Line mode, bending angle is limited, does not also have anti-extrusion buffering effect.
Summary of the invention
The purpose of the present invention is to provide a kind of flexible inorganic mineral insulated cables, to solve the above technical problems.
To achieve the above object the invention adopts the following technical scheme: a kind of flexible inorganic mineral insulated cable, packet
It includes: PVDF sheath, copper armoured, copper inner armor, minerals refuge floor, PE waterproof layer, copper shielded layer, minerals packet
Band, mineral material filler, mica insulation layer, copper stranded conductor, copper armoured and copper inner armor all have centainly
Radian and elasticity, the circular arc at copper armoured both ends and the annulus at copper inner armor both ends be engaged, form it is flexible copper
Chain armouring, and there is certain anti-extrusion buffering effect, the PVDF sheath is wrapped in the outside of copper chain armouring, mine
Substance refuge floor and PE waterproof layer are successively set on the inside of copper chain armouring from outside to inside, and copper shielded layer setting is anti-in PE
On the inside of water layer, and the ribbon that copper shielded layer is woven by copper wire, the minerals band are arranged on the inside of copper shielded layer, institute
It states copper stranded conductor and shares 5, and outside is wrapped up by mica insulation layer, 5 copper stranded conductor equidistant arrangements are in mineral
On the inside of matter band, and gap is filled using mineral material filler.
On that basis of the above technical scheme, the main material of the PVDF sheath is vinylidene fluoride homopolymer or inclined fluorine second
The copolymer of alkene and other a small amount of fluorine-containing vinyl monomers, it has both the characteristic of fluororesin and resins for universal use, good except having
Chemical corrosion resistance, heat-resisting quantity, oxidative resistance, weatherability, resistance to ray radiation performance, and there is non-ignitable characteristic.
On that basis of the above technical scheme, the copper chain armouring is similar to stainless steel used in bathroom in daily life
Hose for shower head is engaged by copper armoured and copper armoured the two and is formed, and copper armoured and copper inner armor both ends are all provided with
Have and be integrally formed the annulus with opening, two annulus are engaged, and have biggish activity point of view, and with certain in the middle part of the two
Protuberance radian, there is certain anti-extrusion buffering effect.
Compared with prior art, the invention has the following advantages that the present invention is by traditional flexible inorganic mineral-insulated fireproof
The oversheath of cable changes novel PVDF material production into, improves fire prevention and insulating capacity, under lasting baked wheaten cake state, PVDF is not
It can burn and generate poison gas, and traditional armouring is improved, make new armouring that there is preferably flexible and protectiveness,
The service life of cable is improved, the present invention is able to maintain normal working condition continuing in the state of baked wheaten cake.
Detailed description of the invention
Fig. 1 is main view structural scheme of mechanism of the invention.
Fig. 2 is copper chain sheathed structure schematic diagram of the invention.
In figure: PVDF sheath 1, copper armoured 2, copper inner armor 3, minerals refuge floor 4, PE waterproof layer 5, copper screen
Cover layer 6, minerals band 7, mineral material filler 8, mica insulation layer 9, copper stranded conductor 10.
Specific embodiment
The present invention is further elaborated in the following with reference to the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, a kind of flexible inorganic mineral insulated cable, comprising: PVDF sheath 1, copper armoured
2, copper inner armor 3, minerals refuge floor 4, PE waterproof layer 5, copper shielded layer 6, minerals band 7, mineral material filling
Object 8, mica insulation layer 9, copper stranded conductor 10, it is characterised in that: copper armoured 2 and copper inner armor 3 all have centainly
Radian and elasticity, the circular arc at copper armoured 2 both ends and the annulus at copper 3 both ends of inner armor be engaged, form flexible copper
The chain armouring of matter, and there is certain anti-extrusion buffering effect, the PVDF sheath 1 is wrapped in the outer of copper chain armouring
Side, minerals refuge floor 4 and PE waterproof layer 5 are successively set on the inside of copper chain armouring from outside to inside, and copper shielded layer 6 is set
It sets in 5 inside of PE waterproof layer, and the ribbon that copper shielded layer 6 is woven by copper wire, the minerals band 7 are arranged in copper screen
6 inside of layer is covered, the copper stranded conductor 10 shares 5, and outside is wrapped up by mica insulation layer 9,5 copper stranded conductors
10 equidistant arrangements fill gap using mineral material filler 8 in 7 inside of minerals band.
The main material of the PVDF sheath is vinylidene fluoride homopolymer or vinylidene and other contain vinyl fluoride on a small quantity
The copolymer of base monomer, it has both the characteristic of fluororesin and resins for universal use, except with good chemical corrosion resistance, high temperature resistant
Property, oxidative resistance, weatherability, resistance to ray radiation performance, and have non-ignitable characteristic.
The copper chain armouring is similar to stainless steel hose for shower head used in bathroom in daily life, by copper armoured
