The identification of wire and cable is ''GB'' or ''non-standard'' only need five steps
Jul 17, 2017

With the development of the industry, wire and cable demand is growing, many manufacturers have seen business opportunities, leading to this wire and cable manufacturers more and more, but also more and more complete, but how do we choose the quality of wire and cable, or how should we distinguish between wire and cable is "GB" or "non-standard"?

A look. To see whether the wire and cable products have a quality system certification, see if the certificate is standard, see if there is no factory name, site, inspection chapter, production date, see whether the wire printed trademarks, specifications, voltage and so on. Also want to see the wire copper core of the cross section, excellent red copper color bright, soft color, otherwise is defective.

Second try. It is preferable to have a wire head repeatedly bent with hands, generally soft, anti-fatigue strength, plastic or rubber feel elastic and wire insulator without cracks, is the excellent product.

Three weigh. Good quality wire and cable, generally every 100m weight within the specified weight range. such as the commonly used cross-sectional area is 1.5MM2 Plastic insulated single strand copper core wire, each 100m weight is 1.8-1.9kg; 2.5MM2 Plastic insulated single copper core line, each 100m weight of 3-3.4.0MM2 Plastic insulated single strand copper core line, each 100m weight of 4.4-4.6kg, etc. Poor quality of the wire is insufficient, either length is not enough, or wire copper core impurities too much.

Four than the price. Because of the low production cost of fake and shoddy wires, traders in sales, often to cheap for the pretence of low-cost sales, people fooled. Therefore, when buying, be careful not to advertise for the merchant "inexpensive" dazzled the mind, finally cheated.

Five look at copper. Qualified copper core wire copper core should be purple red, shiny, soft feel. and shoddy copper core line copper core for purple black, yellow or white, impurities, mechanical strength is poor, toughness is not good, a little force will break, and the wire is often disconnected phenomenon. Check, you just have to peel a piece of wire, and then with a white paper in the copper core rub a little, if there is black material on the white paper, that copper core impurities more, you can be identified as "non-standard" wire and cable.
