Description
Technical field
The present invention relates to a kind of cable, particularly relate to a kind of control cables with anti-interference fire resistance.
Background technology
Along with the fast development of the industries such as China's metallurgy, electric power, electronics, automation and informatization and network, the requirement of low smoke no-halogen wire cable has clearly been proposed to use in " the civil buildings electric wire fire protection design rules " of East China Municipal Architecture Design and Research Institute release in 2002.Along with the development of modern science and technology and the RoHS of European Union environmental protection instruction
Propose, fail safe, the feature of environmental protection of electric wire product are had higher requirement.For places such as oil platform, mine, skyscraper, hotel, large supermarket, hospital, subway, tunnel, warehouse, civilian installations, having cable safe, fire-resistant, environmental-protecting performance will more and more be subject to people's attention and favor.This is not only World Environment Organization to the requirement of environmental protection, also is the development trend of countries in the world, especially the global people's common heartfelt wishes.In safety, the place that fire-resistant and environmental requirement is very high, after breaking out of fire, non-corrosiveness, toxicant and γ-ray emission during cable fire, can not cause secondary harm to disaster-stricken crowd, circuit can ensure that electric power system normally moves within a certain period of time, can get the quality time for rescue work, reduce to a great extent the people's Loss of Life and property.
At present, fireproof control cable generally adopts the wrapped mode that adds insulation of fire-resistant isinglass belt in the cable industry, but Mica tape class fire-resisting cable is in wrapped or crooked process, mica sheet easily comes off, can not pass through spray, vibratory test, and the mica tape kind is more again now, quality is uneven, less stable, the very difficult fire resistant quality that guarantees cable.Secondly, the environmental requirement that the employed insulation of common fireproof control cable and sheath material mostly all contain halogen or do not reach RoHS Directive.Moreover the wrapped production of small bore fireproof control cable is restricted, and the fire resistance quality more can't be protected.Common silicon rubber control cable becomes silicon dioxide after burning; although silicon dioxide is attached to the cable conductor surface; has certain fire resistance; but the silicon dioxide after the burning is powdery or is crisp grey shape; without adhesive force, easily come off, lost protective effect; easily cause short circuit, the fire resistance of cable reduces relatively greatly.In high temperature silicon rubber, add the fire-resisting ceramic silicone rubber material that white carbon, silicone oil, antistructurizing agent and other auxiliary agent are made, the performance that possesses ordinary silicon rubber under the normal temperature, through forming hard ceramic shell after the thermal-flame calcination, has good heat insulation isolated flame effect, make insulation still have certain mechanical strength and good electrical insulation capability, cable itself does not prolong combustion, not short circuit, does not cut off the power supply, and plays good fire-resistant effect.
Summary of the invention
The purpose of this invention is to provide a kind of anti-interference fireproof control cable, to overcome the technological deficiency of existing fire-resisting cable, improve fire resistance, environmental-protecting performance and the interference free performance of cable.
Anti-interference fireproof control cable of the present invention comprises the cable conductor that forms by being no less than an eradication edge core, be centered around the screen on the described cable conductor, and extrude fire-resistant rubber sheath on described screen, wherein insulated wire cores comprises the conductor of being made by electric conducting material and is extruded in the outer field refractory insulating layer of described conductor, in addition
The anti-interference fireproof control cable of the present invention is surrounded with the glass fabric band between cable conductor and the screen, between insulated wire cores and and the glass fabric band between the slit in be filled with glass fiber.
Wherein, described conductor is single conductor or strands conductor.
Preferably, the screen of control cables of the present invention comprises that copper wire interlacing net and compound copper-plastics band are two-layer, and described copper wire interlacing net is wrapped in outside the glass fabric band, and the compound copper-plastics band copper face is inwardly vertical, and to wrap in the copper wire interlacing online.
Among the present invention, the width of compound copper-plastics band should be greater than the girth of the structure of its lower parcel, so that the vertical copper wire interlacing that wraps in of compound copper-plastics band when online, can be formed overlap joint.
Wherein, fire-resistant rubber sheath and refractory insulating layer all adopt the refractory ceramics fire-resistant silicon rubber to make.
Anti-interference fireproof control cable of the present invention filled glass fiber silk in the slit of cable conductor, and tighten with the glass fabric band, well high temperature resistant and fire resistance had.
Because the refractory ceramics fire-resistant silicon rubber uses working temperature higher, can reach 180 ℃ and more than, greatly improved the ampacity of cable, cable is in same ampacity situation, the cross section can further reduce.
Anti-interference fireproof control cable of the present invention has good electrical insulation capability, high temperature resistant, resistance to low temperature and excellent fire-resistant, environmental protection, interference free performance, processing technology is simple, transportation is laid conveniently, cost performance is higher, the normal operation that cable line still can keep certain hour when fire occured, rescue work is brought very large help, can reduce casualties and damage to property to a great extent.
Anti-interference fireproof control cable of the present invention has also solved following problem except having higher electrical insulation capability and high temperature resistant, resistance to low temperature: 1, fire resistance is better than existing fireproof control cable.2, cable material Halogen, heavy metal free when burning, light transmittance is high, environmental protection, and human body, environment are not exerted an influence.3, cable adopts the dual shield mode, has good anti-interference and low radiance, can effectively control external electromagnetic field to the impact of transmission line on the one hand, avoids Signal Fail, and noise increases, the phenomenons such as transmission error code; Can reduce on the other hand the interior signal of cable to electromagnetic radiation on every side, reduce periphery electromagnetic environment and pollute.
