Abstract
The utility model relates to a flame-retardant fire-resistant control cable which is particularly suitable for cables in high-rise building electrical equipment and other occasions and belongs to the technical field of cables for electrical equipment. According to the technical scheme, the flame-retardant fire-resistant control cable comprises copper conductors (1), an insulating layer (2), a high-temperature flame-retardant filling layer (3), a ceramic fireproof and fire-resistant composite strip layer (4) and an outer protective layer (5), wherein the insulating layer is arranged outside each copper conductor; the high-temperature flame-retardant filling layer is arranged among the plurality of copper conductors to form a cable core; and the ceramic fireproof and fire-resistant composite strip layer and the outer protective layer are sequentially arranged outside the cable core. The flame-retardant fire-resistant control cable has the beneficial effects that the cable can be fired into a ceramic armor under the 350-3000 flame or flame-free conditions, the crusting performance is high, and the fireproof and fire-resistant performance is excellent; the cable is high in strength, excellent in mechanical performance, excellent in electric insulating performance, waterproof and moisture-proof; the product price is low, the processing process is easily operated, and the cost can be greatly reduced; and moreover, the flame-retardant property is excellent, the fire resistance level can reach GB12666.6 A-level standard.
Description
Technical field
The utility model relates to a kind of flame-retardant control cable, is specially adapted to the cable that use in place such as high-rise building electrical equipment, belongs to electrical equipment and uses the cable technical field.
Background technology
At present, the fireproof control cable that uses on the market need play fire-resistant effect at the outer wrapped at least 2 layers mica tape of conductor.This kind mode has not only increased cable cost, and the outside diameter of cable also increases very greatly, makes troubles for transportation and installation.
The utility model content
The utility model purpose provides a kind of flame-retardant control cable, and flame-proof environmental protection and fire resistance are good, and be safe, and bending property, tensile property are superior, and long service life solves the problems referred to above that exist in the background technology.
The technical scheme of the utility model is:
A kind of flame-retardant control cable; Comprise copper conductor, insulating barrier, high temperature flame-proof packed layer, the compound belt of potteryization fireproof and outer jacket; The outside of each copper conductor is provided with insulating barrier; Be provided with the high temperature flame-proof packed layer between a plurality of copper conductors, constitute cable core together, the outside of cable core sets gradually compound belt of potteryization fireproof and outer jacket.
Described copper conductor is the soft copper conductor, adopts to meet GB the GB/T3956 central first kind, second type, the 5th type soft copper conductor, and accommodation increases.
Described insulating barrier can make long-time running temperature 90 degree of cable bring up to more than 100 degree for adopting the ultraviolet light irradiation insulating barrier, has prolonged the useful life of cable.
The compound belt of described potteryization fireproof constitutes by the calendering of pottery fireproof silicon rubber and high temperature resistant glass cloth is compound, under 350 ℃ and above flame condition, begins hardening; Reach as high as 3000 ℃, along with temperature raises, hard by the Low fire ceramic shape rapidly, complete housing; The ablation time is long more, and temperature is high more, and is hard more; Hard housing armouring after the burning plays a very good protection to circuit, ensures that circuit is unimpeded under fire condition.
Described outer jacket is the outer jacket that adopts the low-smoke halogen-free polyolefin flame-proof material to process, and has environmental protection function.
The beneficial effect of the utility model is:
1. can be under 350-3000 flame or nonflame condition by Low fire ceramic shape armouring, the crust performance can be good, the fireproof excellent performance;
2. density 1.45-150 is lower than mica tape 25%, and intensity is high, mechanical performance is good, electrical insulation capability is excellent, waterproof, nonhygroscopic;
3. product price is low, and processing technology is simple to operation, and cost can reduce significantly;
4. good springiness own, vertical bag and wrapped compactness and sealing property excellence;
5. fire resistance is excellent, meets the V-0 level, does not come off after the burning;
6. fire resistance rating can reach the A grade standard of GB12666.6, the 90min that promptly in 950 ℃ of-1000 ℃ of flames, burns, and the 3A fuse does not fuse.
Description of drawings
Accompanying drawing 1 is the utility model embodiment sketch map;
Among the figure: the compound belt of copper conductor 1, insulating barrier 2, high temperature flame-proof packed layer 3, potteryization fireproof 4, outer jacket 5.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further through embodiment.
A kind of flame-retardant control cable; Comprise copper conductor 1, insulating barrier 2, high temperature flame-proof packed layer 3, the compound belt 4 of potteryization fireproof and outer jacket 5; The outside of each copper conductor is provided with insulating barrier; Be provided with the high temperature flame-proof packed layer between a plurality of copper conductors, constitute cable core together, the outside of cable core sets gradually compound belt of potteryization fireproof and outer jacket.
Described copper conductor is the soft copper conductor; Described insulating barrier is for adopting the ultraviolet light irradiation insulating barrier; The compound belt of described potteryization fireproof; Be composited by pottery fireproof silicon rubber and the calendering of high temperature resistant glass cloth, described outer jacket is the outer jacket that adopts the low-smoke halogen-free polyolefin flame-proof material to process.
