Description
Technical field
This utility model relates to field of cables, is specifically related to flexible mineral insulation fireproof cable.
Background technology
At present, the field wide variety of fire protection flame retarding cables such as skyscraper, hotel, hospital, subway, nuclear power station, power plant, Ore, oil, chemical industry are made up of the stranded conductor wire core of copper wire and Mica tape layer and the flame-retardant sheath being coated on outside conductor wire core, this type of cable flexility, fire prevention and water resistance are poor, when small space cabling, easily cause construction of cable damage, affect cable Long Service Life.
After ignition of cable, the material carbonization outside conductor wire core, form powdered substance, Mica tape layer can not resist foreign impacts, can not effectively insulate after meeting water.After fire occurs, cable sheath and conductor wire core lose insulating capacity, it is impossible to meet the requirement of supply line.
Existing common flame retardant cable is by conductor and is wrapped in the flame-retardant sheath outside core and forms, and cable pliability is poor, lays difficulty in narrow space place.And part flame retardant cable flame retardant coating by wrapped mica tape and extrudes flame-proof polyvinyl chloride or crosslinked polyethylene forms, temperature resistant grade is relatively low, after fire occurs, because of outside flame-proof polyvinyl chloride or crosslinked polyethylene carbonization, after being affected by external mechanical power, original flame retardant insulation comes off, mica tape is destroyed, and loses fire-resistant function.And release toxic gas and a large amount of smog, harm personal safety during burning.
Summary of the invention
In order to solve the problems referred to above, this utility model provides a kind of simple in construction, can effectively promote cable fire-proof performance and anti-external mechanical power is destroyed, and the flexible mineral insulation fireproof cable that pliability is good.
This utility model flexible mineral insulation fireproof cable, including outer jacket, in described outer jacket, bag is provided with fireprotection layer, is provided with some bundle conductor wires in described fireprotection layer, and described conductor wire includes conductor wire core and multilayer protective coating；Described multilayer protective coating ecto-entad is followed successively by waterproof layer, insulating barrier, split-phase colour band；Being filled with ceramic glass cord between described conductor wire and fireprotection layer, described insulating barrier includes that internal layer and outer layer, described internal layer are synthetic mica tape, and outer layer is ceramic refractory fibre band；Described conductor wire core uses multiply anaerobic soft copper silk to twist stranded conductor wire core through bundle.
Preferably, fireprotection layer is set to three layers, is followed successively by the 3rd fireprotection layer, the second fireprotection layer, the first fireprotection layer from inside to outside；Described 3rd fireprotection layer is synthetic mica tape, Ceramic silicon rubber band is wrapped forms, and described second fireprotection layer is formed by low-smoke halogen-free polyolefin flame-proof material and glass tape are wrapped, and described first fireprotection layer is made up of inorganic mineral material.
Preferably, waterproof layer is the waterproof layer that flame-retardant crosslinking polyethylene material is made.
Preferably, inorganic mineral material is the ceramic refractory fibre band that 0.6mm is thick.
Preferably, outer jacket is the outer jacket that low smoke, zero halogen polyolefine material is made.
This utility model simple in construction, utilizes fireprotection layer effectively to promote cable fire-proof performance, utilizes the multiple structure of ecto-entad to be effective against external mechanical power and destroys, and conductor wire core uses multiply anaerobic soft copper silk to twist stranded forming through bundle, and pliability is good.

Detailed description of the invention
This utility model flexible mineral insulation fireproof cable, including outer jacket 10, in described outer jacket 10, bag is provided with fireprotection layer, is provided with some bundle conductor wires in described fireprotection layer, and described conductor wire includes conductor wire core 1 and multilayer protective coating；Described multilayer protective coating ecto-entad is followed successively by waterproof layer 5, insulating barrier, split-phase colour band 2；Ceramic glass cord it is filled with between described conductor wire and fireprotection layer, ceramic glass cord has excellent low temperature and elevated temperature strength, fire-resistant and water-proofing performance, after filling this type of material, cable tensile strength substantially increases, and the construction of cable avoids external mechanical power and self gravitation to cause the construction of cable to damage after fire occurs.Described insulating barrier includes that internal layer and outer layer, described internal layer are synthetic mica tape 3, and outer layer is ceramic refractory fibre band 4；Described conductor wire core 1 uses multiply anaerobic soft copper silk to twist stranded forming through bundle.Fireprotection layer is set to three layers, is followed successively by the 3rd fireprotection layer the 7, second fireprotection layer the 8, first fireprotection layer 9 from inside to outside；Described 3rd fireprotection layer 7 extrudes for Ceramic flower silastic material or wrapped forms, and can form hard containment vessel, prevent external flame from spreading to conductor wire core after burning；Described second fireprotection layer 8 is formed by low-smoke halogen-free polyolefin flame-proof material and glass tape are wrapped, and described first fireprotection layer 9 is made up of inorganic mineral material.Waterproof layer 5 is made for flame-retardant crosslinking polyethylene material.Inorganic mineral material is the ceramic refractory fibre band 4 that 0.6mm is thick, has high-temperature stability, is resistant to 1000 DEG C of high temperature.Outer jacket 10 is made for low smoke, zero halogen polyolefine material.
Flexible mineral insulation fireproof cable main material uses the materials such as anaerobic soft copper, inorganic insulating material, low smoke, zero halogen polyolefin, ceramic cordage, Ceramic silicon rubber to make, and discharges without toxic and harmful, effectively reduce amount of smoke during burning.Firm containment vessel is formed after ceramic material combustion.Use three layers of fire proof construction, waterproof construction, ceramic cordage to strengthen cable tensile strength, effectively improve cable fire-proof performance and anti-external mechanical power is destroyed, after fire occurs, still ensure that cable properly functioning a period of time.Conductor wire core 1 uses multiply anaerobic soft copper silk to twist stranded forming through bundle, has softness and excellent conductive performance.This cable, because using anaerobic soft copper wire harness to tangle configuration formula, is allowed to that more general copper cash is stranded has good bending property, and Cable Bending Radius is reduced to 0.5 times of common cable.
