How to buy high-quality photovoltaic cables?

For the general public, inferior photovoltaic cable are very harmful, and are likely to cause casualties and fires. In order to obtain the maximum profit, many merchants use inferior raw materials, cut corners on the length and cross-section of photovoltaic lines, and deceive consumers. Although such photovoltaic line products are cheap, the quality cannot be completely guaranteed. Jianzhenda Cable hereby reminds you The quality of photovoltaic lines is very important, don't be greedy for cheap!

Points to note when purchasing photovoltaic cables:

1. Look at the appearance

Smooth and round, uniform in color, the insulating glue of the photovoltaic wire is close to the copper core, and it is not easy to peel off. The inferior glue looks thick, but when squeezed hard, it will turn white, easy to age, and fall off in the future, causing electric shock leakage.

2. It depends on the eccentricity

The thickness of the photovoltaic wire is the same, that is, whether the copper core is in the middle of the wire, and the quality with low eccentricity is better.

3. Verify whether it is flame retardant

When you burn the PV line with a lighter, the insulation of the cable goes out automatically and emits a little white smoke. If the flame spreads and emits a lot of white smoke, the insulation is of poor quality.

4, to see if the quality of copper is pure

Photovoltaic lines are generally made of high-purity copper cores that are anti-aging, highly conductive, false-colored yellow or white. If the copper cores are not pure and there are debris, you can rub a piece of white paper on the copper cores to see if Pure, if there is black material on the white paper, it can only indicate that there are more impurities in the copper core.

5. Pay attention to the label outside

Whether there is a complete quality certificate, CCC mark, rated voltage, length, date, factory name and address, etc.

6. Pay attention to the thickness of the insulating layer

If the photovoltaic line uses inferior copper core, the size specification is often smaller than that of the regular manufacturer, the outer insulating layer is thick, and the diameter error of the line segment cannot exceed 0.02%.

7. Pay attention to the length and size

The length of the photovoltaic line conforms to the international standard of 100±0.5m (that is, 100 meters are used as the standard, and the allowable error is 0.5 meters).

8. Pay attention to the weight of the photovoltaic wire

Generally, the length of each roll of photovoltaic wire is 100 meters, 1.5 square is not less than 1.8 kg, 2.5 square is not less than 2.9 kg, 4 square is not less than 4.3 kg, and 6 square mm is not less than 6 kg.

The products of Jianzhenda Wire and Cable Factory have obtained the honorary titles of ISO9001 certification, 3C certification, ROHS certification, production license, Shenzhen outstanding enterprise, etc. The quality of all wire and cable products meets the requirements of national and industry standards.

Well, the above is the introduction on " How to buy high-quality photovoltaic cables?", I hope it can help everyone! It is recommended to continue to pay attention to JZD Cable to learn more about photovoltaic line information.
