What Are The Specifications Of The National Standard Power Cord Plug For Household Use

1. The appearance of the American power cord is clear and clear.

Our country also has standard regulations for electric wires. The name of the manufacturer, the model number and the rated voltage should be clearly marked on the surface. In this way, even in the process of use, problems can occur to find the manufacturer to ensure our rights and safety. Also note that it is consistent with the data on the certificate to prevent the purchase of counterfeit wires.

2. The appearance is smooth, the core is thick

Beyond looking at the logo, you should also pay attention to its appearance. Qualified wires should be smooth and flat, and the insulation and sheath will not be worn out, and the logo and handwriting on the top will be clear, and the hand will feel no greasy feeling. This is the outer part, what should it look like inside? From its horizontal view, its entire round insulation or sheath thickness should be symmetrical and have a certain thickness, and there is no eccentricity.

3. Is the outer plastic plastic insulated?

For the national standard power cord plug, its outer plastic plays a big role. The plastic skin should be chosen to be bright and shiny, and the texture is fine. If you don't know the quality of the outer plastic material, it is best to use a lighter to ignite (you can let the seller cut some wires, pay attention to the fire when you point) to test, if there is no open flame wire, it is good quality.
