Abstract
The utility model discloses a high fire -retardant flexible fireproof cable with cut off waterproof construction, including three conductors, every conductor outward all in proper order the cladding have mineral flame retardant coating, silicone rubber insulating layer to constitute insulation core, three insulation core strand the beam forming each other and constitute the cable core, the cable core through extrusion molding in the isolation layer, the outer cladding of isolation layer has the fire prevention around the covering, the fire prevention is equipped with interval distribution's metal separation sleeve outward around the covering, the cladding has low smoke and zero halogen flame retardant polyolefin oversheath layer outside the metal separation sleeve. The utility model is suitable for an among the power supply and distribution system of high fire -retardant requirements such as cable pit, cable shaft, tunnel, there are low cigarette in specially adapted school, market, government organs etc. Do not have place steamed, fire -retardant requirement, have improved the fire prevention and the humidity resistance of joint department of cable.
Description
technical field:
The utility model relates to fireproof cable, particularly relates to a kind of high flame retardant flexible fire-proof cable with cutting off waterproof construction.
background technology:
Current domestic common fireproof cable is by copper conductor, mineral insulation and and the rigidity fireproof cable that forms of copper sheath.Rigidity fire-resisting cable has very high fire resistance, but because adopt copper sheath, production specification is few, and production cost is high, and cable weight is large, and not flexible, during installation, joint is many, takes up room large.
Fireproof cable in the market also exists the weak points such as cable length is limited, transition joint is not prevented fires, transport unwrapping wire difficulty, joint moisture-sensitive, difficulty of construction are large, and the cable laid also also exists a lot of hidden danger.Do not prevent fires for transition joint, how joint moisture-sensitive solves is the problem that at present reception solves.
utility model content:
In order to make up prior art problem, the weak points such as the purpose of this utility model is to provide a kind of with cutting off the high flame retardant flexible fire-proof cable of waterproof construction, and the cable length that effectively can solve cable is limited, transition joint is not prevented fires, transport unwrapping wire difficulty, joint moisture-sensitive, difficulty of construction are large.
The technical solution of the utility model is as follows:
With the high flame retardant flexible fire-proof cable cutting off waterproof construction, it is characterized in that, comprise three conductors, every root conductor is coated with mineral flame retardant coating outward all successively, silicone rubber insulation layer forms insulated wire cores, three mutual stranded bunchys of insulated wire cores form cable core, and cable core is through extrusion moulding in separator, and separator is coated with fire prevention lapping layer, be provided with metal separation sleeve spaced apart outside fire prevention lapping layer, metal separation sleeve is coated with low smoke halogen-free flame-retardant polyolefin external sheath layer.
The described high flame retardant flexible fire-proof cable with partition waterproof construction, is characterized in that, mineral flame retardant coating adopts the wrapped formation of synthetic mica tape, and the wrapped rate of putting up is not less than 28%.
The described high flame retardant flexible fire-proof cable with partition waterproof construction, it is characterized in that, metal separation sleeve spacer sleeve is contained in outside fire prevention twining package tape, and spacing is generally less than 3mm, the width of metal separation sleeve is generally not less than 5mm, and radial thickness is generally at 1.2 ~ 4.5mm.
The utility model has the advantages that:
The utility model is applicable in the power supply-distribution system of the high flame retardant requirement such as cable trough, cable shaft, tunnel, is specially adapted to the place that there are low cigarette, Halogen, flame-retardancy requirements in school, market, government organs etc., improves fireproofing of cable and joint humidity resistance.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
embodiment:
See accompanying drawing:
With the high flame retardant flexible fire-proof cable cutting off waterproof construction, comprise three conductors 1, every root conductor 1 is outer is coated with mineral flame retardant coating 2 all successively, silicone rubber insulation layer 3 forms insulated wire cores, silicone rubber insulation layer 3 has softness, heat radiation, the characteristic such as acid and alkali-resistance and corrosive gas, three mutual stranded bunchys of insulated wire cores form cable core, cable core through extrusion moulding in separator 4, separator 4 is coated with fire prevention lapping layer 5, metal separation sleeve 6 spaced apart is provided with outside fire prevention lapping layer 5, metal separation sleeve 6 is coated with low smoke halogen-free flame-retardant polyolefin external sheath layer 7, the low smoke halogen-free flame-retardant polyolefin extrusion molding of low smoke halogen-free flame-retardant polyolefin external sheath layer enters the gap between metal separation sleeve 6 and becomes to be integrated.
Mineral flame retardant coating 2 adopts the wrapped formation of synthetic mica tape, and the wrapped rate of putting up is not less than 28%, has the performances such as high temperature resistant, high insulation, ensures cable normal operation in high temperature environments.
Metal separation sleeve 6 spacer sleeve is contained in outside fire prevention twining package tape, and spacing is generally less than 3mm, and the width of metal separation sleeve 6 is generally not less than 5mm, and radial thickness is generally at 1.2 ~ 4.5mm.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each component part not clear and definite in the present embodiment is realized.
