Purchasing Guide

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

  • For procurement requirements that require the use of other insulation materials, it is recommended to prioritize checking key technical parameters such as temperature resistance level and dielectric strength to ensure compatibility with the equipment operating environment. For example, high-voltage electrical equipment should pay attention to the partial discharge performance of materials.
  • In different application scenarios such as industrial motors and transformer windings, the thickness and flexibility of other insulation materials can affect the installation process. When purchasing, suppliers can be required to provide performance test reports under typical operating conditions.
  • 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 material batch consistency.
  • For the insulation requirements of photovoltaic backboards or energy storage systems in the field of new energy, it is recommended to conduct a comprehensive evaluation based on the material's weather resistance and flame retardant properties to avoid insulation performance degradation caused by environmental factors.
