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
The present invention relates to field of power transmission, particularly to a kind of armouring polyphosphazene insulated cable.
Background technology
Along with development and the raising of electrical equipment and electrical technology of electric cause, high-power electrical, electronic product
The extensive application of sci-tech product of contour performance, one can meet cable use require to have simultaneously fire-retardant
Heat-resisting cable compound seems particularly important.Along with development and the progress of society of science and technology, because of polrvinyl chloride
Harmful with the cable of halogen containing flame-retardant producible smog when burning, cause a lot of people in fire
Member is choked to death, and precision equipment is paralysed, and Halogen CABLE MATERIALS will gradually be eliminated.Thus design and preparation are to people
Harmless, environmental protection, the cable of the fire resistance and insulating properties that simultaneously possess again excellence has important meaning
Justice.
Armored cable is to be contained in the metal canula of insulant by different material conductors, and being processed to can
The solid assembly of bending, armored cable mechanical protection layer may be added on the cable of any structure, to increase
The mechanical strength of cable, improves erosion prevention, is by mechanical damage and the most erodible area for easily
The electric wire of design, such as the directly buried installation for Rock Region.Armored cable is usually to fix and lays electric power
Cable, popular for be just integrally fixed at a place and do not move.And existing power cable fault row
Carry out except needing to be manually entered in buried cable passage, or cable is drawn on earth's surface and investigate, investigation
Efficiency is low, the amount of labour is big, and is difficult to find the particular location of broken string.
Summary of the invention
For this reason, it may be necessary to provide a kind of armouring polyphosphazene insulated cable, it is used for solving when existing cable burns people
Body harm is big, and fire resistance is poor, the technical problem of armoured preform difference.
For achieving the above object, inventor provide a kind of armouring polyphosphazene insulated cable,
Including the protective metal shell of the conductor and outer layer being positioned at cable center, described conductor by two strands with upper conductor group
Becoming, the outer layer of wire is all enclosed with flame-proof heat-resistant insulating barrier, is provided with wire armoring inside described protective metal shell
Layer, the appearance parcel flame-proof heat-resistant insulating barrier of protective metal shell；
Described flame-proof heat-resistant insulating barrier uses polyphosphazene insulating cement to make, and sets between described protective metal shell and conductor
Having packed layer, described packed layer uses aluminium hydroxide to make.
As also having two test leads in protective metal shell described in a kind of preferred structure of the present invention, wherein one survey
Wire is equally spaced along conductor length direction is provided with the first sheet metal in examination, another test lead is provided with
The second sheet metal that described first sheet metal is parallel, is provided with insulation between the first sheet metal and the second sheet metal
Medium.
As a kind of preferred structure of the present invention, described two test leads are arranged on conductor by spiral winding
On.
As a kind of preferred structure of the present invention, described first sheet metal spacing on test lead is 6～10
Rice.
As a kind of preferred structure of the present invention, described dielectric is the oil immersion scraps of paper or potsherd.
As a kind of preferred structure of the present invention, described protective metal shell is metallic copper sheath or the embossing of embossing
Stainless steel sheath, described copper sheath thickness is 0.4～0.8mm, described stainless steel sheath thickness be 0.25～
0.4mm。
As a kind of preferred structure of the present invention, described steel wire armor layer is interwoven by galvanized steel bar silk.
Being different from prior art, technique scheme has the advantage that
1, protective metal shell appearance parcel flame-proof heat-resistant insulating barrier, the outer layer of wire is all enclosed with flame-proof heat-resistant insulation
Layer, packed layer uses aluminium hydroxide, and polyphosphazene insulating cement itself has the electrical insulation properties, heat-resisting of excellence
Property high, advantage that fire resistance is good, and define double shielding；The melting point metal of protective metal shell is high, rises
To useful flameproof effect；The water that aluminium hydroxide burning produces cooperates with flame-proof heat-resistant insulating barrier and hinders
Combustion.
2, equally spaced between two test leads it is provided with the first sheet metal and the second sheet metal, the first sheet metal
And second sheet metal and between dielectric composition capacitor element, therefore when cable generation disconnection fault,
Described test lead also can rupture, and therefore can calculate the tool of broken string according to the capacitance between two test leads
Body position, substantially increases the efficiency of cable break investigation.
3, two test leads are arranged on conductor by spiral winding, it is to avoid cable is the feelings of portion fractures
Condition occurs, is greatly reduced two malfunctioning probability of test lead, as long as which section cable somewhat has on conductor
Just can detect if fracture, improve the accuracy of detection of broken string investigation.
