The utility model discloses a high current-carrying capacity low conduction temperature fireproof electric power flexible cable for accident net analysis. The high current-carrying capacity low conduction temperature fireproof electric power flexible cable for accident net analysis comprises three copper conductors, wherein outer surfaces of the copper conductors are coated with fireproof insulating layers, the three copper conductors are intertwisted to form a cable core, a ceramic combined band is wound around an outer surface of the cable core, an outer surface of the ceramic combined band is coated with a high thermal resistance polyolefin protection sleeve layer, each copper conductor is formed by intertwisting multiple copper wires, the pitch diameter ratio of the cable formed by the three copper conductors is 8 to 12 mm, and a pace between the fireproof insulating layer and the ceramic combined band is filled with multiple glass fiber filaments. The high current-carrying capacity low conduction temperature fireproof electric power flexible cable for accident net analysis is advantageous in that diameters of the copper conductors are reduced, a large amount of heat generated by insulation can be blocked in the cable core, dynamic balance is realized in the cable core, and therefore that temperature on a surface of the protection sleeve layer does not exceed 70 DEG C can be guaranteed.

Description

The accident net is analyzed with the fire-resistant flexible electric power cable of high current-carrying capacity low conduction temperature
Technical field
The utility model relates to the fire-resistant power cables of high current-carrying capacity, also relates to this accident net and analyzes with the fire-resistant flexible electric power cable of high current-carrying capacity low conduction temperature.
Background technology
In the ocean engineering field, engineering field, island, especially have the field, naval vessel of national defence purposes, all be furnished with the accident net electric energy transmitting of emergency start when having an accident, to ensure the electric power transfer of relevant device.At present, what such cable used all is fire-retardant class cables, and that specification is approximately used is 3*70, and external diameter is greatly about about 40.0mm, ampacity is about 150A, because temperature requirement is very strict, because after emergency takes place, need cable be hauled out reel with hand, and the insertion related system, temperature is too high, and hand is taken incessantly, and the jacket surface temperature does not allow above 70 ℃.
How specification is changed into 3*25, and ampacity is same requires to reach 150A, the same requirement of jacket surface temperature is no more than 70 ℃, and realization accident net cable changes fire safe type into by flame retardant type, have very large technological development difficulty, because (1) ampacity is constant, specification is by 70mm 2Reduce to 25mm 2The time, conductor heating can obviously strengthen, and when 50 ℃ of operating ambient temperatures, also can substantially exceed when reaching the temperature of jacket surface 70 ℃ (we do overtesting with common cable, and temperature is finally at 108 ℃); (2) the cable specification reduces at double, and the outside diameter of cable requires to reduce, and current-carrying capacity of cable and jacket surface are temperature-resistant, also require cable to possess fire-resistant function simultaneously, and this is very difficult concerning the realization of cable.
Summary of the invention
The purpose of this utility model provides a kind of accident net and analyzes with the fire-resistant flexible electric power cable of high current-carrying capacity low conduction temperature, when 50 ℃ of operating ambient temperatures, reduced the copper conductor diameter, realized a large amount of heats that insulation produces to be locked in the cable core class simultaneously, reach dynamic equilibrium in cable core inside, thereby guaranteed that the restrictive coating surface temperature is no more than 70 ℃.
For achieving the above object, the technical solution adopted in the utility model is: a kind of accident net is analyzed with the fire-resistant flexible electric power cable of high current-carrying capacity low conduction temperature, comprise three copper conductors, this copper conductor outer surface is coated with refractory insulating layer, three stranded formation one cable cores of copper conductor, one potteryization composite band is wrapped in described cable core outer surface, and a high thermal resistance polyolefin jacket layer is coated on described potteryization composite band outer surface, and described copper conductor is by some stranded the forming of copper wire; The lay ratio of described three copper conductor strandings is 8~12mm; Be filled with some glass fibers between described refractory insulating layer and the potteryization composite band.
Further improved technical scheme is as follows in the technique scheme:
1. in the such scheme, the lay ratio of copper wire stranding is 12~14mm in the described copper conductor.
2. in the such scheme, the sectional area of described copper conductor is 16~240mm 2
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The utility model accident net is analyzed with the fire-resistant flexible electric power cable of high current-carrying capacity low conduction temperature, its copper conductor outer surface is coated with refractory insulating layer, three stranded formation one cable cores of copper conductor, one potteryization composite band is wrapped in described cable core outer surface, one high thermal resistance polyolefin jacket layer is coated on described potteryization composite band outer surface, described copper conductor is by some stranded the forming of copper wire, and the lay ratio of three copper conductor strandings is 8~12mm; Make that this cable specification number demultiplication is little, ampacity is constant when still being decreased to 30mm and being diminished by 40mm for 150A, external diameter, under 50 ℃ of operating ambient temperatures, the jacket surface temperature is no more than 70 ℃, requirement in the complete conformance with standard of every performance of cable simultaneously, and make cable possess fire-retardant and fire resistance simultaneously; Secondly, be filled with some glass fibers between its refractory insulating layer and the potteryization composite band, further reduced fire-resistant flexible electric power cable surface temperature, thereby improved the cable operating time.
