When choosing a cable, consumers usually look at key factors such as the cable's performance, specifications and brand. However, there are often poor quality cables on the market, which brings problems to consumers. Here, we explore an intuitive way to judge the quality of cable - observing the color of the wire core.

Excellent cables, the core is usually made of pure copper, the appearance shines with a dazzling metallic luster, the color is constant and not easy to fade. In contrast, inferior cables, even if the online core material has not experienced any abnormal storage or transportation, often appear dull and lack metal texture.

Why is core color a key factor in determining cable quality?

First, the color of the wire core can reveal the metal used in the cable and its purity. As a common material of cable, copper ensures the stability and reliability of electrical signal transmission with its excellent conductivity. In contrast, inferior cables mostly use aluminum or other alloys with poor electrical conductivity as the core, although the cost is lower, it is easy to lead to signal attenuation and voltage instability and other problems.

Secondly, the instability of the core color may mean that there are impurities or inferior additives in the material, which will destroy the structural stability inside the cable and increase the risk of failure and short circuit. The yellow color of the core may be a sign of aging or poor quality of the material, which in turn affects the life and safety of the cable.

Therefore, when purchasing cables, the color of the core should be carefully checked, and the product with full luster and uniform color is preferred. At the same time, it is recommended to buy brands of cables through regular channels to ensure the quality and performance of cables. Once the core color abnormalities or other problems are observed in practical applications, the use should be stopped immediately, and seek help from relevant people for repair or replacement.

By carefully observing and analyzing the core color, we can effectively identify inferior cables, ensure the power safety of homes and offices, and reduce potential losses and risks caused by cable quality problems.
