Embodiment Construction

[0018] The present invention will be further described below. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0019] A method for processing a flame-retardant cable, characterized in that it comprises the steps of:

[0020] 1) Mix each component into a pre-mixer at 80-120°C and mix evenly, transfer to a high-speed mixer and stir for 10-15 minutes, and finally extrude and granulate to obtain a flame-retardant cable material, which is carried out according to a certain length Cut into small pieces; the components include 100 parts of PP; 30-80 parts of PVC; 40-60 parts of LDPE; 10-20 parts of plasticizer; 3-8 parts of antioxidant; -45 servings. Specifically, the stirring speed of the high-speed mixer is 400-800rpm. Extrusion granulation is carried out in a twin-screw extruder, and the extrusion temperature is 180-220°C.

[0021] 2) Coating the sm...

Abstract

The invention discloses a flame-retardant cable processing method, and the method is characterized in that the method comprises the following steps: 1) drawing a metal conductor into a metal wire at ahigh temperature, and cutting the metal wire according to a certain length to obtain metal wire sections; 2) coating the periphery of the metal wire sections with an insulating layer to obtain insulating metal wires; 3) coating the insulating metal wires with an adhesive, bonding a plurality of insulating metal wires into a group, and wrapping a protective layer; 4) wrapping the outer side of each section of protective layer with a damping layer; 5) arranging an amplitude controller and an alarm device on each section of the damping layer; 6) connecting each section of the cable through a cable connector. The invention has the beneficial effects that the metal wire manufactured through the manufacturing method is uniform and high in quality, and meanwhile, the amplitude controller and thealarm device are arranged, so that the phenomenon that the cable is stolen can be effectively prevented. And a sectional cable connection mode is adopted, so that the maintenance efficiency can be greatly improved, the damaged cable can be conveniently replaced, and the maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to a flame-retardant cable processing method, which belongs to the technical field of cable production. Background technique [0002] Cable is a wire product used to transmit electric energy. It is the main carrier of electric power transmission and is widely used in many fields such as lighting, home appliances, and industry. In order to ensure safety, there are particularly strict requirements on the flame retardancy of cables, which is a key research topic in the industry. The production process of flame-retardant cables is mostly manual, so that the thickness of wires and cables produced by this method is different, and the standard cannot be unified, resulting in a low pass rate and a waste of manpower and material resources. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a method for processing flame-retardant cables. The wires and ...
