Commonly used cables are mainly PVC insulated cables, cross-linked polyethylene insulated cables, overhead insulated cables, rubber insulated power cables, etc. Many of these cables are produced in accordance with national or industry standards, and some are produced according to customer requirements. So, do you know what is the difference between national standard cable and non-standard cable? What are the ways that Tianxing cable tells you to distinguish them?

1. Weigh. Good quality wires are generally within the specified weight range. For example, the commonly used plastic insulated single strand copper core wire with a cross-sectional area of 1.5mm2 weighs 1.8 to 1.9kg per 100m; 2.5mm2 plastic insulated single strand copper core wire, weight of 3~3.1kg per 100m; 4.0mm2 plastic insulated single strand copper core wire, weighing 4.4~4.6kg per 100m. Poor quality wire weight is insufficient, either the length is not enough, or the wire copper core impurities are too much.

2, to see. See whether there is a quality system certificate; 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. Also look at the cross section of the wire copper core, excellent copper color bright, soft color, otherwise it is defective.

3. Look at the copper. 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. Check, you just peel the wire head 2cm, and then use a piece of white paper on the copper core slightly rub, if there is black material on the white paper, indicating that there are more impurities in the copper core.

4. 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.

5. Compare prices. Because of the low production cost of fake and shoddy wires, vendors often sell at low prices under the guise of cheap and good quality, so that people are fooled.
