Before purchasing, it is necessary to clarify the specific application environment to match the corresponding product characteristics.
  • When selecting suppliers, priority should be given to product matching, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to balance procurement risks and efficiency.
  • For high-frequency plugging scenarios, it is recommended to pay attention to the contact material and plugging life parameters of the plug, as these details may directly affect long-term usage costs and stability.
