Description
Technical field
The utility model relates to a kind of novel protective-cover type flame retardant cable, belongs to cable machinery technical field.
Background technology
At present along with the raising of power supply grid electric pressure and the energy consumption of power consumption equipment increase, therefore current cable is caused operationally, need to possess good insulation property, good heat resistance, her large wire diameter cable is separately needed to possess lower kelvin effect, simultaneously, the occasion used due to cable has great otherness, thus cause cable very easily to receive the threat such as external impacts or pollutant corrosion, therefore require that cable has good damage-retardation performance simultaneously, in order to meet this requirement, currently have developed polytype construction of cable, but in use find, the current construction of cable often only can meet to cable use required for possess high temperature resistant, insulation, tension, resistance to compression, in numerous characteristic such as fire-retardant one or several, the all characteristics possessed required for cable use cannot be met completely, therefore cause the serviceability stability of cable not enough, and the scope of application, especially relatively weak to the adaptability of environment, and the scope of application that therefore result in cable is greatly limited, effectively cannot meet the actual needs used, therefore for this present situation, in the urgent need to developing a kind of novel protective-cover type flame retardant cable, to meet the needs that current reality uses.
Utility model content
This novel object is just to overcome above-mentioned deficiency, provides a kind of novel protective-cover type flame retardant cable.
For achieving the above object, this is novel is be achieved through the following technical solutions:
A kind of novel protective-cover type flame retardant cable, comprise conductor wire core, inner insulation layer, flexible sheathing tube, hard protecting pipe, thermal insulation layer, mica tape insulating barrier, shielding protection layer, magnesia powder insulating barrier and external insulation layer, wherein conductor wire core at least two, and it is coated by inner insulation layer, each conductor wire core is coated by hard protecting pipe, and each conductor wire core is uniform around hard protecting pipe axis, and distribute with hard protecting pipe axis being parallel, primary insulation interlayer outside hard protecting pipe and conductor wire core is filled by magnesia powder insulating barrier, mica tape insulating barrier at least one deck be coated on hard protecting pipe outer surface, hard protecting pipe outer surface uniform stress groove, flexible sheathing tube is coated on outside mica tape insulating barrier, external insulation layer is coated on outside mica tape insulating barrier, described shielding protection layer and thermal insulation layer are all between external insulation layer and mica tape insulating barrier.
Further, described conductor wire core is single metal wire or rope-lay strand structure.
Further, described stress separation is 0.5-5 centimetres, 1/2 of the little and hard protecting pipe pipe thickness of the degree of depth.
Further, the hard protecting pipe tube wall between described adjacent stress groove is cydariform.
The utility model is rationally distributed, insulating properties, heat-resisting quantity, corrosion resistance and fire resistance are good, and the kelvin effect that can effectively reduce when cable runs, thus effectively reduce cable operating temperature and electric energy loss, separately there is good tension, resistance to compression and anti-sagging ability simultaneously, thus greatly improve safety in utilization and the reliability of cable, and effectively raise the place adaptive capacity of cable.
