Abstract
本实用新型公开了一种矿物绝缘防火软电缆，其特征是，主线芯导体(1a)和地线芯导体(1b)由多股软铜线绞合形成，在所述的主线芯导体(1a)和地线芯导体(1b)上分别绕包四层云母带后再纵包一层铜带并通过连续无缝焊接形成主线芯绝缘层(2a)和地线芯绝缘层(2b)，包覆有绝缘层的主线芯导体和地线芯导体绞合成缆构成缆芯；在所述的缆芯外，通过绕包两层云母带形成包带层(3)，在包带层外用铜带纵包并通过连续无缝焊接构成外护套层(4)；在外护套层外再挤包一层塑料保护层(5)。本实用新型适用于要求具有耐火特性的各种场所。
The utility model discloses a mineral insulated fireproof flexible cable, which is characterized in that the main core conductor (1a) and the ground core conductor (1b) are formed by stranding soft copper wires, and the main core conductor (1a) ) and the ground core conductor (1b) are respectively wrapped with four layers of mica tape, and then a layer of copper tape is longitudinally wrapped, and the main core insulation layer (2a) and the ground core insulation layer (2b) are formed by continuous seamless welding. The main core conductor covered with an insulating layer and the ground core conductor are twisted into a cable to form a cable core; outside the cable core, a tape layer (3) is formed by wrapping two layers of mica tape, and a copper tape is used outside the tape layer The outer sheath layer (4) is formed longitudinally and through continuous seamless welding; and a plastic protective layer (5) is extruded outside the outer sheath layer. The utility model is suitable for various places requiring fire resistance.
Description
Technical field
The utility model relates to a kind of mineral insulated cable, relates in particular to a kind of mineral insulation fire prevention flexible cable, belongs to technical field of electric wires and cables.
Background technology
At present; No matter be commercial power or household electricity, people also more and more pay attention to the fail safe of electricity consumption, and all kinds of fire-resisting cables begin to be widely used in fields of society; A power utilization system such as skyscraper, subway, airport, also increasingly high to the fire resistance requirement of cable.And that the common fire-resisting cable of general class exists is fire-retardant, fire resistance is low, quality is heavy, can't satisfy shortcomings such as fire resistance rating height, does not meet the specific (special) requirements of above-mentioned occasion.
The utility model content
The utility model is the weak point for avoiding above-mentioned prior art to exist; A kind of have anti-tampering, environmental protection, fire-retardant, fire-resistant, safety are provided, have light in structure, long service life simultaneously, can guarantee the mineral insulation fire prevention flexible cable of advantages such as personal safety.
The utility model mineral insulation fire prevention flexible cable; Its design feature is; Master core conductor and ground wire core conductor form by the multiply annealed copper wire is stranded; Vertical again bag one deck can weld copper strips and form master core insulating barrier and ground wire core insulation layer behind wrapped respectively four stratus master tapes on described master core conductor and the ground wire core conductor, and the master core conductor and the stranded stranding of ground wire core conductor that are coated with insulating barrier constitute cable core; Outside described cable core, form belting layer through wrapped two-layer mica tape, constitute external sheath layer in the vertical bag of belting layer external application copper strips back through the continuous seamless welding; Outside external sheath layer, extrude one deck plastic protective layer again.
Compared with present technology, the beneficial effect of the utility model is embodied in:
1, the utility model core conductor adopts the stranded formation of multiply annealed copper wire; Make the cable softness good; The copper strips that outside core and cable core, is surrounded with no seam welding respectively is as sheath; Not only improved performances such as whole cable fire prevention, waterproof, anti-interference, anti-mechanical damage, and it is inner to prevent that imflammable gas, oily vapour, flame from getting into cable, also is of value to the production electric cable with large cross-section simultaneously.
2, the utility model cable adopts copper strips insulation and sheath, guarantees the cable loop guaranteed cost, and cable does not puncture more than in working temperature reaches 1000 ℃ environment, using 90min.
3, the utility model cable jacket has increased low smoke and zero halogen cross-linked polyolefin material outward and has done the cable external protection, has prolonged the useful life of cable.
Description of drawings
Fig. 1 is the utility model structural representation.
Serve as theme core conductor, 1b of label among the figure: 1a is that serve as theme core insulation layer, 2b of ground wire core conductor, 2a is that ground wire core insulation layer, 3 is protective layer for external sheath layer, 5 for belting layer, 4.
Below, the utility model is described further in conjunction with accompanying drawing through embodiment.
Embodiment
Referring to Fig. 1; In the present embodiment; Master core conductor 1a and ground wire core conductor 1b form by the multiply annealed copper wire is stranded, are indulging the copper-clad band and are forming master core insulating barrier 2a and ground wire core insulation layer 2b through seamless welding manner behind the wrapped four stratus master tapes respectively on master core conductor 1a and the ground wire core conductor 1b; The master core conductor 1a and the ground wire core conductor 1b that are coated with insulating barrier twist together stranding formation cable core; Outside cable core, wrapped two stratus master tapes constitute belting layer 3, and vertical copper-clad band forms external sheath layer 4 through seamless welding manner outside belting layer, on oversheath, add one deck plastic sheath and form protective layer 5.
