Description
Technical field:
The utility model relates to a kind of rated voltage 450/750V mineral-insulated fireproof type power cable, belongs to technical field of electric wires and cables.
Background technology:
Along with improving constantly of expanding economy and the people's living standard, people's awareness of safety is also being deepened gradually.Nowadays, be accompanied by the expansion of national Urbanization Construction, building trade has welcome again spring one time; Add taking place frequently of fire disaster accident in recent years, this wherein greatly fire be attributed to the aging of electrical system and cause, people start more and more to recognize the importance of Building Fire Protection.Therefore, China's electric wire manufacturing enterprise developed flame retardant cable in succession in recent years, low smoke and low halogen cable, and low-smoke halogen-free inflaming-retarding cable, high flame-retardant cable, fire-resisting cable etc. are dealt with the market demand.
The manufacture of the fireproof cable of China at present is also in the primary stage, adds that the technical merit of domestic each cable producer and level of processing are uneven, adds general fireproof cable and adopts magnesium oxide as insulation system more.Although its fire protecting performance is desirable, because manufacturing process is too complicated, to reasons such as equipment requirement height, cause its selling at exorbitant prices, thereby market acceptance level is low.
Summary of the invention:
For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of rated voltage 450/750V mineral-insulated fireproof type power cable, there is excellent fire prevention, oil resistant, anticorrosion, Halogen, high flame retardant, the characteristic such as block water, can be widely used in the fields such as building.
The utility model technical solution problem adopts following technical scheme:
Rated voltage 450/750V mineral-insulated fireproof type power cable, by multiply tinned copper conductor and the synthetic mica tape fireprotection layer that extrudes on conductor, form insulated wire cores, by many described insulated wire cores, be twisted into cable core, the packed layer that cable core gap-fill consists of glass cord, outside described cable core, the overlapping fire-resistant composite band of ceramic, the chain armouring copper sheath of being surrounded with is as inner sheath and screen, and the outermost layer of cable is extruded with oversheath.
Described synthetic mica tape fireprotection layer forms the insulating barrier of cable, and the fire-resistant composite band of described ceramic forms the stranding band of cable conductor.
The oversheath of described cable is thermosetting halogen-free and low-smoke flame-retardant polyolefin oversheath.
In the lapping structure of described fireprotection layer, the vertical bag of innermost layer mica tape, outer mica tape is put up wrapped, and adjacent layer, around on the contrary, increases Cable Bending Radius.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the stranded tinned copper conductor structure of the utility model conductor, has improved the Corrosion Protection of control cables greatly, guarantees that cable keeps excellent electric property in running simultaneously.
2, it is wrapped that the utility model fireprotection layer adopts synthetic mica tape, and its temperature resistant grade reaches 1000 ℃, and, under 1000 ℃ of flame conditions, cable can normally move 90 minutes, guarantees the normal operation of various control system, reduces unnecessary loss.And require the vertical bag of innermost layer mica tape, outer mica tape is put up wrapped, and adjacent layer, around on the contrary, increases Cable Bending Radius.
3, in the utility model, adopt 125 ℃ of IXPE oversheaths after electron irradiation is crosslinked, mechanical performance improves greatly, guarantees that cable has excellent mechanical performance.Serviceability temperature reaches 125 ℃ simultaneously, compares with general control cable, and rise appreciably useful life.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Number in the figure: 1 conductor, 2 fireprotection layers, 3 packed layers, 4 composite band, 5 copper sheaths, 6 oversheaths.
Below pass through embodiment, and the utility model is described in further detail by reference to the accompanying drawings.
Embodiment:
Embodiment: in conjunction with Fig. 1, the rated voltage 450/750V mineral-insulated fireproof type power cable of the present embodiment, by 7 strands of tinned copper conductors 1, stranded and wrapped synthetic mica tape fireprotection layer 2 on conductor forms insulated wire cores, by three insulated wire cores, be twisted into cable core, the packed layer 3 that cable core gap-fill consists of halogen-free flameproof high-temperature glass fibre rope, the outer fire-resistant composite band 4 of overlapping wrapped ceramic of cable core, compacting wrinkle copper sheath 5 is as inner sheath and screen, extrude thermosetting halogen-free and low-smoke flame-retardant polyolefin oversheath 6, carry out electron irradiation.Wherein, synthetic mica tape fireprotection layer forms the insulating barrier of cable, and the fire-resistant composite band 4 of ceramic forms the stranding band of cable conductor.The oversheath of cable is thermosetting halogen-free and low-smoke flame-retardant polyolefin oversheath.In specifically arranging, in the lapping structure of fireprotection layer, the vertical bag of innermost layer mica tape, outer mica tape is put up wrapped, and adjacent layer, around on the contrary, increases Cable Bending Radius.
In concrete enforcement, corresponding structure setting and material are selected to be respectively:
Conductor 1 is to adopt tin-coated copper skein silk system to form, and conductor layer any surface finish, scrapes to injure come off without burr, Wuxi layer;
Fireprotection layer 2 adopts innermost layer for vertical bag, and skin determines that according to different size the number of plies adopts synthetic mica tape overlapping wrapped, and the wrapped rate of putting up is not less than 40%;
Packed layer 3 adopts halogen-free flameproof high-temperature glass fibre rope, fills closely knit, rounding;
Lapping layer is overlapping wrapped in cable core outside by the fire-resistant composite band 4 of ceramic;
Chain armouring copper sheath 5 adopts the compacting of annealing oxygen-free copper stripe;
Oversheath 6 adopts and extrudes thermosetting halogen-free and low-smoke flame-retardant polyolefin, and it is crosslinked to carry out electron irradiation.
