[0002] With the laying of new 3G networks, new requirements are put forward for broadband local communication cables; not only that, the power of electromagnetic waves of various frequencies is getting larger and larger, and the structure, cost, and anti-interference ability of local telephone cables are also raised. Therefore, although in 2003 the Ministry of Information Industry issued the communication industry standard YD / T1281-2003 "Copper-core polyolefin insulated aluminum-plastic integrated sheathed communication cable suitable for broadband applications", among which the broadband city The composition and technology of the communication cable have been stipulated, but at present this kind of known city communication cable comprising at least two unit cable cores and outer sheaths in the center can meet the development needs of the current communication cable technology. subject to certain restrictions
