如何辨别网线质量的好坏（How to distinguish the quality of network cable）

如何辨别网线质量的好坏（How to distinguish the quality of network cable） 1. Test the extensibility of the skin Taking into account the network cable often needs to bend in the wiring, so many regular manufacturers in the production of network lines to the skin to leave a certain extension, in order to ensure that the network is not damaged when bending. Therefore, when both hands stretched the regular net, they found that the skin was stretched. If the force will be broken wire sheath, or skin under the action of external force, there is a crack phenomenon, it shows that the quality of the network cable problems. 2, check the flexibility of the network The good quality of the cable in the design, considering the convenience of wiring, as far as possible very flexible, no matter how curved is very convenient, and not easily broken. Currently on the market there are many traders in order to obtain high sales profits, in the original quality of cable in pure copper is involved in other cheap metal components, so the cable cost will decrease, but the quality and performance of the cable itself is not the same phenomenon is no longer so soft texture of cable cable, transmission the speed of the network is greatly reduced. If you bend the cable repeatedly during wiring, the copper wire inside the cable may be broken. Of course, if you find the cable is too soft, it should also be noted that it may be fake and shoddy products. 3. Test the flammability of the cable Generally speaking, the material that makes up the wire must be resistant to fire, or if there is a fire, it will be disastrous. Therefore, when you select the network cable, you must check the cable skin flammability, to identify the authenticity. In the test, you can first use scissors to cut the cable sheath of about 2 cm in length, then use the lighter to skin burn, the skin will be genuine cable under the fireworks BBQ, gradually melting deformation, but certainly not their skin burns; if the cable sheath could not resi
