Baoding wire factory national standard wire

Baoding National Standard Wire and Cable Sales Center reminds you how to distinguish national standard and non-standard wires and cables. You must choose national standard wires for wires. So how to distinguish national standard and non-standard wires and cables?
It is recommended that you take a look, try twice, and weigh three times. Weight, four price comparisons, five copper quality inspections, six quality inspections, and six tricks will give you the answer.
First look: Check whether the wire and cable products have a quality system certification, check whether the certificate is standardized, check whether there is a factory name, factory address, inspection seal, production date, and whether there are trademarks, specifications, voltages, etc. printed on the wires. It also depends on the cross-section of the copper core of the wire. The high-quality copper is bright and soft in color, otherwise it is a defective product.
Test 2: You can take a piece of wire and bend it repeatedly with your hands. If it feels soft, has good fatigue resistance, has high plastic or rubber feel and has no cracks on the wire insulator, it is a high-quality product.
Three weights: Good quality wires and cables generally weigh within the specified weight range. For example, the commonly used plastic insulated single-strand copper core wire with a cross-sectional area of . wait. Poor quality wires have insufficient weight or insufficient length or too much impurities in the copper core of the wire. If it is a cable, especially a large-sized cable, the easiest way to weigh it is to best reflect whether the copper content of the cable meets the standard and whether the conductor cross-section meets the standard. Generally, you can steal copper to make a small-section cable. If the copper content of the cable passes Weighing that does not meet the weight range of the allowable error stipulated by the state can basically be regarded as non-standard.
Four price comparisons: Due to the low production cost of fake and shoddy wires, vendors often use the guise of low price and high quality to sell them at low prices to deceive people. Therefore, when purchasing, be careful not to be dazzled by the high quality and low price advertised by the merchants and end up being deceived. Five, look at the copper quality. The copper core of qualified copper core wires should be purple-red, shiny, and soft to the touch.
5. Look at the copper core of fake and inferior copper core wires. The copper core is purplish black, yellowish or white, with many impurities. It has poor mechanical strength and poor toughness. It will break with a little force and there are often disconnections in the wires. During the inspection, you only need to peel off one end of the wire and rub it on the copper core with a piece of white paper. If there is black substance on the white paper, it means there are more impurities in the copper core, and it can be identified as non-standard wire and cable.
Sixth quality inspection: If there are differences in cable quality, it can be sent to a third-party testing agency for testing. Based on whether the authoritative test report is qualified.
