Abstract
The utility model relates to a flexible fire-resistant high-rise active power cable, which comprises a plurality of cable cores. The structure of a single cable core is as follows: the cable core contains five kinds of copper conductors; and the periphery of the five kinds of copper conductors is sequentially provided with an inner screen, fire-resistant silicon rubber insulation, an outer screen, a copper shield and a sheath. The plurality of cable cores are closely arranged on the same circumference. The periphery of the cable cores is provided with fan-shaped fillers, in which a plurality of mild steel pipes are arranged. A steel strand is respectively disposed in the middle part of each fan-shaped filler, and the outermost layer of the fan-shaped fillers is intervally coated with fire-resistant silicon rubber ribbons. According to the utility model, the periphery of the five kinds of copper conductors is coated with the fire-resistant silicon rubber insulation so as to play a role in fire-resistant and flame retardant functions, and three steel pipes are respectively added in the fan-shaped filler so as to play a role in a cross-ventilation function and good heat dissipation performance and simultaneously raise carrying capacity. The fire-resistant silicon rubber insulation is coated and overlays outside the outermost layer so as to play a role in a heat-insulation function, make the active power cable satisfy operating requirements and prolong service life of the cable. The flexible fire-resistant high-rise active power cable has good reliability.
Description
Technical field
The utility model relates to cable, the fire-resistant high level active force cable of especially a kind of flexibility.
Background technology
" arteries "---the electric wire of building as modern industry is indelible to the progradation of society.The radiation mode of electric wire is various, mainly based on built on stilts, poling, direct-burried, crane span structure etc.Along with developing rapidly of economic level, the emergence of urban skyscraper, in recent years, the lives and properties heavy losses that the fire in public safety places such as skyscraper, nuclear power station causes have caused the concern of numerous people.Electric wire is one of important channel of initiation fire, and along with the development of economy and urban construction, fire damage is in rising trend, therefore all relatively payes attention to prevention of fires both at home and abroad.What adopt in the skyscraper is the occupation problem that can effectively solve the high-rise inner space, the crane cable that greatly reduces line loss.
Crane cable of the prior art can relate to the problem of mesohigh fire-resistance property difference; and mesohigh fire-resisting cable employing of the prior art is the potteryization fire-resistant silicon rubber; play temperature insulating; but because the self-characteristic of this potteryization fire-resistant silicon rubber: after it is subjected to burning of thermal-flame, can form hard housing, and temperature is more high; housing is more hard; thereby the object that protection is burnt is not damaged, and the heat dispersion variation that this has just caused it causes its ampacity variation.
Disclose a kind of " steel pipe cable " as utility model patent 201220117948, comprised that the insulation cable core, the insulation cable core outside that are positioned at the center are provided with steel wire of internal layer and cover wire, the cover wire outside is provided with steel pipe; Described insulation cable core comprises conduction cable core and insulating barrier, and the conduction cable core is copper wire.The effect that the cover wire outside is provided with steel pipe is to increase the wear-resistant degree of cable, improves the useful life of cable.This structure does not have fire-resistant, resistant to elevated temperatures function, namely is not suitable for the use of crane cable yet.
The utility model content
The applicant does not have fire-resistant effect at steel pipe cable in the above-mentioned existing production technology, and shortcomings such as poor radiation provide a kind of flexibility fire-resistant high level active force cable, thereby make cable play fire-resistant, fire-retardant effect, long service life.
The technical scheme that the utility model adopts is as follows:
The fire-resistant high level active force cable of a kind of flexibility comprises many cable cores, and the structure of unit cable core is: comprise five class copper conductors, in the peripheral order of five class copper conductors interior screen, fire-resistant silicon rubber insulation, outer screen, copper strips are set and shield and sheath; Near arrangement, the cable core outer periphery is equipped with fan-shaped filling, in the described fan-shaped filling many flexible metallic hoses is set on same circumference for many cable cores, and described fan-shaped filling middle part is respectively arranged with steel strand wire, and its outermost layer is enclosed with the fire-resistant silicon rubber band at interval.
As further improvement in the technical proposal:
Three cable cores on same circumference near arrangement;
Three corners of described fan-shaped filling arrange a flexible metallic hose respectively;
The external diameter of described flexible metallic hose is 2mm-5mm.
The beneficial effects of the utility model are as follows:
The utility model has played fire-resistant, fire-retardant effect by in the parcel fire-resistant silicon rubber insulation of the periphery of five class copper conductors, respectively at increasing by three steel pipes in the fan-shaped filling, plays cross-ventilation, effect that thermal diffusivity is good, has improved ampacity simultaneously; At the thicker fire-resistant silicon rubber band of the overlapping wrapped thickness of outermost layer, play heat insulation effect, make the active force cable satisfy instructions for use, prolong its useful life, good reliability.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As depicted in figs. 1 and 2, the flexible fire-resistant high level active force cable of present embodiment, comprise many cable cores, the structure of unit cable core is: comprise five class copper conductors 1, in the peripheral order of five class copper conductors 1 arranges screen 2, fire-resistant silicon rubber insulation 3, outside shield 4, copper strips shielding 5 and sheath 6, fire-resistant silicon rubber insulate and 3 plays fire-resistant, fire-retardant effect; Near arrangement, the cable core outer periphery is equipped with fan-shaped filling 9, in the fan-shaped filling 9 many flexible metallic hoses 7 is set on same circumference for many cable cores, and fan-shaped filling 9 middle parts are respectively arranged with steel strand wire 8, and its outermost layer is enclosed with fire-resistant silicon rubber band 10 at interval.
Near arrangement, three corners of fan-shaped filling 9 arrange a flexible metallic hose 7 respectively to three cable cores of the utility model employing, and the external diameter of flexible metallic hose 7 is 3mm on same circumference.Utilize the principle of thermokinetics, its inside that can make of flexible metallic hose 7 forms cross-ventilation, plays the effect of heat radiation, thereby guarantees ampacity and the fire resistance of active force cable, satisfies its instructions for use.
At outermost layer parcel fire-resistant silicon rubber band 10, play heat insulation effect in addition, make the heat insulation effect of active force cable more obvious.
