Abstract

The utility model relates to a vitrified fireproof fire-resistant silicone rubber wire cable. The wire cable includes a plurality of conductors. Vitrified silicon rubber insulating layers are pressingly wrapped at the exteriors of the conductors to form wire cores; a wrapping tape layer is pressingly wrapped around the plurality of wire cores to form a cable core; padding is arranged in the cable core; and a vitrified silicone rubber outer sheath is arranged outside the cable core. Compared with an ordinary rubber cable and an flame-retardant rubber cable, the wire cable of the utility model is advantageous in that: after the wire cable is burned by high-temperature flames, a hard shell body is formed and can protect a burning object from being damaged; the hard shell body which is formed after the wire cable is burned can protect the wire cable, thereby ensuring smoothness of electric power supplying and communication and saving precious time for personnel evacuation and rescue in a fire disaster.

Description

Ceramic fireproof=fire-proof silicone rubber wire cable
Technical field
The utility model relates to a kind of electric wire, relates in particular to a kind of ceramic fireproof=fire-proof silicone rubber wire cable.
Background technology
In the last few years, after the large-scale place of public amusement of domestic several families, chemical industry, colliery, commercial building fire caused painful people's life and property heavy losses, people had had more deep understanding to fire-fighting, fire safety.Sharp increase along with urban population, skyscraper, hotel, large supermarket, hospital, station, airport constantly increase, the construction of subway, tunnel traffic, and the increase of large-scale Public Physical Education, public place of entertainment, public transit facility, the importance of fire-fighting, fire safety shows especially out.How in the situation that fire ensures the unimpeded of electric power and communication within a certain period of time, win to greatest extent valuable rescue time, reduce personnel's injures and deaths and the loss of lives and properties, this is that people are always in the problem of constantly exploring.
What adopt both at home and abroad at present, is the fire-resisting cable that magnesium oxide mineral fire-proof insulation cable and mica tape twine mostly.Magnesium oxide mineral fire-proof insulation cable needs special manufacturing and processing equipment, and the equipment of in addition producing magnesium oxide mineral fire-proof insulation cable not only needs import, and very expensive, and fund input is too large; In addition, the outer jacket of magnesium oxide mineral fire-proof insulation cable is full copper, and is higher on the cost, is subjected to restriction to a certain extent aspect practical application; Add the specific (special) requirements of copper sheath magnesium oxide mineral fire-proof insulation cable in the processes such as the laying installation of production and processing, transportation, circuit and use, it is convenient as the production and processing of magnesium oxide mineral fire-proof insulation cable can not the image height molecular material, the laying installation difficulty is large, cost of raw material cost is high, be difficult to popularize on a large scale use, be difficult to especially promote at civil buildings etc.And the fire-resisting cable that mica tape twines, need in process of production multi-lay winding, because the restriction of process conditions, often easily cause overlapping the slot place defective to occur, mica tape embrittlement after burning, easily come off, also cause fire-resistant weak effect, thereby be difficult to ensure safe and smooth under fire condition of communication, electric power.
The utility model content
The utility model provides the ceramic of a kind of good flame retardation effect, long service life, low smoke, zero halogen fireproof=fire-proof silicone rubber wire cable in order to overcome the above problems.
The technical solution of the utility model is: comprise many conductors, described conductor extrudes the ceramic silicone rubber insulation layer outward and consists of core, and a plurality of cores extrude belting layer and consist of cable core, are provided with filling in the cable core, and described cable core is provided with ceramic silicon rubber oversheath outward.
The described glass fibre inserts that is filled to.
Described belting layer is the glass fibre band.
The utlity model has the characteristic that is better than General Purpose Rubber cable and flame retardant rubber cable; ceramic fireproof=fire-proof silicone rubber for cable has possessed the performance of ordinary silicon rubber cable at normal temperatures; ablation at thermal-flame forms hard housing afterwards, and the object that protection is burnt is not damaged.With ceramic fireproof=fire-proof silicone rubber wire cable, the hard housing of ablated rear formation is being protected electric wire, thereby has guaranteed the unimpeded of electric power, communication, for the valuable time has been won in evacuation and the rescue of personnel under the fire condition.
The utility model silicon rubber is to add white carbon, silicone oil in methyl vinyl silicone rubber, and other auxiliary agent, through after mixing, adds vulcanizing agent (two-2,5) in mill, then passes through mold pressing, extrudes, and makes cable.
This cable can be single cored structure, also multicore structure.The structure of single-core cable is copper conductor and fire-resistant silicon rubber insulation.The structure of multicore cable is copper conductor, fire-resistant silicon rubber insulation, glass fibre filling, glass fibre band, fire-resistant silicon rubber sheath.
The utility model has the advantages that:
1) in 650~1000 ℃ or above flame, through 90~180 minutes or above time ablation, silicon rubber is sintered into hard ceramic housing in a short period of time, hard ceramic housing has guaranteed circuit in ablated process, does not open circuit, not short circuit, do not prolong combustion, extraordinary anti-flammability is arranged, thereby guaranteed that circuit does not cut off the power supply in fire, provide guarantee for escaping and rescuing fire;
2) have the characteristics of fire-retardant, Halogen, low cigarette, meet the ROHS of European Union instruction, non-corrosiveness and toxicant and γ-ray emission during burning can not cause secondary harm to disaster-stricken people;
3) the hard housing that is sintered into, the vibrations that can bear spray and the some strength of certain water can guarantee that circuit does not rupture, not short circuit is for fire protection provides necessary prerequisite guarantee;
4) because extraordinary anti-flammability being arranged, the protectiveness of hard housing causes in conductor fusing (1083 ℃) process not short circuit, not on fire at carrying overload, excess load, short circuit current, the copper liquid that conductor fusing forms does not flow out outside the line, has stopped the disaster hidden-trouble that electric wire overload, short circuit cause;
5) possessed at normal temperatures high temperature resistant, anti-aging, the good characteristics such as electrical property of ordinary silicon rubber wire cable;
6) production of the present utility model, processing are the same with the processing technology of ordinary silicon rubber wire cable, do not need to change technique and increase equipment, need not to twine mica tape, asbestos etc., an extrusion molding, both can do fireprotection layer, insulating barrier, also can partly make sheath, simplify the processing technology of fire-resistant wire and cable, thus decrease cost;
7) under fire condition, can guarantee the unimpeded of communication, power circuit, for the quality time is won in the rescue of life, property, make significant contribution for reducing fire damage.
Good fire-fighting, fire performance that the utility model possesses are so that it can be widely used in public fire protection, the very high place of fire safety requirement.
