Description
Technical field
This utility model is related to a kind of cable for nuclear power station.
Background technology
A kind of special cable is needed in Nuclear Power Station, the special cable is used for the reactor building of nuclear instrument system
Neutron detector and rosette and penetration piece, the signal between auxiliary plant penetration piece and preamplifier and signal processing rack
Transmission.Due to special, the performance of this cable of needs with steady operation under normal and abnormal conditions of environment described in the cable.
Utility model content
In order to solve problem present in background technology, this utility model provides a kind of four coaxial electrical of used in nuclear power station 1E levels
Cable, the cable can keep electric property and physical property during normal, exception and accident occur.
To reach above-mentioned purpose, this utility model is adopted the following technical scheme that：
A kind of four coaxial cable of used in nuclear power station 1E levels, it is characterised in that including conductor cores, conductor cores periphery is extruded with first
Insulating barrier and the second insulating barrier, are woven with internal shield outside the second insulating barrier, be extruded with inner sheath, outside inner sheath outside internal shield
External shielding layer is woven with, restrictive coating outside external shielding layer, is extruded with, metal bellowss outside restrictive coating, are provided with, is squeezed outside metal bellowss
It is surrounded by oversheath.
The conductor cores are tinned copper conductor.
Cross-linked ethylene of first insulating layer material for irradiation.
Second insulating layer material is radiation hardness fire proofing.
Internal shield and external shielding layer are all formed by tinned copper wire braiding.
The material of inner sheath, restrictive coating and oversheath is cross-linking radiation polyolefin.
The beneficial effects of the utility model are：
(1) cable has fire-retardant, low cigarette, Halogen and anti-flooding characteristic；
(2) four coaxial cables of reactor building are during normal, exception and design basis accident occur and after generation
Electric property and physical property should be able to be kept.
(3) four coaxial cables should also meet water logging 8m under design basis accident operating mode, continue to still ensure which in 4 months
Electric property and physical characteristics.
Description of the drawings
Below in conjunction with the accompanying drawings this utility model is further illustrated
Fig. 1 is the structural representation of four coaxial cable described in the utility model；
Specific embodiment
