Zhaoqing has sold six cable AMP AMP six four pairs of unshielded

Zhaoqing has sold six cable AMP AMP six unshielded four pairs' AMP cable true and false identification of conductor material market check the network cable network cable a lot, there are many types of conductive material with copper, copper clad aluminum and copper clad steel, copper coated iron, a good oxygen-free copper cable conductors are made, the price difference a lot, take the scissors from the line Xinxie angle cut down, look inside whether it contains impurities or other metallic color , copper network cable generally only in the surface coated with a layer of copper, so that you can save a lot of costs, but will result in a speed and life lines to transmit information. Test the network cable flammability general material network cable must require anti-flammability, what otherwise appears a fire, then it losses a. So everyone in the choice of cable, be sure to check the cable jacket can burn, so as to identify the authenticity. In the specific test, we can first use scissors to cut about 2 cm cable jacket length, and then facing with a lighter skin burn, the skin will be genuine cable barbecue under the fireworks, gradually melt deformation, but certainly not their own skin burn up; if found cable sheath can not help the test of fire, a little on the burn, then the transmission speed of cable no matter how high it should abandon choice, after such a network cable in the wiring project is very safe, the use of it will stay Under great security risk. I once got some genuine cable and inferior cable, while lit with a lighter they found that 6 seconds, the genuine cable is white smoke and, over time, gradually melt deformation, while the inferior cable less than 2 seconds, It is easily ignited, and accompanied by a large number of black smoke.
