The utility model discloses a high-voltage cable used in a power system. The outer surface of a metal core is coated with a polyesterimide paint film to form an insulated wire, and a group of the insulated wires are wrapped in a corona-resistant coating. The insulated wire and the corona-resistant coating are filled with a mica particle filling layer, and the corona-resistant coating is covered with an isolation protective sheath, and there is also a gap between the mica particle filling layer and the corona-resistant coating. There is an aluminum-plastic composite layer; the structure of the utility model is simple, and the polyesterimide paint film has strong high-voltage and high-temperature resistance, which can provide reliable guarantee for ultra-high-voltage power transmission in the power system. Corona-resistant coating, The triple insulation function of the mica particle filling layer and the isolation protective sleeve can effectively shield the high-intensity electromagnetic radiation generated by electric energy and prevent radiation leakage from endangering human health.
Description
Technical field
The utility model relates to a kind of cable, is specifically related to a kind of high pressure resistant cable.
Background technology
Cable is a kind of electric wire for transmission and distribution electric energy, and electric power system cable distribution commonly used is in the Urban Underground electrical network, the lead line in power station, the in-line power of industrial and mining enterprises and mistake river, cross the submarine transmission system in sea, in these systems, usually need cable to bear ultra high voltage and powerful electric energy, therefore common cable can't provide its specific withstand voltage properties, general solution is simple increase thickness of insulating layer, but the increase of thickness has affected the tack of insulation paint film, reduced the transmission performance of cable, simultaneously, the occasion that surpasses kilovolt high pressure at this kind, can produce the larger radiation of intensity in the transmitting procedure of electric energy, for a long time, affect the healthy of work of electric power system personnel.
The utility model content
Goal of the invention: for deficiency of the prior art, according to the high-tension cable for electric power system of a kind of anti-superhigh pressure and maskable radiation.
Technical scheme: a kind of high-tension cable for electric power system; outer surface at the metal core coats polyester-imide paint film formation insulated conductor; the fine and close free of pinholes of polyester-imide paint film; can be effectively high pressure resistant; one group of described insulated conductor is wrapped in anti-corona coating, in described insulated conductor and described anti-corona coating, is filled with the mica particle packed layer, prevents the corrosion of insulated conductor; while is electromagnetic radiation shielding effectively, described anti-corona coating outer cladding insulation blocking sleeve.
In order to strengthen the bending resistance tensile property of cable, also be provided with plastic-aluminum combined layer between described mica particle packed layer and described anti-corona coating, protect inner insulated conductor and mica particle packed layer not to be squeezed, increase the service life; Preferably, described plastic-aluminum combined layer is no less than 1 layer.
Concrete, the cross section of described metal core be circle or oval, for copper round wire or aluminium round wire is stranded forms, as the core component of electric energy transmitting.
Preferably, described insulation blocking sleeve is the ethylene-propylene rubber layer, and it is wear-resisting withstand voltage and have stable insulation property, guarantees that whole cable can work under adverse circumstances.
Beneficial effect: of the present utility model simple in structure; high pressure resistant and the resistance to elevated temperatures of polyester-imide paint film is extremely strong; the superhigh pressure electric energy transmission can be in electric power system provides reliable guarantee; triple insulation functions of anti-corona coating, mica particle packed layer and insulation blocking sleeve; can effectively shield the high-intensity electromagnetic radiation that electric energy produces, prevent from that radiation from leaking to be detrimental to health.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below technical solutions of the utility model are elaborated, but protection range of the present utility model is not limited to described embodiment.
embodiment:as shown in Figure 1, a kind of high-tension cable for electric power system, outer surface at metal core 1 coats polyester-imide paint film 2 formation insulated conductors, metal core 1 forms for copper round wire is stranded, cross section is circular, the fine and close free of pinholes of polyester-imide paint film 2, can be effectively high pressure resistant, 4 insulated conductors are wrapped in anti-corona coating 5, be filled with mica particle packed layer 3 in insulated conductor and anti-corona coating 5, effective electromagnetic radiation shielding when preventing the corrosion of insulated conductor, also be provided with the plastic-aluminum combined layer 4 of one deck between mica particle packed layer 3 and anti-corona coating 5, the protection internal structure is indeformable, anti-corona coating 5 outer cladding insulation blocking sleeves 6, concrete, insulation blocking sleeve 6 is the ethylene-propylene rubber layer, there is stable wear-resisting withstand voltage properties.
