The VDE certification marks for wires and cables have been registered as trademarks and/or service marks in more than 100 countries. Therefore, the VDE certification mark is protected and cannot be abused. Due to VDE's obligations to the public, the intrinsic value of the VDE certification mark is the same everywhere. Manufacturers in more than 90 countries have obtained the VDE certification mark, which proves the significance of the VDE certification mark to exporters.

Wire and cable products play an extremely important role in the fields of power transmission and energy use, and they also imply potential risks that need to be controlled. For high-voltage and high-energy transmission, the safety and reliability of wires and cables need special attention. In the event of an accident, the user's health and life safety will be immediately threatened, and the manufacturer's good reputation will also be damaged.
Therefore, whether it is a wire and cable manufacturer, wholesaler or retailer, or even a consumer who processes, installs or uses wires and cables. The wire and cable products that have been approved by the VDE Testing and Certification Institute and have obtained the VDE certification mark are the guarantee of safety and quality. "German quality" high-quality testing opens the door for cable products to enter the global terminal market and provides safety guarantees for all parties.

VDE certification of wires and cables:
Test standard: IEC60227, HD21
Ordinary PVC (plastic wire): H03VV series (H03VV-F, H03VVH2-F); H05VV series (H05VV-F, H05VVH2-F); H07VV series
