Abstract

The utility model discloses a novel copper core copper sheath fireproof power cable, including a cable core, the cable core form by the transposition of many fireproof cable cores, fill pottery vitrification silicon rubber filler strip in cable core space department, directly crowd the copper clad sheath the cable core outside. The utility model discloses high temperature resistant, alkaline -resisting, resistant oil, oxidation resistance agent, corrosion resistance have, light in weight, and the transportation is convenient to the life of cable has been prolonged.

Description

A kind of copper-core copper sheath fire proof power cable

Technical field

The utility model is related to electric wire field, and in particular to a kind of copper-core copper sheath fire proof 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 copper-core copper sheath fire proof power cable.

For achieving the above object, the utility model provides a kind of copper-core copper sheath fire proof power cable, including cable core, Described cable core is prevented fires by many, and core is stranded to be formed；Ceramic silicon rubber packing is filled in cable core gap, outside cable core Directly extrude copper sheath.

Preferably, described fire prevention core is by pressing copper conductor, be extruded in the Ceramic silicon rubber band that presses outside copper conductor And be extruded in copper strips inner sheath outside Ceramic silicon rubber band and constitute.

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 is filled using Ceramic silicon rubber, nonhygroscopic, it is ensured that electrically Performance, can greatly improve the duration under flame, and inorganic mineral filling is applied in cabling process, improve fire resistance, With fire resistance, blaze up nontoxic smokeless.Ceramic silicon rubber band is provided with insulated wire cores so that core has fine Fire resistance and insulating properties；Inside and outside employing copper strips so that cable has high temperature resistant, alkaline-resisting, oil resistant, antioxidant, corrosion resistant Corrosion, it is nontoxic；Outer layer directly extrudes copper strips so that the simple structure of cable, reduces production cost.

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 copper-core copper sheath fire proof power cable, including cable core, it is described Cable core by many fire prevention, core is stranded forms；Ceramic silicon rubber packing 4 is filled in cable core gap, outside cable core directly Extrude copper sheath 5.Than the simple structure of existing complicated cable, simple production process, and fire protecting performance are also than complicated cable Good, weight saving, convenient transport is time saving and energy saving.

Wherein, described fire prevention core by press copper conductor 1, be extruded in press fire lagging 2 outside copper conductor and The copper strips inner sheath 3 being extruded in outside fire lagging is constituted.

Described Ceramic silicon rubber band outer surface scribbles pitch, with flameproof effect, can be with rat-and-ant proof.

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.

Claims
