Abstract
Disclosed is a ceramic silastic insulated flame resistant cable, which uses conductors coated with flame resistant insulation layers as cable cores, a heat resistant filling layer is arranged among cable cores and added with a protective layer outside, and a protective jacket layer is coated on the cable external. The ceramic silastic insulated flame resistant cable is characterized in that the flame resistant insulation layer uses ceramic silastic as a material, and has the advantages of excellent flame resistance, when fire is breaking out, the cable line can be kept in normal operation for a certain time, thereby helping rescue operation and fastest reducing causalities and financial loss.
Description
Technical field
The utility model relates to fire-resisting cable, relates in particular to a kind of potteryization fire-resistant silicon rubber insulated fireproof cable.
Background technology
Fire-resisting cable is widely used in important department and public places such as skyscraper, subway, power plant, nuclear power station, simultaneously many engineerings begin to trend towards the demand to the low smoke and zero halogen fire-resisting cable, so that after breaking out of fire, supply line can keep the normal operation of certain hour, help carrying out of rescue work, reduce casualties and damage to property as far as possible.
At present both at home and abroad more adopt be magnesium oxide mineral insulation fire-resisting cable and mica tape wrapped/fire-resisting cable of plastics (rubber) compound inslation, the former manufacturing cost height, it is big to lay difficulty; The latter has stability scarcely, and a lot of mica tapes are thicker, hardness is big, the binder content height, and mica sheet comes off easily in wrapped process, the particularly manufacturing of small bore fire-resisting cable, and the quality of product is difficult to guarantee.In addition, though conventional silicon rubber becomes silicon dioxide attached to the cable conductor surface after burning, it has fire resistance, but the silicon dioxide after the burning is powdery, no adhesive force and certain intensity, electric wire and cable conductor still is easy to be in contact with one another and causes short circuit, thereby fire-resistant effect is still relatively poor.
Potteryization fire-resistant silicon rubber material is to be base-material and carrier with silicon rubber, and adding has inorganic silica flour filler, constitution controller and other auxiliary agent, through vacuum kneading, mixing, makes sizing material, is sintered into the potteryization body through high temperature or flame.Have certain mechanical strength and excellent electric insulating energy, but in fire-resisting cable, be not applied so far.
The utility model content
The utility model is for avoiding the problem of above-mentioned existing in prior technology, a kind of pottery silicon rubber insulation fire-resistant cable that possesses excellent fire resistance is provided, make fire that the normal operation that the back cable line still can keep certain hour take place, so that for rescue work brings help, reduce casualties and damage to property.
The utility model adopts following technical scheme:
The utility model potteryization silicon rubber insulation fire-resistant cable, described cable are to be cable core with the conductor that is coated with refractory insulating layer, and high temperature resistant packed layer and protective layer are set between each cable core, and the appearance of cable is an external sheath layer.
Design feature of the present utility model is that refractory insulating layer is to be material with the pottery fire-resistant silicon rubber.
Design feature of the present utility model also is:
That conductor adopts is zinc-plated or not zinc-plated, multiply or single copper cash; High temperature resistant packed layer is the glass fiber rope; Protective layer is the heat-resistant fireproof band; External sheath layer adopts plastic sheath, rubber sheath, or is material with the pottery fire-resistant silicon rubber.
At the fire-retardant neck bush of the outer setting of protective layer, between fire-retardant neck bush and external sheath layer, armour is set.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the refractory insulating layer in the utility model is to be material with the pottery fire-resistant silicon rubber; after burning through high temperature or flame; can form the potteryization solid; have certain mechanical strength and excellent electric insulating energy; and the time of burning is long more, the more high potteryization effect of temperature is obvious more, can play the effect of the normal operation of protection circuit preferably.
2, the pottery fire-resistant silicon rubber that is adopted in the utility model, nontoxic, tasteless, before unburned, have flexibility and elasticity preferably.
3, the utlity model has the insulated fireproof characteristic of magnesium oxide mineral insulation fire-resisting cable, than mica tape wrapped/the fire-resisting cable manufacturing process of plastics (rubber) composite fire insulation is simpler, the cost performance height.
4, the conductor in the utility model adopts multiply or single copper conductor, has the same good bending property of common cable.Its heat-resistant fireproof band and external sheath layer material are easy to get, the performance maturation.
5, the setting of fire-retardant neck bush of the utility model and armour 7 has improved the mechanical performances such as pounding, strike and hit of cable under the fire combustion case.
Description of drawings
Fig. 1 is the utility model four-core type construction of cable schematic diagram.
Fig. 2 is the utility model three-hole construction of cable schematic diagram.
Number in the figure: 1 conductor, 2 refractory insulating layers, 3 high temperature resistant packed layers, 4 protective layers, 5 external sheath layers, 6 inner coverings, 7 armours.
Below pass through embodiment, and in conjunction with the accompanying drawings the utility model is further specified.
Embodiment
Referring to Fig. 1, conductor 1 adopts zinc-plated or not zinc-plated, multiply or single copper cash, and its performance meets the requirement of GB/T3956-1997 conductor.Refractory insulating layer 2 adopts potteryization fire-resistant silicon rubber material, this material is base-material and carrier with silicon rubber, adds inorganic silica flour filler, constitution controller and other auxiliary agent, through vacuum kneading, mixing, make sizing material, refractory insulating layer 2 closely is extruded on the conductor 1.High temperature resistant packed layer 3 is the glass fiber rope.Protective layer 4 is the heat-resistant fireproof band; External sheath layer 5 adopts plastic sheath.
For further strengthening the fire resistance of cable, also can adopt the pottery fire-resistant silicon rubber material identical with refractory insulating layer.
Different is fire-retardant neck bush 6 is set, between fire-retardant neck bush 6 external sheath layers 5 armour 7 is set in the appearance of protective layer 4 for structure shown in Figure 2 and structure shown in Figure 1, improves the mechanical performances such as pounding, strike and hit of cable under the fire combustion case with this.
