Purchasing Guide

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

  • In the actual procurement process of insulation boards, it is recommended to match specific application scenarios based on key technical parameters such as voltage level and temperature resistance range. For example, high-voltage equipment needs to use boards with higher dielectric strength.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to ensure supply stability and compliance.
  • For different application scenarios such as distribution cabinets and transformers, differentiated selection should be made based on the mechanical strength and flame retardant performance of insulation boards to avoid redundant or insufficient performance.
  • In the procurement of insulation boards for long-term use in the industrial field, it is recommended to pay attention to the industry performance and platform statistical information of suppliers to evaluate the reliability of their products in practical applications.
