Description
Technical field
The present invention relates to electric wire field, and in particular to a kind of inorganic mineral insulation protective metal shell fire-proof and water-proof cable.
Background technology
As industrialization, urbanization process are accelerated, all kinds of fire incidents also frequently occur, and cause the huge of lives and properties
Loss.Also, the raising realized with fire-fighting, developed country must select in a part of electric distribution line according to different purposes
Use fireproof cable.Domestic electrical department also promotes the use of fireproof cable in the skyscraper in city and public place of entertainment.
With continuing to develop for society, while the wealth of society is increasing, the danger for occurring fire is caused also to exist
Increase, the harmfulness of fire is also increasing.According to statistics, China's fire seventies annual loss is less than 2.5 hundred million yuan, the eighties
Fire annual is lost less than 3.2 hundred million yuan.Since the nineties, particularly 1993 year, the direct property loss that fire is caused
Rise to average annual more than ten00000000 yuan.Made an inventory according to Chinese fire protection, national whole year in 2014 is informed of a case fire 39.5 ten thousand, dead 1817 people,
Injured 1493 people, direct property loss is up to 43.9 hundred million yuan.From the point of view of statistics, electrical fire account in fire 36.9%, cause
Economic loss account for 58.6%.Although anoxic, high temperature in fire, flue dust, poisonous gas are the personal main causes of harm,
According to statistical analysis the reason for being caused casualties in fire, smoked due to anthracemia death by suffocation or by other poison gas
The dead typically constitutes from the 40%~50% of the total death toll of fire.
The sheath material of common fireproof cable typically uses polyvinyl chloride or crosslinked polyethylene at present.This cable is due to it
Design feature, refractory temperature is low, and the reliability of fire resisting is not strong.When fire occurs, common fireproof control cable can not ensure line
Road works on, it is difficult to be that the longer time is striven in escape and rescue.In the market has a kind of magnesium oxide fireproof cable, actually makes
During, there is problems with：It is not suitable for mobile occasion first, and once damaged insulating properties can decline rapidly copper pipe, and
Insulating properties can drastically decline under high temperature, therefore should not largely be used in engineering；Secondly, this cable is due to magnesium oxide insulated appearance
The easy moisture absorption, cable longitudinal direction is moistureproof to be required and especially seems important from protective metal shell damage, and termination uses fluid sealant, can serious shadow
Ring service life；Furthermore manufacturing process also limit the factory length of cable, cause joint to increase, the water-proofing treatment of joint is also very
Difficulty, often because joint intakes, causes insulaion resistance unqualified.
" Patent No. 2012204838781 " discloses a kind of metal sheath inorganic mineral insulation flexible fire prevention to Chinese patent
Cable, including copper conductor, inorganic mineral insulation and protective metal shell, the fireproofing of cable effect are very good, but waterproof effect
It is very poor.
The content of the invention
In order to overcome the deficiencies in the prior art, there is provided a kind of good waterproof effect of flameproof effect and good inorganic mineral
Insulated metal sheath fire-proof and water-proof cable.
To achieve the above object, the present invention provides a kind of inorganic mineral insulation protective metal shell fire-proof and water-proof cable, including cable
Core, described cable core is formed by many segment conductor-cores are stranded；Described segment conductor-core is by fan-shaped copper conductor and is extruded in sector
Fan-shaped inorganic mineral insulation layer outside copper conductor is constituted；In the gap factice for filling of cable core；Ceramic silicon rubber is externally provided with cable core
Glue twining package tape, is externally provided with corrugated metal sheath in ceramic silicon rubber twining package tape, poly- isobutyl is externally provided with corrugated metal sheath
Alkene waterproofing membrane.
Preferably, described fan-shaped copper conductor is formed by multiply annealed copper wire is stranded.
Preferably, described corrugated metal sheath is corrugated copper sheath, and the corrugated copper sheath is welded using copper strips
Connect and form, copper strips non junction between unit cable length.
Preferably, the thickness of described fan-shaped inorganic mineral insulation layer is 2-3mm.
Preferably, the thickness of described polyisobutene waterproofing membrane is 0.5-1cm.
Compared with prior art, the beneficial effects of the present invention are：
1st, the present invention is simple in construction, using segment conductor-core, more saves filling area than circular core, has saved packing material.
2nd, the present invention uses Ceramic silicon rubber band, nonhygroscopic, it is ensured that electric property, can greatly improve under flame
Duration, apply inorganic mineral filling in cabling process, improve fire resistance, with fire resistance, blaze up also without
It is malicious smokeless.
3rd, the present invention is simple in construction, using inorganic mineral insulation layer, substantially increases overall fire protecting performance, during burning not
Any pernicious gas is produced, is a kind of environment-friendly and green product, using corrugated metal sheath, water spray and machinery can be effectively born
Hit, and add the overall flexibility of cable, cable uses protective metal shell, it is not necessary to poling, easy for installation, and metal is protected
Good corrosion resistance is covered, overall manufacturing cost is relatively low.
4th, filling uses ointment so that cable has good caking property, plasticity, water proofing property, anti-corrosive properties and durability.
5th, wrapped polyisobutene waterproofing membrane outside cable so that cable has tensile strength high, elasticity and elongation percentage are big, glue
Knot property, water-resistance, water proofing property and the features such as good against weather, can be with colod-application, and service life is longer.
6th, when fire occurs, the sustainable power supply of metal sheath inorganic mineral insulation cable,（Bear 950-1000 DEG C high
Temperature, more than 3 hours）, and water when can bear fire-fighting relief drenches, and come off during fire in building object to protective metal shell without
The mechanical shock of machine mineral insulated cable, evacuation and fire rescue for crowd provide great guarantee.
