How to select qualified cables

1、 Product label

Regular products will clearly and detailedly mark the product parameter information and product related certification. Pay attention to whether there is a quality system certification; Check whether the certificate of conformity is standardized; The wires, cables and wires produced by regular manufacturers have handwriting marks, which are clear and not easy to be scratched off, and the products are provided with a certificate of conformity, which includes 3C certification mark, certification number, model and specification, executive standard, rated voltage, wire length, production date, manufacturer, inspector, factory name, address, fixed telephone, anti-counterfeiting mark, etc.

2、 Insulation material

The insulating materials of high-quality wires and cables have certain strength, flame retardancy and flexibility, which are not easy to tear apart and have high ignition point. The insulation layer of inferior wires and cables can be easily removed by hand, and the ignition point is low during the combustion test.

3、 Conductor material

It is easy to distinguish from the conductor material. The conductor core of the national standard power line is basically made of oxygen free copper. The power line made of oxygen free copper has small resistance, stable transmission, oxidation resistance and long service life. The conductor materials of non-standard power lines are mostly all copper or copper-clad aluminum, of which all copper is also known as bronze and secondary recycled copper. This kind of copper contains many impurities and high resistance, but its oxidation resistance is not much affected; However, the copper-clad aluminum material has low oxidation resistance and is not suitable for long-term use. It also depends on the cross section of the copper core of the wire. The superior red copper has bright color and soft color, otherwise it is a non-standard wire.

4、 Length

The conventional power cord is 100M / roll, and can also be customized according to customer requirements. The national standard power line is full meters, and the difference will not exceed about 0.5 meters; However, the non-standard power line is generally less than 100 meters, and it is normal to have a difference of 8-10 meters, so the actual length can be determined by measuring the number of meters. We can also view it through the meter mark on the thread body, which is also convenient for customers to measure and cut.
