Technical field
The present invention relates to electric wire field, and in particular to a kind of mineral insulation fire resistant cable.
Background technology
Fire refers to the disaster caused by out of control burning over time and space.In various disasters, fire is
Most frequently, one of major casualty of public security and social development is most generally threatened.
With the continuous development of society, while the wealth of society is increasing, the danger that fire occurs 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, direct property loss caused by fire
Rise to average annual more than ten00000000 yuan.To be 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 main reason for harm are personal,
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.
In order to save more life, property and information from the scene of a fire of mercilessness, it during being applied to of fireproof cable is attached most importance to
Weight, and fireproof cable in the market can be divided into two kinds of rigidity and flexibility by architectural characteristic.Due to rigid mineral insulation electricity
Cable rigidity mineral insulated cable（Mineral Insulated Cable）Abbreviation MI cables are in terms of reliability, production and laying
The defects of, gradually quit listing in European and American developed countries, the main flow cable that flexible mineral insulation fireproof cable turns into fire protection field produces
Product.General cable cover(ing) use copper sheathing, and technique is complex, and efficiency is low, and cost is higher, sheath through frequently with heating temperature compared with

Easily broken core, is not easily broken, and also mitigates the weight of cable；
2nd, the present invention is simple in construction, uses aluminum alloy sheath by inner sheath, not only simplifies technique and improve efficiency, and make
Product cost is declined to a great extent, and cable is unlikely to deform so that the high and low density of cable strength, heat-resisting quantity be good, heat-insulated effect
Fruit is good.
3rd, provided with double-deck mineral insulation, plus inorganic thermal insulation fireprotection layer so that cable has fire-proof insulation from inside to outside
Property, obtain multiple flameproof protection；And formed using Environmental-protective fire-proof nanometer mineral insulation material, can excess load under rated voltage
2.5 times and as usual play insulating effect；Long-term service temperature scope is：- 40 degrees Celsius to 1200 degrees Celsius, insulate as usual；
It is not short-circuit in 1.5 hours under the ablation of 800-1200 degrees Celsius of naked lights, do not trigger electric fire, more will not be combustion-supporting；In naked light ablation
During, not only fire retardant nonflame, and no longer release asphyxia toxic gas, there is low cigarette, nontoxic, Halogen, fire-retardant characteristic；
When bearing mechanical external force, electromagnetism interference；Cost is low, good performance indexes；It is suitable for the insulating barrier of various electric wires.
4th, double-deck mineral insulation is designed using thickness proportion so that insulating properties inside and outside cable coordinates more preferable, reaches
Optimal rank.
5th, fabric hose is extruded outside cable core, presss from both sides cloth（Line）Conveying rubber pipe is by inner glue layer, multilayer folder cloth（Line）Winding layer
Formed with outer glue-line, there is the performance such as high temperature resistant, corrosion-resistant, oil resistant, heat-resisting.
6th, fire resistant sheath is woven into after pipe by alkali-free glass fibre yarn and is coated with organic high temperature-resistant silica gel through high temperature
Reason forms, and has the performances such as fire-retardant, heat-insulated, insulation, anti-electricity, softness, in the case of subzero 54 degrees Celsius its can be maintained flexible
Property, the sustainable work in the case of 260 degrees Celsius, in 550 DEG C of offer reliably protectings, anti-heat wave is resistant to≤1100 DEG C of height in short-term
The impact of warm molten steel.
