Description
Technical field
The utility model relates to cable technology, particularly relates to a kind of inorganic mineral list core fireproof cable.
Background technology
Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.
The common sheath single-core power cables of existing market can not meet instructions for use at some special occasions, and structure comparison is single, and function is also fewer.And unreasonable owing to arranging between conductor in some common sheath multicore cables, can have an impact each other, the effects such as shielding are bad, and result of use is undesirable, can only reach fire resistance rating, do not reach fire-protection rating.
Utility model content
The purpose of this utility model is, for above-mentioned existing single-core cable function singleness, existing multicore cable does not reach the problem of fire-protection rating, proposes a kind of inorganic mineral list core fireproof cable, and this inorganic mineral list core fireproof cable electric property is superior, fire protecting performance is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of inorganic mineral list core fireproof cable, comprise oxygen-free copper conductor, outside described oxygen-free copper conductor, from-inner-to-outer is coated with inorganic mineral insulation band, Ceramic silicon rubber, copper sheath and halogen-free and low-smoke flame-retardant polyolefin sheathed successively.
Further, described oxygen-free copper conductor is the stranded cross section of stranded copper wire is circular conductor.
Further, described inorganic mineral insulation band is fluorophlogopite belt (also claiming two-sided synthetic mica tape).
Further, described copper wire is the red copper that purity is greater than 99.98%.
The utility model inorganic mineral list core fireproof cable is simple and reasonable for structure, compact, has the following advantages compared with prior art:
(1) electric property is superior, and copper sheath can play shielding action, can put into same crane span structure, to other circuit without electromagnetic interference with order wire.
(2) fail safe is good, and this inorganic mineral list core fireproof cable is smokelessly nontoxic when burning, and do not have secondary pollution, fire protecting performance is high, and can burn 180 minutes well-tended appearances in the big fire of 950 degrees Celsius, normal power-up.
(3) economy, the utility model inorganic mineral list core fireproof cable has lacked a lot of joint compared with existing BTTZ fireproof cable, and it is convenient to lay, and lays the cost of labor eliminated.The utility model copper sheath can make PE line and eliminate a conductor, has saved great amount of cost.
(4) the utility model inorganic mineral list core fireproof cable also solves existing multicore fireproof cable and there is the constant problem of heavy in section production, sabot, transport, construction.
To sum up, the utility model inorganic mineral list core fireproof cable structure is simple, cable good stability, and fire prevention, anticorrosive property are good, and conductivity is high, and creep-resistant property is good, and pliability is strong.
Accompanying drawing explanation
Fig. 1 is the utility model inorganic mineral list core fireproof cable schematic cross-section.
Embodiment
Below in conjunction with embodiment, the utility model is further illustrated:
Embodiment 1
Fig. 1 is the utility model inorganic mineral list core fireproof cable schematic cross-section.
Present embodiment discloses a kind of inorganic mineral list core fireproof cable, as shown in Figure 1, comprise oxygen-free copper conductor 1, oxygen-free copper conductor 1 is the stranded cross section of stranded copper wire be circular conductor copper wire is the red copper that purity is greater than 99.98%.
Oxygen-free copper conductor 1 is outer is coated with inorganic mineral insulation band 2, Ceramic silicon rubber 3, copper sheath 4 and halogen-free and low-smoke flame-retardant polyolefin sheathed 5 from inside to outside successively.Inorganic mineral insulation band is fluorophlogopite belt (also claims two-sided synthetic mica tape, or two-sided composite mica tape).The common composite mica tape of described fluorophlogopite belt Thickness Ratio is thinner, and insulation property and tensile property are all good than common composite mica tape, and the fireproof cable adopting it to prepare, can also be cost-saving while reinforced insulation performance.
Wherein oxygen-free copper conductor 1 is conductor layer, single core oxygen-free copper conductor electrical superior performance, and conductivity is high; Inorganic mineral insulation band 2 and Ceramic silicon rubber 3 constitute insulating barrier; Copper sheath 4 and halogen-free and low-smoke flame-retardant polyolefin sheathed 5 constitutes protection jacket layer, have fire prevention thermal stability high, corrosion resistance and good, shield effectiveness good while also there is splendid creep-resistant property and pliability.
The inorganic mineral list core fireproof cable electric property that the present embodiment provides is superior, and copper sheath 4 can play shielding action, can put into same crane span structure, to other circuit without electromagnetic interference with order wire.Fail safe is good, and this inorganic mineral list core fireproof cable is smokelessly nontoxic when burning, and just can not give birth to secondary pollution, fire protecting performance is high, and can burn 180 minutes well-tended appearances in the big fire of 950 degrees Celsius, normal power-up.Economy is good, and the inorganic mineral list core fireproof cable that the present embodiment provides has lacked a lot of joint compared with existing BTTZ fireproof cable, and it is convenient to lay, and lays the cost of labor eliminated.Copper sheath can make PE line and eliminate a conductor and saved great amount of cost.
The utility model is not limited to the inorganic mineral list core fireproof cable described in above-described embodiment, and the change of the wherein change of oxygen-free copper conductor structure, each layer thickness is all within protection range of the present utility model.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
