Purchasing Guide

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

  • For procurement requirements that require the use of transformer accessories, it is recommended to prioritize checking key technical parameters such as rated voltage, insulation level, and temperature rise limit to ensure compatibility with existing transformers. In industrial scenarios, special requirements such as dust and corrosion prevention should also be considered.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers can usually provide more stable supply of accessories in the field of power equipment.
  • For high-voltage scenarios such as new energy power plants or rail transit, it is necessary to choose accessories with excellent heat dissipation performance and high mechanical strength, while paying attention to the actual application cases of suppliers in similar projects.
  • When purchasing oil immersed transformer accessories, attention should be paid to sealing and oil corrosion resistance indicators. Urban power grid renovation projects often require high long-term reliability of such accessories.
