Check the 3C certification mark and test report (brands such as Bull and Schneider have higher compliance)
Give priority to pure copper wire cores (with better electrical conductivity than copper-clad aluminum)
Youdaoplaceholder0 parameter matches
The length (1m/1.5m/2m) and elbow/straight head are selected according to the equipment requirements
For outdoor use, products with IP protection level should be selected
Youdaoplaceholder0 precautions
