Wire and cable is an electrical product used to transmit electricity, national standard cables to transmit information and convert electromagnetic energy. However, when users face different prices of "national standard cables", they do not know how to identify and buy qualified and safe cables. What kind of cable is produced in accordance with national standards? How to identify and distinguish different qualities of cable

What is national standard cable?

The national standard cable is the wire produced in full accordance with the national standard. China has clear provisions on the appearance of the cable, mechanical strength, insulation of the sheath, compressive strength, wire resistance and other aspects, and different categories of cables have different national standards

How to identify national standard cable?

To see if there is a quality system certification; See whether the certificate is standard; See whether there is a factory name, factory address, inspection seal, production date; See if the wire is printed with trademarks, specifications, voltage, etc. National standard cable also depends on the cross section of wire copper core, excellent copper color bright, soft color, otherwise it is defective.

Going to try

It is advisable to bend a wire head repeatedly by hand, and those with soft feel, good fatigue strength, large plastic or rubber feel elasticity and no cracks on the wire insulator are excellent products.

Check the copper quality

Qualified copper wire copper core should be purple, shiny, soft. The shoddy copper core wire is purplish black, yellow or white, many impurities, poor mechanical strength, poor toughness, a little force will break, and the wire is often broken. When checking, just peel off one end of the wire 2cm, and then rub a piece of white paper on the copper core slightly, if there is black material on the white paper, it means that there are more impurities in the copper core. In addition, although the insulation layer of shoddy wire looks very thick, it is actually mostly made of recycled plastic, and over time, the insulation layer will age and leak.

Depend on the price

Fake and shoddy wire production cost is low, often in the guise of low prices for sale, therefore, in the purchase of wire can not be too much pursuit of price, electricity safety is about you and me, the purchase of cable, "Wumart" is the starting point.
