Abstract
The invention relates to a ceramic fireproof flexible cable. The ceramic fireproof flexible cable comprises conductors, wherein an insulating layer is arranged outside each conductor, a ceramic fireproof protecting layer is arranged outside each insulating layer, a filling layer is arranged outside the ceramic fireproof protecting layers, a heat insulation lining is arranged outside the filling layer, and a metal sheath layer is arranged outside the heat insulation lining. The ceramic fireproof flexible cable is good in fireproof effect, flexible, good in insulating effect, free of moisture absorption and convenient and easy to construct and install, and continuous mechanical production can be achieved.
Description
Technical field
The present invention relates to a kind of cable, be specifically related to a kind of ceramic cable.
Background technology
Along with the fast development of national economy, as the aortal electric wire of national economy, its consumption and the scope of application increasing.In recent years, the industries such as power plant, transformer station, smelting and petrochemical industry, very big to the demand of cable.
TC-YTTW metal sheath inorganic mineral insulation cable and BTTZ magnesium oxide mineral insulation cable belong to the category of mineral insulated cable (fireproof cable).Although BTTZ magnesium oxide mineral insulation cable production history is longer, although existing production line transform to some extent, upgrade, product structure never upgrades, and manufacturing process falls behind complicated.Its conductor adopts real core copper bar, and sheath is drawing copper tubes, and therefore, cable is rigidity.Insulating material adopts the easy moisture absorption of magnesium oxide (Mgo) powder, brings a lot of difficulty to the making of installation and terminal.Because oversheath adopts drawing copper tubes to form, produce drum length of cable limited (just there is this problem in theory), in order to meet actual operation requirements, more nonfireproof transition joint just must be increased in cable line, not only add the extra charge of transition joint but also do not reach fireproof requirement, also create unnecessary contact resistance in the loop, thus greatly reduce the efficiency of transmission of electricity, add the potential faults point of transmission of electricity.
Summary of the invention
Goal of the invention: the object of the invention is, in order to overcome deficiency of the prior art, to provide a kind of flameproof effect good, cable is soft, mechanization continuous seepage can be realized, insulation effect is good, nonhygroscopic, construction install convenience simple ceramic fireproof type flexible cable.
Technical scheme: in order to solve the problems of the technologies described above; a kind of ceramic fireproof type flexible cable of the present invention; it comprises conductor; insulating barrier is provided with in described conductor outside; ceramic fireproof jointing sheath is provided with in described insulating barrier outside; be provided with packed layer in described ceramic fireproof jointing sheath outside, be provided with insulation lining in described packed layer outside, be provided with metal sheath layer in described insulation lining outside.
Nonmetal jacket layer is provided with in described metal sheath layer outside.
Described conductor is four.
Described conductor is copper conductor, and forms by strand copper wire is stranded.
Described packed layer is composite material of silicon carbide packed layer or alkali-free glass rope packed layer.
The thickness of described insulating barrier is between 0.7-2.0mm.
The thickness of described insulation lining is 0.4mm.
The thickness of described metal sheath layer is between 0.5-1.0mm.
The thickness of described nonmetal jacket layer is between 2.0-3.4mm.
Ceramic fireproof jointing sheath of the present invention, with the high-molecular organic material of " revolutionary character ", namely ceramic fireproof silicon rubber and high temperature resistance glass fiber cloth are that base material prolongs pressure and is composited, and they start hardening housing of forming ceramic-like more than 350 DEG C at temperature.The housing that " ceramic " is hard in case of fire can play the effect of well fire-retardant, fire-resistant, fire prevention, fire insulation, reaches as high as 3000 DEG C, effective guarantee circuit unimpeded.Be mainly used in the fireproof layer that alternative mica tape does electric wire, also can do insulating barrier simultaneously, be widely used in production high, medium and low voltage fire-resistant wire and cable, flexible fire-proof cable, naval vessel cable and mining cable etc.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: overall structure of the present invention is simple, adopt ceramic fireproof jointing sheath, play well fire-retardant, fire-resistant, fire prevention, the effect of fire insulation, adopt that strand copper wire is stranded forms described conductor, overall flexibility can be ensured, adopt insulation lining, flame retardant effect can be played further, adopt metal sheath layer and nonmetal jacket layer, can ensure overall survivable, this product can realize mechanization continuous seepage, insulation effect is good, nonhygroscopic, construction install convenience is simple, realistic instructions for use.
