Summary of the invention
In order to solve above-mentioned prior art problem, the utility model provides a kind of high flame retardant, pliability better flexible mineral matter fireproof cable.
The technical solution of the utility model is: a kind of flexible mineral matter fireproof cable, comprise many cable cores and sheath, it is characterized in that: described every root cable core includes conductor, is coated on the flame retardant coating of conductor outside surfaces, the color insulating barrier be coated on outside flame retardant coating, many cable cores closely surround into a ring-type, anti-elater is filled with in ring center, ring-type is wrapped with mineral-filled layer, and mineral-filled layer is coated with band, band outer cladding sheath.
Described cable core is 5.
Described conductor is made up of a thick copper lines.
Described flame retardant coating is fire-resistant isinglass belt, fire-resistant isinglass belt is a kind of high performance mica insulation goods, there is excellent resistance to elevated temperatures and flame resistance energy, during this mica tape normality, there is good flexibility, substantially the volatilization of harmful vapors is there is not when meeting naked light burning, not only effective for cable, and very safe.
Described color insulating barrier is crosslinked polyolefin layer.
Described anti-elater is made primarily of polyaryl fiber, and hot strength is high, wettability low (not absorbing moisture), and dimensionally stable, heat-resisting good, wear-resisting, cut resistant, acidproof, shock-resistant, flame resistance is excellent, adds the pliability of cable and enhances tensile property.
Described mineral-filled layer is magnesium hydroxide inorganic mineral material, and heatproof is high, and highly difficult combustion, play fabulous heat insulation, fire-retardant fireproof protective effect, harmfulness is little, and smoke suppressing effect is good.
Described band is halogen-free flameproof fire resistant belt.
Described sheath is polyolefin jacket.
The beneficial effects of the utility model are: first, the utility model fills many one decks inorganic mineral material in traditional fire-resisting cable structure, higher fire safety and environmental-protecting performance is had than traditional cable, effectively can reduce the release of cable at high temperature harmful substance, ensure that cable can keep normal in certain hour after combustion and run; Secondly, packing material of the present utility model and sheath material are all bittern-free flame-proof material, can play more effective fire retardation, and low smoke and zero halogen are nontoxic, can greatly reduce the injury suffered by human body, instrument and equipment when fire occurs when burning; The utility model adopts anti-elater to fill in the ring center that each cable core surrounds, and adds the pliability of fireproof cable and strengthens its tensile property.
Accompanying drawing explanation
