Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a flame-retardant and environment-friendly cable material for network wiring and a preparation method thereof. Background technique [0002] When expansion is required, high-density distribution frames can use space more efficiently by reducing the number of passive distribution frames required in each installation. Most users do not conduct certification tests on the installed network cables, but conduct inspections during the network debugging process. When the network can be connected, the installed cables are considered qualified. This approach is not only wrong but also very dangerous. Because the network traffic is very low during network debugging, the user does not feel any problems at this time. The cable verification test is to test the continuity, length of the cable, and whether the twisted pair connector is connected correctly and other general tests. [00...
