In our daily life, we always see cables. Go along the road and you will always see the cable. It is because of the cable that we can use electricity. Imagine what life would be like if there were no cables to transmit electricity for us. But now, with the development of society and the progress of science and technology, people's living standards have improved. Cables are also in line with international standards, and international cables have emerged. Next, Bian Xiao will introduce the difference between the price of international lines and non-international lines in detail. Let's take a look together.

Second, the difference between national standard cable and non-national standard cable

The national standard line is 100 0.5m/ roll, and some unmarked lines are only 80-95 m/ roll, generally 95 m. The 95th line refers to this 95m unmarked line marked with 100 m.

1? It depends on whether there is a quality system certificate; See if the certificate is standardized; See if there is a factory name, address, inspection stamp and production date; See if there are any trademarks, specifications, voltages, etc. Printed on the wire. It also depends on the cross section of the copper core of the wire. Superior copper is bright and soft, otherwise it is inferior.

2? Want to try. It is recommended to bend the end of the wire repeatedly by hand. All products with soft hand feel, good fatigue strength, elasticity in plastic or rubber, and no crack on conductor insulator are excellent products.

3? Weigh. High quality welding wire is usually within the specified weight range. If the commonly used cross-sectional area is 1.5? Pm2 plastic insulated single copper core wire, per 100? The weight of m is 1.8~ 1.9? kg； 2.5? Pm2 plastic insulated single copper core wire, per 100? The weight of m is 3~3. 1? kg； 4.0? Pm2 plastic insulated single copper core wire, per 100? The weight of m is 4.4~4.6? Kg, wait. The wires with poor quality have insufficient weight or length, or the copper core of the wires has too many impurities.

4? Look at the copper. Qualified copper core wire copper core should be purple, shiny and soft to the touch. False copper core wire is purple-black, yellow or white, with many impurities and poor mechanical strength and toughness. It will break with a little force, often breaking wires. Just peel off one end of the wire when checking? Cm, and then gently rub a piece of white paper on the copper core. If there is a black substance on the white paper, it means that there are many impurities in the copper core. In addition, the insulation of fake and inferior wires seems to be very thick. In fact, most of them are made of recycled plastics. Over time, the insulation layer will age and leak electricity.

5? Look at the price because of the low production cost of fake and shoddy wires, vendors often sell them at low prices under the guise of good quality and low price, which makes people fall for it.

The introduction of GB cable is over here. The above is the GB cable introduced by Bian Xiao. I believe that after reading Bian Xiao's introduction, everyone has a certain understanding of GB cable. When buying a cable, be sure to see if it is an international cable or a non-international cable. Keep your eyes open when shopping. Never buy fake and inferior products. I hope Bian Xiao's introduction can help you and make your life more and more convenient. I hope you can choose the right international line.
