What are the precautions for selecting electrical cables?

Inspect the CCC certification mark. Wire and cable products are national mandatory safety-certified products. All manufacturers must obtain the CCC certification from the China Compulsory Certification (CCC) Committee, and the CCC certification mark must be present on the certification or the product.

Examine the inspection reports. As products that affect personal and property safety, electrical wires and cables have always been a key focus of supervision and inspection. Regularly inspected by regulatory authorities, legitimate manufacturers must undergo periodic checks. Consequently, suppliers should be able to provide inspection reports from the quality inspection department; otherwise, the quality of the electrical wire and cable products lacks substantiation.

Check the packaging. All companies producing products according to national standards place great importance on product packaging. When making a purchase, pay attention to exquisite packaging, clear printing, complete model and specification details, as well as the factory name and address.

Examine the appearance. Our wire and cable products meet the standard requirements with a smooth, round shape and even coloration. Counterfeit and substandard products have a rough and lackluster appearance. The rubber-insulated flexible cables have a circular shape, with the jacket, insulation, and conductors being difficult to dislodge. Counterfeit and substandard products are rough, with a significant ellipticity, a weak jacket insulation, and can be torn apart by hand.

Examine the conductors. The wires are smooth, and their direct resistance and dimensions meet national standards. Wire and cable products that meet national standards, whether made of aluminum or copper conductors, are quite bright and free of oil stains. Consequently, the direct resistance of the conductors fully complies with national standards, ensuring good conductivity and high safety.

Measure the length of electrical wires and cables. Length is a primary visual method to distinguish between counterfeit and substandard products that meet national standards. Avoid the temptation to seek cheap deals. Choose wires and cables that have actual lengths less than their stated lengths. The length should correspond to the stated meter count. The national standard allows for an error of (+0.5) meters per 100 meters.
