Abstract
The invention discloses an environment-friendly and safe fireproof cable which comprises a cable core and a cable outer layer, wherein the cable core is formed by twisting three conductor cores; each conductor core is formed by extruding and wrapping an insulation shielding layer, an XLPE (cross linked polyethylene) insulation layer, a conductor shielding layer and a mica tape fireproof layer on a conductor from outside to inside in sequence; one ground wire core is arranged in each conductor shielding layer; the cable outer layer is formed in a way that the cable core is extruded and wrapped by a semiconductive waterproof tape, a lining layer, a copper wire and copper tape combined shielding layer, a semiconductive buffer waterproof layer, an aluminium plastic composite tape and a low smoke zero halogen flame retardant fireproof sheath from inside to outside in sequence; a ground wire core is arranged on the semiconductive buffer waterproof layer. The environment-friendly and safe fireproof cable is fireproof, waterproof, non-toxic, environment-friendly, high in safety, good in shielding performance, good in current balance, and capable of still maintaining energization and stable current under specific disaster conditions.
Description
Technical field
The present invention relates to cable, relate in particular to a kind of environmental protection and safety type fireproof cable.
Background technology
At present, the high occasion of fire safety condition such as domestic skyscraper, oil, mine, metallurgy, boats and ships, power station, subway, tunnel, the cable insulation using, restrictive coating mostly adopts the insulating material of Halogen.Once fire spreads, not only can produce a large amount of dense smoke, and can produce the very strong hydrogen halide of corrosivity with " secondary disaster ", jeopardize people's life, harm equipment and contaminated environment.Even adopt the flame-retardant insulating material of Halogen, low halogen; the time that also can only delay flame-retardant insulating material and burnt till powder; burnt if continued; just gradually powder and come off; lose protective effect; electric wire is easy to breakdown and causes short circuit, thereby is difficult to ensure safe and smooth under fire condition of communication, electric power.Along with high speed development and the World Environment Organization requirement to environmental protection of World Economics; anxious environmental type safety cable to be developed has fire prevention to meet the needs of human kind sustainable development, to provide, waterproof, nontoxic, environmental protection, safe; advantages of good shielding performance, the cable that current balance type is good.
Summary of the invention
In order to meet above-mentioned requirements, the object of the invention is to provide a kind of environmental protection and safety type fireproof cable.
The solution of the present invention is as follows: a kind of environmental protection and safety type fireproof cable, comprise cable inner core and cable outer layer, and cable inner core is by three stranded forming of conductor wire core; Described conductor wire core is to be extruded on conductor and to form from outside to inside successively by insulation screen, XLPE insulating barrier, conductor shield and mica tape flame retardant coating; In described conductor shield, be provided with a ground core; Cable outer layer is to be extruded in from inside to outside on cable inner core and to form successively by semiconductive waterstop, inner covering, copper wire copper strips combination screen, semi-conductive buffer water-blocking band, aluminium-plastic tape and low-smoke non-halogen flame-retardant fireproof; In described semi-conductive buffer water-blocking band, be provided with a ground core.
Described conductor is pressed concentric type by some identical soft round copper wires of diameter, and each level forms according to different direction strand systems in succession.
Described copper wire copper strips combination screen is wrapped on one deck copper strips and is formed by layer of copper filament winding.
Beneficial effect of the present invention: the present invention has fire prevention, waterproof, nontoxic, environmental protection, safe, advantages of good shielding performance, current balance type is good, is suitable for still maintaining under specific disaster scenario the cable of energising and stabling current.
