Embodiment Construction
[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
[0033] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0034] Such as figure 1 Shown:
[0035] The invention provides a method for processing a halogen-free, low-smoke, flame-retardant B1 grade cable, which includes the following steps:
[0036] S1 Manufacture of cable core conductors;
[0037] S101 Draw the co...

The invention provides a processing method of a halogen-free low-smoke flame-retardant B1-grade cable, relates to the technical field of cable processing, and solves the technical problems that the halogen-free low-smoke flame-retardant cable is relatively low in percent of pass and difficult to form and process in the production process. The processing method of the halogen-free low-smoke flame-retardant B1-grade cable comprises the following steps: S1, manufacturing a cable core conductor; S2, manufacturing an insulating core; S3, manufacturing a finished cable; S4, manufacturing an oxygen barrier layer; and S5, manufacturing a cable sheath. According to the processing method of the halogen-free low-smoke flame-retardant B1-grade cable, gaps of the cable core are filled with the high-flame-retardant linear filling ropes and the high-flame-retardant glass fiber belts are wrapped in a multi-layer mode, so that the cable is more compact, the protection and insulation effects are improved, and a hard shell can be formed when the cable burns by adopting a ceramic polyolefin extruded oxygen barrier layer; flame or high temperature is prevented from entering the cable to be damaged, normal operation in the cable is guaranteed, and evacuation of personnel in a fire scene is prevented from being affected by a large amount of heat released during combustion.
Description
technical field [0001] The invention relates to the technical field of cable processing, in particular to a method for processing a halogen-free, low-smoke, flame-retardant B1-grade cable. Background technique [0002] The cable is composed of multi-layer coaxial structures, and each layer of the structure has different functions, ensuring the stable transmission of current or electromagnetic waves, light waves, etc. transmitted by the conductor core, and also ensuring the safety of external objects and people. [0003] Often in practical applications, high-rise and ultra-high-rise buildings, large entertainment venues, large-scale industrial and mining, enterprises and underground engineering and other densely populated places, cable laying is very dense, once a fire occurs, the cable will produce a lot of smoke and toxic corrosive This not only hinders fire fighting and evacuation of personnel, but also corrodes instruments and equipment. [0004] With the continuous adva...
