focus on the winding material and insulation oil performance. The fully sealed structure is suitable for high humidity environments, while the open design is easy to maintain but requires regular oil quality testing.
