Description
Technical field
The present invention relates to a kind of power cable, be specifically related to a kind of copper-core silicon rubber insulation fire-resistant polyolefin jacket zero-halogen low-smoke flame-retardant electrical cable.
Background technology
Development along with society, the progress of science and technology, numerous power plant, smelter, petroleum chemical enterprise develop to large-scale grouping of the world economy direction, and skyscraper, place of public amusement, subway and underground street etc. continue to bring out, its power consumption grows with each passing day, the also corresponding increase of the kind of electric wire and consumption.But electric wire is transmission ﹠ distribution electric energy, transmission information both, is again " blasting fuse " of fire hazardous.Yet common cable can not be switched on during cable fire when actual breaking out of fire.But many important events are just in case during breaking out of fire, evacuating personnel, and the illumination of passage, the fireproof alarming device, automatic fire-fighting facility and other emergency set all require when fire takes place cable can keep at the appointed time normal power-up.Therefore, people develop fire-resisting cable.
Fire-resisting cable: refer to that under the regulation experimental condition, sample is burned in flame, still can keep the performance of normal operation within a certain period of time.Its basic characteristic is exactly: power cable still can be kept the operate as normal of this circuit a period of time under burning condition.Generally be exactly, fireproof power cable can be kept the normal power supply of a period of time when fire takes place, and to keep illumination and transmission signals, the protection personnel have the time enough safe escape, and is beneficial to fire extinguishing and reduces loss.
Domestic and international existing fireproof power cable is the wrapped fireproof power cable of mica tape at present, and its structure is followed successively by from inside to outside: conductor, and---------reinforced layer insulate wrapped mica tape---wrapped, the filling of stranding---sheath; What wherein play fire-resistant effect is mica tape; Insulating material is identical with common power cable; Filling, wrapped material can adopt common material or flame retardant type material as required; Sheath material can be selected flame-proof polyvinyl chloride, low cigarette, low halogen, Halogen, hypotoxicity sheath material for use according to fire resistance rating.
Because playing the mica tape of hot-face insulation effect is to be equipped with suitable adhesive by mica paper and reinforcement with electrician's alkali-free glass fiber cloth to cut the insulating material that forms after curing drying, in producing wrapped process, mica powder is along with the bending coiling of belt is easy to come off, directly influence the fire resistance of product, and mica tape makes moist easily and causes power cable to puncture; Process structure complexity, mica tape and reinforced layer must adopt wrapped mode to be coated on the power cable conductor surface, and wrapped speed is slow, efficient is low, influence the delivery date of product.In addition, the permission working temperature of different mica tapes differs greatly processing difficulties.More than various defectives cause adopting the fire-resistant power cable fire resistance of mica tape very unstable.
For example: publication number is CN101447252A, and the Chinese invention patent that open day is on June 3rd, 2009 discloses the patent of invention that a kind of name is called " novel flame resistant cable ".This fire-resisting cable comprises mica tape, the insulating barrier that extrudes and the oversheath of vertical bag on conductor and the conductor, and mica tape is provided with the glass tape of tightening mica tape, is provided with the inorganic insulation powder bed between conductor and the mica tape, and insulating barrier is extruded on the mica tape of being tightened.This invention is from improving the adhesion force between conductor and the mica tape, avoid conductor to expose the cut cable face phenomenon and set out, with silicone adhesive with the inorganic insulation powder adherence on mica tape, powder fills up the recess of mica tape, the contact area of conductor and mica tape is increased, and adhesion force strengthens.Substrate surface at mica tape also adheres to the inorganic insulation powder, tightens back extruded insulation layer with glass tape on the mica tape, improves the contact-making surface of mica tape and insulating barrier.But this patent does not still have to overcome fully when using mica tape, and moisture-sensitive causes power cable to puncture; The process structure complexity, defective such as wrapped speed is slow, efficient is low.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, a kind of copper-core silicon rubber insulation fire-resistant polyolefin jacket zero-halogen low-smoke flame-retardant electrical cable with new structure is provided, this power cable reduces cost when satisfying the flame-retardant performance, enhance productivity, make the power cable fire resistance more stable.
