Abstract
The utility model relates to a power cable. The power cable comprises a plurality of wire cores. The wire core comprises a conductor and an insulating layer wrapped around the conductor. The wire cores are wrapped in an inner sheath layer. Flame-retardant material is filled between the inner sheath layer and the wire cores. Multiple heat dissipating holes are disposed in the flame-retardant material along the radial direction of the flame-retardant material. The inner sheath layer is wrapped in a shielding layer. The shielding layer is wrapped in a heat isolating layer. The heat isolating layer is wrapped in a reinforcing layer. The reinforcing layer is wrapped in a sheath. The power cable has characteristics of high conductivity, good flame resistance, good corrosion resistance, and good anti-interference performance, can be widely used in severe environment such as high temperature and corrosion prevention environments, and has high practicality, economical efficiency, and durability.
Description
Technical field
The utility model relates to a kind of power cable.
Background technology
Along with fast development of national economy, as the electric wire of national economy " sustainer ", its consumption and the scope of application are increasing.Present raising along with all trades and professions automaticity, originally can not satisfy present specification requirement as the used plain edition cable of transferring electric power, at high temperature, under the complicated condition of severe such as high corrosion, lack the power cable of the excellent combination property with broad applicability.
The utility model content
The purpose of this utility model provides a kind of power cable that can all can keep excellent properties under the abominable situation of multiple complexity, to overcome at present existing power cable above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of power cable comprises some cores, and described core comprises conductor and be coated on the insulating barrier in the conductor outside that the described core outside is coated with sheath, is filled with fire proofing between sheath and the core, radially is provided with a plurality of louvres in the fire proofing; The described sheath outside is coated with screen, and the screen outside is provided with thermal insulation layer, and the thermal insulation layer outside is provided with reinforced layer, and the reinforced layer outside is provided with sheath.
Preferably, described louvre number is identical with number of conductor.
Preferably, described fire proofing is the Halogen insulating material; Described screen is aluminium-plastic tape; Described reinforced layer is establishment glass fiber sheath.
Preferably, described sheath material is silicon rubber.
The beneficial effects of the utility model are: the utlity model has the electric conductivity height, characteristics such as anti-flammability, corrosion resistance, anti-interference are good can be widely used in adverse circumstances such as high-temperature anticorrosion, have advantages of high practicability, economy and durability.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of the described power cable of the utility model embodiment.
Among the figure:
1, core; 2, conductor; 3, insulating barrier; 4, sheath; 5, fire proofing; 6, louvre; 7, screen; 8, thermal insulation layer; 9, reinforced layer; 10, sheath.
Embodiment
As shown in Figure 1, the described power cable of the utility model embodiment, comprise some cores 1, described core 1 comprises conductor 2 and is coated on the insulating barrier 3 in conductor 2 outsides, described core 1 outside is coated with sheath 4, be filled with fire proofing 5 between sheath 4 and the core 1, radially be provided with a plurality of louvres 6 in the fire proofing 5; Described sheath 4 outsides are coated with screen 7, and screen 7 outsides are provided with thermal insulation layer 8, and thermal insulation layer 8 outsides are provided with reinforced layer 9, and reinforced layer 9 outsides are provided with sheath 10, and described fire proofing 5 is the Halogen insulating material, and described louvre 6 numbers are identical with conductor 2 numbers; Described screen 7 is aluminium-plastic tape, and described reinforced layer 9 is establishment glass fiber sheath, and described sheath 10 materials are silicon rubber.
During concrete the use, louvre 6 is radially evenly offered in fire proofing 5 inside, and conductor 2 is better dispelled the heat by louvre 6, reduced the utilization rate of filler simultaneously, reduced production cost, and bittern-free flame-proof material fire resistance excellence, resistance to chemical corrosion is good.Thermal insulation layer 8 prevents the moment high temperature core of burning, and reinforced layer 9 protection cables are not subjected to the mechanical external force effect, and screen 7 is mainly used in guaranteeing the stability of cable, and it is little to reach the shielding rejection coefficient, and the strong effect of anti-strong electromagnetic ability is guaranteed the accuracy of electric energy transmitting.Sheath 10 adopts silicon rubber, avoided the relatively poor shortcoming of sheath 10 environmental stress crack resistances of fluoroplastics, can completely cut off moisture, chemical substance to the erosion of cable, and not having pernicious gas during the silicon rubber high-temp combustion emits and is beneficial to environmental protection, the silica product that generates is attached on the core 1, also can stop flame to the intrusion of core 1.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection range of the present utility model.
