Double steel wire category 6 network cable elevator cable manufacturers tell you that although the wire is a small piece of building material, it can play a vital role in our lives. Moreover, when purchasing electric wires for home decoration, we must pay attention to its quality. We should not think that it is OK if there is nothing wrong with it. Otherwise, the electric wires of poor quality will not only affect our normal life electricity consumption, but also may have huge safety problems. hidden danger. Whether the quality of the wire passes the key depends on the following points:

1. Look at the appearance, it is smooth and round, the color is uniform, the insulating rubber and the copper core are close and not easy to peel off, and the inferior rubber looks thick, but when squeezed hard, the squeezed place will turn white, and it will be easy to age and fall off in the future, causing leakage.
2. Look at the eccentricity, the thickness of the rubber is the same, that is, whether the copper core is in the middle of the wire, the eccentricity is low.
3. Look at the flame retardant. Use a lighter to burn the rubber. When the lighter leaves the wire, the wire should automatically extinguish and release a small amount of white smoke. The manufacturer of Double steel wire category 6 network cable elevator cable tells you that if the fire spreads and releases a lot of white smoke, it means that the rubber Poor quality.
4. Look at the copper core. The high-purity copper core is anti-aging and has high electrical conductivity. The manufacturer of Double steel wire category 6 network cable elevator cable tells you that the color of the fake and inferior is yellow or white, and there are impurities. You can use a piece of white paper on the copper core. Rub it, if there is black material on the white paper, it means that there are more impurities in the copper core.
5. Look at the logo to see if there is a complete certificate, "CCC" logo, rated voltage, length, date, factory name and address and other complete information.
6. Depending on the thickness, the size of the inferior copper core is often smaller than that of the regular factory, and the outer insulation is thick, and the wire diameter error of the wire section cannot exceed 0.02%.
7. Looking at the length, the length of wire and cable products conforms to the national standard of 100±0.5m (that is, 100 meters are used as the standard, and the allowable error is 0.5 meters).
