Abstract

The invention relates to an armored polyphosphazene insulated cable, comprising a conductor positioned at the center of the cable and a metal sheath at the outer layer, wherein the conductor is composed of more than two wires, the outer layer of each wire is wrapped with an inflame-retarding and heat-resisting insulation layer, a steel wire armor layer is arranged on the inner side of the metal sheath, and the surface of the metal sheath is covered with the inflame-retarding and heat-resisting insulation layer; the inflame-retarding and heat-resisting insulation layers are made of polyphosphazene insulation paste, and a filling layer made of aluminum hydroxide is arranged between the metal sheath and the conductor. Being distinguished from the prior art, the surface of the metal sheath is covered with the inflame-retarding and heat-resisting insulation layer, the outer layers of the conductors are all wrapped with the inflame-retarding and heat-resisting insulation layers, the filling layer is made of aluminum hydroxide, and the polyphosphazene insulation paste has the advantages of excellent electrical insulation performance, high heat resistance and good flame retardation, thus forming a two-layer protection; water generated by the combustion of aluminum hydroxide is mutually matched with the inflame-retarding and heat-resisting insulation layers to retard flame, and thereby the cable is improved in flame retardation and reinforced in environment protection.

Description

technical field [0001] The invention relates to the field of power transmission, in particular to an armored polyphosphazene insulated cable. Background technique [0002] With the development of electrical and electronic business and the improvement of electrical and electrical technology, high-performance electrical and electronic products and other high-performance scientific and technological products are widely used. A cable insulating adhesive that can meet the requirements of cables and has flame retardant and heat resistance appears. extremely important. With the development of science and technology and the progress of society, the smoke produced by the burning of PVC and halogen-containing flame retardant cables is harmful to the human body, causing many people to suffocate and die in the fire, and the precision equipment is paralyzed. Halogen-containing cables will be phased out gradually. Therefore, it is of great significance to design and manufacture cables t...
