The fireproof control cable provided by the utility model overcomes a shortcoming of poor fire-resisting performance of a prior control cable, and has characteristics of high fire-resisting temperature, high fire-resisting durability, simple manufacturing technique, and convenient usage and installation.
Description
Technical field
The utility model belongs to the control cable field, is specifically related to a kind of novel fire-type control cable.
Background technology
At present, a kind of fireproof cable that generally uses is copper pipe mineral cables, and cable core is that single copper conductor forms single core or multicore; Skin is the copper pipe of using as sheath, makes separator by magnesia between copper conductor and the copper pipe, though simple in structure; Can prevent fires, but need repeated annealing, drawing, labour intensity is big; Not only hardness is very big, and has increased construction cost and time; In addition, what also have to adopt is that magnesia mineral fire-proof insulation and mica tape twine and reach fire-resistant requirement, but owing to the outer jacket of magnesia fire-proof insulation cable has special requirement; Aspect practical application, receive restriction to a certain degree, and the refractory material that mica tape twines, because the restriction of technology; Often be prone to cause overlapping the slot place defective to occur, morning glow master tape embrittlement comes off easily; Also cause fire-resistant weak effect, at present, the fireproof cable that oneself knows; Time that can be fire-resistant does not all surpass 90 minutes, is difficult to the effect that reaches desirable.
The utility model content
The technical problem that the utility model will solve is the shortcoming to existing control cable fire resistance difference, and a kind of novel fire-type control cable that a kind of refractory temperature is high, fire resistance period is long, manufacturing process is simple, easy to install and use is provided.
In order to solve the problems of the technologies described above; The utility model provides following technical scheme: a kind of novel fire-type control cable; Wherein, Comprise cable core group, mineral stone cotton cord packed layer, the second glass fiber belt, potteryization silica gel restrictive coating and braid from the inside to the outside successively, the cable core group includes 2～37 cable cores, mica mineral band, potteryization silicone insulation layer and the first glass fiber belt, and mica mineral band, potteryization silicone insulation layer, the first glass fiber belt are wrapped in outside the single cable core successively.
Adopt a kind of novel fire-type control cable of the utility model technical scheme; Owing to comprise cable core group, mineral stone cotton cord packed layer, the second glass fiber belt, potteryization silica gel restrictive coating and braid from the inside to the outside successively; The cable core group includes 2～37 cable cores, mica mineral band, potteryization silicone insulation layer and the first glass fiber belt; Mica mineral band, potteryization silicone insulation layer, the first glass fiber belt are wrapped in outside the single cable core successively, and outermost braid at first plays the fireproof effect, and mica mineral band, the first glass fiber belt, mineral stone cotton cord packed layer, the second glass fiber belt are the fire protecting performance excellent material and form; Potteryization silicone insulation layer, potteryization silica gel restrictive coating have possessed the performance of common silica gel under the normal temperature state; Softness, and in the time of 600～1300 ℃, can be cured as hard pottery, play anti-fire action; Therefore refractory temperature is high, manufacture craft is simple, and easy to install.
Further, a kind of novel fire-type control cable, wherein, described cable core many copper cash bundles strand of serving as reasons forms, and the area of section of cable core is 0.5～6.0 ㎜
2The more single copper conductor of cable core of many copper cash bundle strands is soft, helps installing and using.
Further, a kind of novel fire-type control cable, wherein, described mica mineral band is to be suppressed on the glass fiber guipure by mica powder to form.Mica powder has insulating properties, characteristics such as high temperature resistant, and it is suppressed on the glass fiber guipure, is convenient to processing, and intensive even distribution, helps further fire prevention.
Further again, a kind of novel fire-type control cable, wherein, described braid is the network structure that forms with copper wire, tinned copper wire, aluminum-magnesium alloy wire, steel wire, glass braid.The fusing point of copper is about 1083.4 ℃, and is hard; The fusing point of tin is about 232 ℃, and is soft, and the fusing point of aluminium is about 660 ℃, and is soft; Magnesium fusing point about 648.9 is soft; About 1515 ℃ of the fusing points of steel, hard, utilize the both favourable fire prevention of netted braid of copper, tinned copper wire, almag, steel wire, glass braid, avoid braid to melt, guaranteed the flexibility of control cable again, avoid influence to install and use.
Adopt a kind of novel fire-type control cable of the utility model technical scheme, when surrounding environment is in just often, cable core, potteryization silicone insulation layer, potteryization silica gel restrictive coating, the braid that the copper cash of bundle strand is formed all guaranteed the flexibility of cable; When the control cable surrounding environment was caught fire, at first, outermost braid can at first be prevented fires; Avoid the internal material calcination, make braid fusing, potteryization silica gel restrictive coating can form hard pottery fire prevention when temperature is too high; Secondly, when pottery was burnt the crack or damages, the mineral stone cotton cord packed layer and the second glass fiber belt were further prevented fires; And the first glass fiber belt, potteryization silicone insulation layer and mica mineral band are finally protected cable core, avoid cable core to receive the influence of flame high temperature, and holding current or signal are unimpeded; Can bear 950 ℃ of high temperature; Under the situation that has bump or water to drench, secure communication is about 3 hours, and refractory temperature is high, fire resistance period is long, manufacturing process is simple, easy to install and use.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model technical scheme is further specified:
Fig. 1 is the section structure sketch map of a kind of novel fire-type control cable embodiment of the utility model.
Embodiment
As shown in Figure 1; A kind of novel fire-type control cable of the utility model; Wherein, Comprise cable core group, mineral stone cotton cord packed layer 5, the second glass fiber belt 6, potteryization silica gel restrictive coating 7 and braid 8 from the inside to the outside successively, the cable core group includes 2～37 cable cores 1, mica mineral band 2, potteryization silicone insulation layer 3 and the first glass fiber belt 4, and mica mineral band 2, potteryization silicone insulation layer 3, the first glass fiber belt 4 are wrapped in outside the single cable core 1 successively; The cable core 1 many copper cash 9 bundle strand of serving as reasons forms, and the area of section of cable core 1 is 0.5～6.0 ㎜
