Description

Antiradiation cable

Technical field

This utility model relates to cable technology, particularly relates to the technology of a kind of Antiradiation cable.

Background technology

Traditional cable has core, and the insulating barrier being coated on core outer peripheral face is constituted, traditional cable all uses design for conventional environment, the occasion being not suitable for having radioprotective uses, its reason is: in the occasion of radioprotective, insulating barrier can be caused damage by long radioprotective irradiation, thus affecting the transport properties of electric wire, affects the transmitting of signal. Therefore, when traditional cable uses in nuclear radiation environment, its service life is shorter.

Utility model content

For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of Antiradiation cable of long service life in nuclear radiation environment.

In order to solve above-mentioned technical problem, a kind of Antiradiation cable provided by the utility model, including at least one cable, described cable includes core, and it is coated on the insulating barrier of core outer peripheral face, it is characterised in that: also including the protecting pipe of energy Antiradiation, described cable is placed through in protecting pipe.

Further, described protecting pipe is lead pipe, or the metal pipe that lead tolerance is more than 80%.

Further, described cable also includes the screen layer of conduction, and described screen layer envelopes the outer peripheral face of insulating barrier.

Further, the spacing filler for limiting cable position it is filled with between described cable and protecting pipe.

Further, described spacing filler is one or more the mixture in industry butter, Colophonium, heavy oil, Carbon fibe, fluorofibre.

The Antiradiation cable that this utility model provides, protecting pipe can be effectively protected the cable in protecting pipe, being prevented effectively from the radioprotective impact on cable, it is thus possible to extend cable service life in nuclear radiation environment, suitable nuclear power station etc. have the occasion of radioprotective and use especially; Further, fill spacing filler at cable and protecting pipe and can be prevented effectively from cable play under external force, it is avoided that cable causes damage with protecting pipe because of phase mutual friction, the service life of cable can be extended further, and when selection has the industrial butter of moisture barrier properties, Colophonium, heavy oil as spacing filler, moreover it is possible to be prevented effectively from cable and make moist.
