Description
Technical field
The invention belongs to electric wire fields, in particular to a kind of connection of copper core polyvinyl chloride insulation flame-retardant strand type to use
Flexible cable.
Background technology
The evolution of China's fire-resisting cable is rather tortuous, just there is arguement since noun, design and relief department by this
Class product is named as " fireproof cable ", and manufacturing sector is then named as " fire-resisting cable ", and the complete term of IEC standard should be " in fire
Burn under the conditions of flame and require keep circuit integrality cable ", such noun is too long, in the course of time " fire-resisting cable " at
Term accustomed to using, but " fire resisting " and " fire prevention " battle is unfinished so far, regardless of word, when about flame regulation, burning
Between and circuit is completely equal requires, be only the substantive issue of fire-resisting cable, the simulation test of limitation only relatively, really occurs
Any cable can guarantee safe operation when fire, need use more realistic test method, Shanghai Electrical Cable Research Institute in
Start within 1969 to develop and be used for nuclear reactor inorganic insulation signal detection cable (belonging to instrument cable), manufactures experimently aluminium oxide and oxygen
Change magnesium insulation high-temperature-resistant alloy conductor and jacketed cable, certain performance aluminium oxide more preferably compared with magnesia, but for matching electrical wiring
It says, magnesium oxide insulated is had a surplus enough；The eighties in last century, Shanghai Electrical Cable Research Institute are successfully manufactured experimently and produce magnesium oxide insulated
Cable opens market to domestic magnesia cable, due to copper at home for China-Pilkington glass factory coordinative composition of equipments of shining
Valence problem affects being widely used for magnesia cable, and Mica tape adds plastic insulation fire-resisting cable to emerge rapidly, really right
The impact of magnesia cable is very big, in addition commercial speculation heats up, mica tape insulated flame-resistant cable is voguish in the industry, as long as having
Examining report, it appears that this cable can keep circuit integrality when fire occurs, and not deny high-quality mica tape insulation here
Fire-resisting cable can maintain a period of time in fire, but can maintain on earth how long, it is difficult to there is digital concept expression, besides each factory
Product is very different, encounters that the thought that the product of inferior quality is then entertained imaginary or groundless fears is also reasonable, and the fire damage in the big or middle city in China has been drawn
It plays government to pay attention to, a kind of cable with good fire resistance property of research and development becomes those skilled in the art's technology urgently to be resolved hurrily and asks
Topic.
Invention content
The object of the present invention is to provide a kind of copper core polyvinyl chloride insulation flame-retardant strand type connection flexible cables.
A kind of copper core polyvinyl chloride insulation flame-retardant strand type connection flexible cable of the present invention, including copper core,

Two layers of cured phenolic coating composition.
The beneficial effects of the present invention are：
1, insulated wire cores use the 6th kind of soft copper stranded conductor and polyvinyl chloride（PVC）Plastic insulation can be such that cable has good
Flexible nature；
2, fill heat conductive silica gel fill-in pad so that cable have flexibility, excellent insulating properties, compressibility, can blind,
The effects that also acting as insulation, damping simultaneously, flat cable itself will easily be compressed deformation, play the role of protection, anti-extrusion；
3, it is equipped with into porcelain type fire retardant polyolefin sheath, it can be in flame low temperature（400 DEG C or so）It crusts, is formed stable at porcelain
It is whole, oxygen is blocked to inside and outside realization；This product can be by A class fire retardancy tests, and flame retardant effect is excellent, high yield rate, special
Not Shi Yongyu skyscraper, oil field, power station, power plant, mine, chemical industry, subway etc. require the higher occasion of fire-retardant condition, have simultaneously
Standby stronger mechanical performance, such as shock resistance, strong environmental adaptability, this product green, security performance are superior；
4, the present invention uses flame-resistant insulation adhesive tape with simple in structure, electrical insulation properties are good, flame retardant property is good, use
Long lifespan, it is sturdy and durable the advantages that, have extensive market prospects；
5, glass fibre composite fire-proof layer has heatproof height, no using glass fibre mat as substrate compared with organic fiber
The features such as combustion, anti-corruption is heat-insulated, and tensile strength is high, and electrical insulating property is good, and can recycle, environmental protection can play open fire anti-
Fiery flame retardant effect, can be 600 DEG C~1000 DEG C with flame resistant, while having both heat-insulating property, the Flameproof composite material safety collar
It protects, without any toxic.
6, equipped with being combined equipped with phosphating steel wire in psp steel bands and oversheath so that the structure of cable is more firm, is not easy
Deformation, while ground connection or Anti-Jamming can also be played.
