The utility model discloses high temperature resistant, alkaline -resisting, resistant oil, oxidation resistance agent, corrosion resistance have to the life of cable has been prolonged.
Description
Technical field
The utility model is related to electric wire field, and in particular to a kind of 0.45/0.75kV copper cores copper sheath fire prevention electric power
Cable.
Background technology
Fire refers to disaster over time and space caused by out of control burning.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 is lost less than 2.5 hundred million yuan, the eighties
Fire annual is lost less than 3.2 hundred million yuan.Into the nineties, particularly 1993 year since, the direct property loss that fire is caused
Rise to average annual more than ten00000000 yuan.Make 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 causing casualties in fire, smoke 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 merciless scene of a fire, being applied to of fireproof cable attach most importance in it
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 reliability, in terms of producing and laying
Defect, gradually quit listing in European and American developed countries, flexible mineral insulation fireproof cable become fire protection field main flow cable produce
Product.
Utility model content
In order to overcome the deficiencies in the prior art, there is provided one kind has high temperature resistant, alkaline-resisting, oil resistant, antioxidant, resistance to
Corrosive 0.45/0.75kV copper cores copper sheath fire proof power cable.
For achieving the above object, the utility model provides a kind of 0.45/0.75kV copper cores copper sheath fire proof power cable, bag
Include cable core, described cable core is formed by a pair of insulated wire cores pair twists are stranded；In cable core gap, filling alkali-free glass silk fiber is filled out
Rope is filled, in the outer wrapped two-layer ceramic SiClx rubber strip of cable core, further around bag ceramic after the outer wrapped glass fibre belt of ceramic silicone rubber belt
Silicone rubber belt, is finally externally provided with copper sheath in cable.
Preferably, described insulated wire cores by press copper conductor, be extruded in the insulating barrier pressed outside copper conductor, overlap it is wrapped
Two-sided synthetic mica tape outside insulating barrier and the Ceramic silicon rubber band being extruded in outside two-sided synthetic mica tape are constituted.
Preferably, described Ceramic silicon rubber band outer surface scribbles pitch.
The beneficial effects of the utility model are：
Compared with prior art, the utility model this product adopts multi-layer ceramics SiClx rubber strip, nonhygroscopic, it is ensured that electricity
Gas performance, can greatly improve the duration under flame, and inorganic mineral filling is applied in cabling process, improve anti-flammability
Can, with fire resistance, blaze up also nontoxic smokeless.Mica tape is provided with insulated wire cores, with good fire resistance；
Outermost layer adopts copper sheath so that cable has high temperature resistant, alkaline-resisting, oil resistant, antioxidant, corrosion resistance.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limit scope of the present utility model, after the utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application claims limited range.
As shown in figure 1, the utility model provides a kind of 0.45/0.75kV copper cores copper sheath fire proof power cable, including cable
Core, described cable core is formed by a pair of insulated wire cores pair twists are stranded；Alkali-free glass silk fiber gasket for packing is filled in cable core gap
5, in the outer wrapped two-layer ceramic SiClx rubber strip 4 of cable core, further around the ceramic SiClx of bag after the outer wrapped glass fibre belt 6 of ceramic silicone rubber belt
Rubber strip 4, is finally externally provided with copper sheath 7 in cable.
Wherein, described insulated wire cores by press copper conductor 1, be extruded in the insulating barrier 2 pressed outside copper conductor, overlap it is wrapped
Two-sided synthetic mica tape 3 outside insulating barrier and the Ceramic silicon rubber band 4 being extruded in outside two-sided synthetic mica tape are constituted.
Described Ceramic silicon rubber band outer surface scribbles pitch, with flameproof effect.
The above is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of this area
For member, on the premise of without departing from the utility model principle, some modifications and improvement can also be made, these also should be regarded as category
In protection domain of the present utility model.
