Abstract
The invention discloses an anti-radiation cable, which comprises a plurality of conductors. A branch insulated layer is arranged outside each conductor; a total insulated layer is arranged outside the branch insulated layers; a shielding layer is arranged outside the total insulated layer; a steel strip wrapping layer is arranged outside the shielding layer; and a sheath layer is arranged outside the steel strip wrapping layer. According to the anti-radiation cable, the structure is simple, the manufacturing is convenient, the anti-radiation performances are good, cable transmission signals can be prevented from being disturbed, and the service life of the cable is improved.
Description
Technical field
The present invention relates to cable technology field, relate in particular to a kind of radiation proof cable.
Background technology
Nuclear power station environment for use requires cable to have high shielding property, and normal cable does not have this performance, can not be applied in the equipment of nuclear power station, therefore, can be applied in nuclear power station in the urgent need to developing a kind of cable.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of radiation proof cable with good shielding property.
For achieving the above object, the invention provides following technical scheme: a kind of radiation proof cable, comprise several conductors, be provided with a point insulating barrier outward at conductor, be provided with total insulating barrier outward at a point insulating barrier, described total insulating barrier is provided with screen outward, and described screen is provided with steel band lapping layer outward, and described steel band lapping layer is provided with restrictive coating outward.
Preferably, between described point of insulating barrier and total insulating barrier, be provided with a ground wire.
Preferably, described steel band lapping layer is the wrapped armour in biobelt gap.
Preferably, described screen forms by thin copper wire is wrapped.
Adopt the beneficial effect of above technical scheme to be: the present invention is simple in structure, easy to make, and shielding property is better, prevent that cable transmission signal is interfered, improve cable useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein, 1-conductor, 2-point insulating barrier, 3-total insulating barrier, 4-screen, 5-steel band lapping layer, 6-restrictive coating, 7-ground wire.
Embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and accompanying drawing, the invention will be further described, and this embodiment only, for explaining the present invention, does not form limiting the scope of the present invention.
Fig. 1 has shown the execution mode of a kind of radiation proof cable of the present invention: a kind of radiation proof cable, comprise several conductors 1, outside conductor 1, be provided with point insulating barrier 2, outside point insulating barrier 2, be provided with 3 layers of total insulation, outside total insulating barrier 3, be provided with screen 4, outside screen 4, be provided with steel band lapping layer 5, outside steel band lapping layer 5, be provided with restrictive coating 6, steel band lapping layer 5 is the wrapped armour in biobelt gap, between point insulating barrier 2 and total insulating barrier 3, is provided with a ground wire 7, and screen 7 forms by thin copper wire is wrapped.
Adopt the beneficial effect of above technical scheme to be: the present invention is simple in structure, easy to make, and shielding property is better, prevent that cable transmission signal is interfered, improve cable useful life.
The above is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
