Abstract
The utility model discloses a novel composite fire-resisting cable. The cable is formed through the following manners that: each conductor is wrapped with a ceramic silicone rubber composite tape; and a mica tape is arranged between the ceramic silicone rubber composite tape and each conductor in a wrapping manner. By means of the above manner, the cable can be under double-layer fire-resisting protection. When being burned by fire, the cable can be protected by two kinds of strong fire-resisting materials. When being burned by fire, the outer-layer silicone rubber tape can form a sealed ceramic tube which can isolate flames and spraying water, such that the inner-layer mica tape can be protected from being damaged. Even if the silicone rubber ceramic tube is broken, the inner-layer mica tape can still play an excellent role in fire-resisting protection. With the wrapping ceramic silicone rubber composite tape structure adopted, the diameter of the cable will not be increased, and the cable is of high flexibility in normal use, and materials can be saved; when the cable is processed, special extrusion equipment is not needed; the ceramic silicone rubber composite tape is wrapped inside an outer protective jacket, such that the surface properties of the cable is not affected at all; if the cable has been burnt for more than 120min under 950+50 DEG C, and then is sprayed by water for 3min immediately, the cable can still work normally.
Description
Technical field
The utility model relates to power cable, especially a kind of NEW TYPE OF COMPOSITE fire-resisting cable.
Background technology
The fire-resistant wire and cable field of employment is the higher occasions of fire protection requirement such as various skyscraper facilities, commercial center, information network center (computer controlling center), large warehoused center, naval vessel, oil platform, subway, hospital, metallurgy, chemical industry, fire alarm system and aircraft control system, substitute the plain edition cable with fire-resistant wire and cable gradually both at home and abroad, especially external, fire-resistant wire and cable is in very great demand.Fire-resisting cable commonly used is two kinds, and a kind of is the mineral insulation fire-resisting cable, and this type of higher grade of fire-resisting cable, but the equipment investment that cable is made is high, repay littlely, manufacture difficulty is large, and drum length of cable is restricted, the hard crooked difficulty of cable, cable cost is very high, and producing and selling are restricted.Another kind of is Mica tape fire-resisting cable (CN201965977U), this type of cable is most of to stand 750+50 ℃, burning 90min test, rare energy is by 950+50 ℃, burning 90min test, chance water cloud band namely comes off and causes cable short circuit, and work brings very large difficulty to fire rescue at once.CN202275623U discloses a kind of ceramic fire resistant fire-resisting cable, it is ceramic fireproof＝fire-proof silicon rubber that its outer protective sleeve adopts material, it is ablated through 90 ~ 180min or above time in 650 ~ 1300 ℃ or above flame, silicon rubber is sintered into hard ceramic housing in a short period of time, guarantee that circuit does not open circuit in ablation process, not short circuit, do not prolong combustion, extraordinary anti-flammability is arranged, thereby guarantee that circuit does not cut off the power supply in fire, provide safeguard for escaping and rescuing fire.But outer protective sleeve need to adopt expressing technique, this just needs to be equipped with special-purpose extrusion equipment, and because the bad processing characteristics of ceramic fireproof＝fire-proof silicon rubber, be bound to so that extrude wall thickness can not be enough thin, so just greatly increased processing cost and cost of material.Also be the bad processing characteristics owing to ceramic fireproof＝fire-proof silicon rubber in addition, the bad control of expressing technique, the surface quality of products obtained therefrom is bad.
The utility model content
The purpose of this utility model provides a kind of NEW TYPE OF COMPOSITE fire-resisting cable.
This NEW TYPE OF COMPOSITE fire-resisting cable is wrapped ceramic silicon rubber composite band outside conductor.
In order to strengthen fire-resistant effect, also in order to save cost, the utility model wrapped mica tape also outside ceramic silicon rubber composite band inner wire.
For so that winding effect is better, mica tape and ceramic silicon rubber composite band are preferably twined in the same way.
Lap during Mica tape is 30% ~ 40% of mica tape width.
Lap when ceramic silicon rubber composite band is wrapped is 15% ~ 20% of ceramic silicon rubber composite band width.
The thickness of the ceramic silicon rubber composite band that the utility model uses is 0.08 ~ 0.3mm.Be preferably 0.1 ~ 0.2mm.
In the NEW TYPE OF COMPOSITE fire-resisting cable of the present utility model, the outer wrapped ceramic silicon rubber composite band of conductor is met the fire burning can form a sealing earthenware, can cut off flare and spray quinoline water, guarantee that such cable can be at 950+50 ℃, above and the 3min that sprays water of burning 120min still can work at once, cable still can keep the circuit integrality in burned flame when breaking out of fire in other words, guarantee that electric equipment normally moves, fire-fighting equipment and facility can be worked, thereby guaranteeing that disaster-stricken people can have time enough to flee the scene, to avoid or to reduce loss of life or personal injury and property loss.
The ceramic silicon rubber composite band of wrapped thin softness, rather than be extruded as protecting pipe, cable size can not increased greatly, very soft when normally using, and save material.Adding does not need to be equipped with special-purpose extrusion equipment man-hour, can use same equipment with wrapped mica tape.In addition, within the wrapped externally sheath of ceramic silicon rubber composite band of thin softness, do not affect the surface property of cable fully yet, avoided bad this defective of processing characteristics of ceramic silicon rubber.
Ceramic silicon rubber composite band is combined with mica tape; has double-deck refractory protection; there are two kinds of high refractory materials to protect when meeting the fire burning; outer fire-resistant silicon rubber band is met the fire burning can form a sealing earthenware; can cut off flare and spray quinoline water; protection internal layer mica tape is injury-free, and that is afraid of that the silicon rubber earthenware is damaged, and the mica tape of internal layer still can play fine refractory protection effect.And the use of mica tape can also reduce the consumption of ceramic silicon rubber composite band, further reduces cost.In general, be that wrapped one deck refractory material then needs lap is controlled to more than 50% of twining package tape width, as only use in the prior art fire-resisting cable that mica tape makes its lap just need to be at more than 50% of mica tape width when wrapped.Such as method of the present utility model ceramic silicon rubber composite band is combined with mica tape, lap during Mica tape is 30% ~ 40% of mica tape width, and the lap of ceramic silicon rubber composite band when wrapped is 15% ~ 20% of ceramic silicon rubber composite band width.
Description of drawings
Fig. 1 is the structural representation of a kind of form of NEW TYPE OF COMPOSITE fire-resisting cable of the present utility model.
Embodiment
See Fig. 1.Conductor 1 outer wrapped be mica tape 2, wrapped outside mica tape 2 is ceramic silicon rubber composite band 3.Ceramic silicon rubber composite band 3 is twined in the same way with mica tape 2.Insulating sleeve 4 outside wrapped good ceramic silicon rubber composite band 3.
In the above-mentioned process, the lap during Mica tape is 35% of mica tape width, and the lap when ceramic silicon rubber composite band is wrapped is 15% of ceramic silicon rubber composite band width.The thickness of the ceramic silicon rubber composite band of using is 0.14mm.
