Abstract

The invention discloses a cable foaming layer nitrogen charging control method and system, and the method comprises the steps: obtaining a detection image during the nitrogen charging of a core wire through X-ray flaw detection equipment in real time in the nitrogen charging process of the core wire processing of a cable; recognizing the foaming layer image of the cable in the detection image, calculating the uniformity of the foaming layer image during nitrogen charging, and adjusting the nitrogen charging speed according to the uniformity, so the thickness uniformity of the foaming layer can be moderate by intelligently controlling the nitrogen charging speed and air pressure, the capacitance value of the cable is stable, the transmission bandwidth and the transmission rate of the produced cable are ensured, and the stability of data transmission meets the technical requirements of high-speed transmission and information exchange, so that the produced cable has uniform transmission impedance.

Description

technical field [0001] The disclosure belongs to the technical field of wire and cable and cable technology, and in particular relates to a method and system for controlling nitrogen filling of a cable foam layer. Background technique [0002] During the processing of the core wire of the twisted pair, it is generally necessary to fill the cladding layer of the core wire with an inert gas, such as nitrogen, for foaming to form a foam layer. By using chemically foamed polyolefin material in extrusion The heat and pressure foaming extrusion molding in the machine screw chamber realizes the molding of the foam insulating core wire, but the uneven nitrogen filling speed and insufficient air pressure will cause the actual thickness of the foam layer to be different, resulting in unstable capacitance changes , so that the final cable transmission bandwidth, transmission rate, data transmission stability, etc. are difficult to meet the technical requirements of high-speed transmiss...
