Abstract
The utility model discloses a mineral-insulated metal-sheathed fireproof cable which mainly comprises a conductor, an insulating layer, a lining layer and an outer sheath from inside to outside, wherein the outer sheath adopts a copper strip crimped outer sheath; the insulating layer is formed by winding multiple layers of double-sided mica tapes; the lining layer is made of glass fiber materials; and the conductor is a copper stranded conductor. Because the outer sheath and the insulating layer adopt the structure form, the outer sheath adopts a copper strip crimped outer sheath, and the insulating layer is formed by winding multiple layers of double-sided mica tapes, so that the fireproof performance is greatly improved, and the high temperature resistant performance of the insulating layer and the outer sheath can reach more than 950 DEG C; and in addition, the fireproof cable disclosed by the utility model also has the characteristics of low cost, safety and reliability.
Description
Technical field
The utility model relates to a kind of cable that is used for, and specifically is a kind of fireproof cable.
Background technology
These more than ten years are along with the blowout of comprehensive wiring industry development; The great potential of Chinese market has been seen by the well-known manufacturer in the increasing world; Get into manufacturer such as the Kang Pu of China etc. the earliest, all beautiful had a big fat meat, increasing manufacturer wants that all getting into Chinese market takes a share.Therefore; Along with the low side and the end in sudden huge profits epoch; All big enterprises have all taken out the special skill of controlling oneself, and desire to ask to dominate the market, because market that reaches its maturity has not been to depend the international top-brand popularity alone and introduction of foreign technology just can obtain initiative; More consider how just to catch up with the whole development speed of Chinese comprehensive wiring industry, how could and carry out localized transformation external technology and marketing introducing in the hope of enlarging the market share in China.The most valuable in Network Transmission is the information rather than the network equipment.Information is non-renewable, do not had forever in case just lost also, so people comes backup information through various means by fair means or foul, comes the transmission data through stable network, and they are placed in safe place.People turn to comprehensive wiring system gradually and resist outside invasion and attack and avoid the externally direction of harm, and therefore, the cable fire prevention just becomes its most important thing.
It has often been said that floods and fires have no mercy, since the mankind found fire, fire had not only quickened the development of human civilization, has also brought destruction to human civilization, and the civilization in how many ancient times is destroyed in big fire.Equally, fire also can burn comprehensive wiring system, and Network Transmission is interrupted.Simultaneously, if cable produces a large amount of toxic gases and flue dust in combustion process, can produce influence greatly to personnel's escape so, even become safe hidden danger.Therefore, the engineers of various countries is all studied for data backup and the safer fireproof cable of personnel stepping up.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of the utility model is to provide the mineral insulation metallic sheath that a kind of cost is low, safe and reliable, fire protecting performance is good fireproof cable.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
Mineral insulation metallic sheath fireproof cable, it mainly contains conductor, insulating barrier, inner covering and oversheath from inside to outside and constitutes said oversheath employing copper strips embossing oversheath; Insulating barrier adopts the two-sided mica tape of multilayer to be entwined.
Said inner covering is to be processed by glass fiber material.
Said conductor adopts the copper stranded conductor.
The beneficial effect of the utility model is: because oversheath and insulating barrier adopt above-mentioned version; Make oversheath adopt copper strips embossing oversheath; Make insulating barrier adopt the two-sided mica tape of multilayer to be entwined simultaneously; Improved fire protecting performance greatly, the resistance to elevated temperatures of insulating barrier and oversheath can reach more than 950 ℃; In addition, the utility model also has low, the safe and reliable characteristics of cost.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to specify.
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, conductor; 2, insulating barrier; 3, inner covering; 4, oversheath.
Embodiment
As shown in Figure 1, mineral insulation metallic sheath fireproof cable, it mainly contains conductor 1, insulating barrier 2, inner covering 3 and oversheath 4 from inside to outside and constitutes said oversheath 4 employing copper strips embossing oversheaths; Insulating barrier 2 adopts the two-sided mica tape of multilayer to be entwined.Said inner covering 3 is to be processed by glass fiber material.Said conductor 1 adopts the copper stranded conductor.
The above is the preferred implementation of the utility model, can not limit the interest field of the utility model certainly with this.Should be pointed out that for those skilled in the art, the technical scheme of the utility model is made amendment or is equal to replacement, do not break away from the protection range of the utility model.
Claims (3)
1. mineral insulation metallic sheath fireproof cable, it mainly contains conductor, insulating barrier, inner covering and oversheath from inside to outside and constitutes, and it is characterized in that: said oversheath adopts copper strips embossing oversheath; Insulating barrier adopts the two-sided mica tape of multilayer to be entwined.
2. mineral insulation metallic sheath fireproof cable according to claim 1, it is characterized in that: said inner covering is to be processed by glass fiber material.
