National standard cables are manufactured in strict accordance with international standards, safe and reliable, and have a long service life. Refuse to use "non-standard" wires and cables with substandard production and potential safety hazards.

Why use national standard wire and cable？

Compared with the service life of the national standard cable and the non-standard wire and cable, the service life of the national standard wire and cable is much longer than that of the non-standard wire and cable. Next, we analyze the hidden dangers of non-standard wires and cables from several aspects.

                                                                                    

 1. The insulation of the cable mainly plays the role of preventing leakage and ensuring safety. The insulation layer of non-standard wire and cable does not meet the national standard. If the insulation layer of the wire and cable does not meet the standard, the anti-aging degree is reduced, and the insulator cracking is easy to occur during installation, which makes the live conductor bare and threatens personal and property safety.

2. The purity of the copper wire of non-standard wires and cables cannot meet the established standards of the country, and the copper core conductor only accounts for 70%-80% of the cost of the wire. The country has clear regulations on cable manufacturing: the material used for the copper wire of the wire and cable should be electrolytic copper. However, some enterprises use recycled copper or copper-clad aluminum, copper-clad iron, and copper-clad steel to pretend to be copper in order to reduce total costs and increase profits. The electrical conductivity of these synthetic coppers is very poor, and it is very easy to cause the resistance to exceed the standard, and the service life will be greatly damaged.

3. The cross-sectional area of ​​non-standard wires and cables is not enough, and the wires in question are filled with small ones to reduce the cost by reducing the amount of copper used.

4. The length of non-standard wires and cables is not up to standard, the standard line is 100 meters long, and most of the non-standard lines are about 90 meters. The actual measured length of some wires is less than 50 meters, but the nominal total length is 100 meters.

In addition to the above, non-standard cables still have huge potential safety hazards. Non-standard cables are not competent for the work of national standard cables. If non-standard cables are used as national standard cables, considering the above shortcomings, high-power electrical appliances are often "overloaded". Exceeding the safe current of the cable leads to heating and aging. In addition, the outer insulation of "non-standard" cables does not meet the standard, and the aging resistance is reduced, the outer skin will be easily broken, and the service life will not be very long.

                                              

All cable products of Zhengzhou Jinshui Cable Group are produced in strict accordance with international standards, absolutely guaranteeing the authenticity of the products, and rejecting the existence of all products that cut corners and endanger personal safety. In addition, the wires and cables used in our production and life are a long-term solution. We must adhere to the principle of safety when choosing products, and avoid the worry of frequent replacement and worry in the subsequent use process.
