The content of the invention
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of controls of fireproof metal shield
Cable can be kept for certain conduction time, not generate toxic and harmful gas in the event of fire, be striven for the escape of personnel
Certain time is taken, power supply is provided for emergent fire-fighting equipment, and with high temperature resistant, anti-tampering, anticollision, resistance to compression, environmentally protective, machine
Tool intensity is high and can extend the effect of cable service life.
In order to realize above-mentioned target, the utility model adopts the following technical scheme：A kind of fireproof metal shield control
Cable processed, including insulated wire cores, the insulated wire cores include conductor, mineral insulation and fire lagging successively from the inside to the outside,
Several insulated wire cores are twisted into cable core, and the compound twining package tape of high fire-retardance, metal screen layer, interior shield are set gradually outside the cable core
Layer, the wrapped armor of galvanized steel strip Double-layer gap and fire retardant anticorrosion environment-friendly type oversheath, the cable core and high fire-retardance it is compound around
Gap between band is inorganic mineral fireprotection layer, and the fire lagging and fire retardant anticorrosion environment-friendly type oversheath are using ceramics
Change crosslinked polyolefin insulating material to extrude, the inorganic mineral fireprotection layer is ceramic inorganic mineral fire proofing material.
Further, the conductor is solid or twisted annealing copper conductor.
Further, mineral insulation is the wrapped ceramic mica carrying material of 4-6 layers of overlapping.
Further, the mineral insulation layer thickness 0.14-0.8mm, the ceramic mica band are overlapped wrapped rate and are
30%.
Further, the compound twining package tape of the high fire-retardance uses halogen-free high flame-retardant strip lap.
Further, the metal screen layer is overlapped wrapped using copper strips.
Further, the sheath extrudes for low smoke, zero halogen polyolefine material.
The utility model has the positive effect that：
1st, mineral insulation is to be overlapped wrapped 4~6 layers of ceramic mica band outside conductor, and fire resistant fire resisting can have
Effect delays insulation ag(e)ing, extends cable service life.
2nd, fire lagging and fire retardant anticorrosion environment-friendly type oversheath can be tied using ceramic polyolefine material after burning
Porcelain, do not drip, smoke density is small, do not generate harmful gas and effectively keep cable internal structure it is complete.
3rd, inorganic mineral fireprotection layer using can ceramic inorganic mineral fire proofing material extrude, the material have excellent fire insulation
Oxygen barrier acts on, and as being distributed in cable for filling larger area, knot ceramic, forms a firm housing after burning,
Hardness is high, anti-to beat, and prevents the running core of flame combustion.
4th, metal screen layer is overlapped wrapped by copper strips, has excellent shield effectiveness, prevents outer signals from disturbing cable, is protected
Protect cable effect.
5th, armor is wrapped using galvanized steel strip Double-layer gap, has superior mechanical, resistance to compression effect, and also having prevents from stealing
Arrive, insect bite the effects that.
