Abstract

The invention discloses a magnesium oxide fireproof cable filling line, which comprises a first extruder, a screw mechanism, a cooling mechanism, a scraper, a spraying mechanism, a powder coating mechanism and a second extruder. The screw mechanism has a first motor, a first fixing seat and a spiral tube. The spraying mechanism has a collecting bucket and an annular spraying element. The powder coating mechanism has a powder coating box, a second motor and a powder spreading member. The invention also discloses a magnesium oxide fireproof cable and a filling method of the magnesium oxide fireproof cable filling line. The filling line has a simple structure and a reasonable design. It can coat the first insulating layer of the copper core with magnesium oxide powder, and then coat the second insulating layer, so that the cable has two insulating layers, and an additional layer The magnesium oxide powder fireproof layer strengthens the insulation performance and fireproof performance of the cable.

Description

technical field [0001] The invention relates to the technical field of cable manufacturing, in particular to a magnesium oxide fireproof cable, a filling method and a filling line. Background technique [0002] There are many types of products in the wire and cable industry, and the scope of application is very wide. It involves industries such as electric power, petrochemicals, communications, and manufacturing, and is closely related to various sectors of the national economy. RS cables are known as the "arteries" and "nerves" of the national economy. They are indispensable basic equipment for transmitting information and various signals and realizing electromagnetic energy conversion, and are necessary basic products in the future information society. Especially in fast-growing developing countries like China, the huge demand for infrastructure and supporting facilities is self-evident. [0003] The cable is usually twisted by several or several groups of wires, each gro...
