Abstract
The invention discloses a silicone rubber instrument cable. According to an insulation cable core, every two cable sets are twisted in pairs to form one cable set unit, a wrapping tape layer is arranged outside each cable set unit, and six cable set units are twisted again to form the cable core. A second wrapping tape layer, a total shielding layer, a total wrapping tape layer and an outer protective layer are sequentially arranged outside the cable core, wherein the second wrapping tape layer is made of halogen-free low-smoke flame-retardant glass fiber tape, the total shielding layer is woven by tinned copper wires, and the outer protective layer is formed by wrapping ceramic silicone rubber in an extruded mode. A center cable core is further arranged in the middle of the cable core. The center cable core is formed by wrapping mica tape fire-proof layers and inside liners around three insulated cable cores. A tinned copper conductor drainage wire is further arranged between the second wrapping tape layer and the total shielding layer. The silicone rubber instrument cable integrates the good and stable signal transmission function and the environment-friendly performance such as the low-smoke performance, the halogen-free performance and the fire-proof performance.
Description
Technical field
The invention belongs to electric wire field, relate to kind of a silicon rubber instrument cable.
Background technology
The signal transmission of the current distributing system in industrial and mining enterprises such as electric power, metallurgy, chemical industry, electronic computer system, automated system and detecting instrument, instrument etc., do connecting line.Substantially adopt traditional flame-proof polyethylene flame-resistant insulation pvc sheath and common silicone rubber for cable.Flame-proof polyethylene flame-resistant insulation pvc sheath cable heatproof is 105 ℃, and common silicone rubber for cable is high temperature resistant is only 180 ℃.In the time that fire occurs, cable is burned, there is the amount of being fuming high, there are halogen and poisonous corrosive gas to disengage, are unfavorable for like this withdrawing and rescuing of personnel, and owing to there being the release of the corrosivity gas such as halogen, with airborne steam in conjunction with form strong acid mist, be attached on electric device, seriously reduce the dielectric strength in equipment and earth connection loop, cause " secondary disaster ".
Summary of the invention
There is the dangerous situation that fire occurs to use the problem existing for overcoming existing Common Instrument cable at some, the object of the present invention is to provide kind of a silicon rubber instrument cable, is a kind of cable that the environmental-protecting performances such as low cigarette, Halogen, fire prevention and good stable signal transfer functions are integrated in one.
The solution of the present invention is as follows: a kind of silicon rubber instrument cable, insulated wire cores is by two line group pair twist composition line group unit, online group unit is outside equipped with belting layer, six roots of sensation line group unit is twisted into cable core again, and cable core is disposed with the second belting layer that adopts LSOH anti-flaming glass fibre belt to make outward, total screen, overall budget belt and the employing ceramic silicon rubber of tinned copper wire braiding extrudes the outer jacket of formation; Yi Gen center core is also set in the middle of described cable core, and described center core is by the outer wrapped mica tape fireprotection layer of three insulated wire cores, inner covering; Between the second described belting layer and total screen, a tinned copper conductor drainage thread is also set; Described insulated wire cores extrudes enviroment protective ceramic SiClx rubber insulation outward by conductor and forms.
Further, between described cable core and the second belting layer, adopt low smoke, zero halogen glass fiber rope to fill.
Further, described thickness of insulating layer is 0.5-3mm.
Wrapped mica tape on the conductor of cable of the present invention, insulating layer material adopts enviroment protective ceramic SiClx rubber-covered material, and this material is compared with common polyethylene, nontoxic, tasteless at normal temperatures, has good flexibility and elasticity, possesses the feature of silicon rubber; Under flame condition, can very effectively stop burning away of flame; And give up smoking completely after burned 2 ~ 4min.The outer jacket of cable adopts environment-friendly ceramic SiClx rubber sheath material.This material has taken into full account the Halogen of cable, low cigarette, fire resistance, adopts novel high polymer ceramic silicon rubber composite material, to around personnel and equipment without illeffects.The auxiliary packing material of cable and band material are to adopt halogen-free flameproof glass fiber material, not only have good fire resistance, and are all not halogen-containing environment-friendly materials.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of silicon rubber instrument cable, insulated wire cores is by two line group pair twist composition line group unit, online group unit is outside equipped with belting layer 3, six roots of sensation line group unit is twisted into cable core again, and cable core is disposed with the second belting layer 4 that adopts LSOH anti-flaming glass fibre belt to make outward, total screen 5, overall budget belt 6 and the employing ceramic silicon rubber of tinned copper wire braiding extrudes the outer jacket 7 of formation; Yi Gen center core 8 is also set in the middle of described cable core, and described center core 8 is by the outer wrapped mica tape fireprotection layer of three insulated wire cores, inner covering; Between the second described belting layer 4 and total screen 5, a tinned copper conductor drainage thread 9 is also set.Described insulated wire cores forms by extruding enviroment protective ceramic SiClx rubber insulation 2 outside conductor 1.
Between described cable core and the second belting layer 4, adopt low smoke, zero halogen glass fiber rope to fill.Described thickness of insulating layer is 0.5-3mm.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and revise; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
