Abstract
The utility model relates to a high temperature and corrosion resistant mineral compound insulated fireproof cable which includes conductors, insulating layers, a filling layer, a fire-proof layer and a sheath. The cable is characterized in that the outside of each conductor is wrapped with the insulating layer to form an insulating wire core; ceramic fiber ropes are filled among the insulating wire cores to form the filling layer; the outside of the filling layer is wrapped with the fire-proof layer; and the outside of the fire-proof layer is provided with the sheath. In the above technical scheme, the long-term working temperature of the cable conductor is 200 DEG C, the lowest using temperature is -65 DEG C, and the cable conductor is acid and alkali resistant; the fire resistance rating of the cable can satisfy the C, W, Z rating fire resistance test requirements in the BS6387:1994, i.e. C-flame temperature is 950+/-50 DGE C, combustion time is 3h, W-water spray, Z-flame temperature is 950+/-50 DEG C; the cable is resistant to mechanical impact, is excellent in flexibility, and is easy to bend; the long-length production is realized, the flame retardant property is V-0 grade, and the ROHS environmental directive is performed.
Description
Technical field
The utility model relates to a kind of cable, and specifically a kind of high-temperature resistant anti-corrosive mineral compound inslation fire-resisting cable is applied in the occasions higher to the fire safety conditional request such as skyscraper, electric power, oil, chemical industry, boats and ships, belongs to the cable technology field.
Background technology
In the market, the fire-resisting cable price is more expensive, generally is applied in the occasions higher to the fire safety conditional request such as skyscraper, electric power, oil, chemical industry, boats and ships, is the indispensable cable of emergency power supply, fire pump, elevator, communication signal system.The universalness batch production of this type cable, but these fire-resisting cables all are to adopt Mica tape fire-resistant at present, Insulation Material adopts common crosslinked polyethylene mostly.Because the flame retardant coating Main Ingredients and Appearance is mica, it is to be composited with polyester, glass fibre etc., comes off easily in often crooked occasion, thereby causes the fire-resistant requirement that do not reach, and has potential safety hazard; What existing mineral insulated cable fire resistance was best in addition is the magnesium oxide mineral insulated cable, but that it has again is not flexible, can not big-length production, be subject to the shortcoming of acid and alkali corrosion and moisture-sensitive, so that can not popularize in a large number.
Summary of the invention
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of high-temperature resistant anti-corrosive mineral compound inslation fire-resisting cable, this cable has the advantages that but fire resistance rating height, corrosion-resistant, good bending property, high-low temperature resistant environment for use and big-length are produced, and is particularly useful for skyscraper, electric power, oil, chemical industry, boats and ships etc. to the higher and corrosion-prone use occasion of fire safety conditional request.
The utility model technical solution problem adopts following technical scheme: a kind of high-temperature resistant anti-corrosive mineral compound inslation fire-resisting cable comprises conductor, insulating barrier, packed layer, fireprotection layer and sheath, it is characterized in that: every conductor is surrounded with insulating barrier outward and consists of insulated wire cores, adopt the ceramic cordage to fill between each insulated wire cores and form packed layer, the outer wrapped fireprotection layer of packed layer, fireprotection layer is provided with sheath outward.
Insulating barrier is comprised of mica belt and the compound belt of ceramic fireproof＝fire-proof.
Fireprotection layer is comprised of the compound belt of ceramic fireproof＝fire-proof and high flame retardant gluing glass belt.
Sheath adopts the fluoroplastics material.
The utility model cable insulation adopts mica tape and ceramic fireproof＝fire-proof composite band as composite insulation layer, changes traditional single extruded insulation form; Adopt the ceramic cordage to fill during stranding, outside ceramic fireproof＝fire-proof composite band and high flame retardant gluing glass fibre belt form the composite fire layer, have improved the flexibility of cable; Sheath material adopts the sheath of anti-fluoroplastics, has improved acid and alkali corrosion and the high characteristic of temperature resistant grade of cable.
Adopt the cable conductor long-term work temperature of technical solutions of the utility model can reach 200 ℃, minimum serviceability temperature-65 ℃, performance with acid and alkali-resistance environmental corrosion, this cable fire grade can satisfy C, W, the requirement of Z class rank fire resistance test of British Standard BS 6387:1994, be 950 ± 50 ℃ of C-flame temperatures, burning time: 3h, W-water spray, 950 ± 50 ℃ of Z-flame temperatures and mechanical shock, and softness is good, flexible, but big-length production, fire resistance can reach the V-0 level, meets ROHS environmental protection instruction.
