Difference between GB cable and non-standard cable
In the choice of cable to choose according to their own site use of the
cable, not for the sake of cheaper. For the majority of users to more clearly, understand the quality standards of cable and self-judgment GB and non-standard differences. Here's to give you a brief introduction:
GB cable and non-standard cable difference? Cables and cables are generally used in engineering users and construction projects these three kinds of cables appear:
1, GB cable: according to the statement issued by the relevant cable standard cable produced by the abbreviation of the international line.
2, line standard cable: According to industry standards, mainly less jerry-building, but does not affect the large use of performance.
3, non-standard cable: to meet the market demand came into being products. Nowadays, the application of wire and cable is more and more widespread. Along with it, more and more wires and cables are sold on the market.
So, the difference between GB
cable and non-standard cable?
A look: to see the quality of wire and cable products without the system certification to see whether the certificate of conformity, see whether the factory name, site, inspection chapter, the date of production, see the wire is printed with the trademark, specifications, voltage and so on. Also depends on the cross-section of the wire copper core, excellent product copper color light, soft color, otherwise it is defective.
Second test: it is advisable to bend an electric wire head by hand repeatedly. All of them are soft and good in anti-fatigue strength. The plastics or rubber are very elastic and have no cracks on the wire insulator.
Three weighed weight: good quality wire and cable, usually every 100m weight within the specified weight range. In particular, large-scale cables, weighing the soil method is the best way to reflect whether the cable copper content compliance and conductor cross-section is enough standard method, if the copper content of the cable after weighing less than the national allowable error Within the weight range, the basic can be identified as non-standard.
Fourth, the price: Due to the low production costs of fake and shoddy wires, therefore, traders in the sales, often cheap and cheap for sale under the guise of cheap, so people are fooled. Therefore, when buying, beware, do not be advertised for the business "inexpensive" dizzy mind, eventually deceived. Five look copper. Qualified copper wire copper core should be purple, shiny, feel soft.
Fifth, look at copper material: fake copper core copper black purple, yellow or white, impurities, poor mechanical strength, poor toughness, a little effort that will break, and the wire is often broken. Check, you just peel off the wire for a while, and then use a piece of paper on the copper core a little rub, if there is a black material on the white paper, copper impurities more, you can be identified as "non-standard "Wire and Cable.
Six quality testing: In the case of cable quality differences, can be sent to third-party testing agencies for testing. The authority of the test report is based on the eligibility.
A look, the second test, three weighed, four than the price, five to see copper, six quality testing, six strokes see the outcome. Did you learn the trick of resolving wire and cable? If you still want to buy wire and cable, please contact us!
