Description
Technical field
The utility model is related to cables, specifically core grade cable for ship.
Background technology
At present, the cable used on offshore platform and ship is cable for ship, such cable presses IEC60092-353 standards
Design and manufacture, non-refractory cable is made of tinned copper conductor, insulating layer, belting layer, filling and oversheath, have low cigarette,
Halogen, fire-retardant and good salt spray resistance, acid and alkali-resistance and bear the performances such as A classes are fire-retardant.
The land safety-related cable of Nuclear Power Station is nuclear grade cable, such cable is fire-retardant etc. except Halogen, low cigarette, low toxicity, B classes
It is required that it is outer, also there are corresponding requirements to cable life, heat resistance, chemical stability, radiation-resistant property (K1 and K2 classes) etc., at present should
Class cable is mainly made of conductor, conductor shielding, interior insulation, insulation shielding, copper strip shielding, filling, band, oversheath.
Cable used in packaged type nuclear power station waterborne, the A classes that should meet cable for ship are fire-retardant, insulating materials is tried without cracking
The requirement of time etc. is tested, also to meet requirement of the nuclear grade cable to service life, resistance to irradiation (K1, K2 cable) etc., it is existing
Cable can not meet above-mentioned requirements simultaneously.Therefore, Waterborne movable platform and nuclear device needs can be met simultaneously by designing
And the core grade cable for ship of service life length is very necessary.
Utility model content
The purpose of this utility model is to provide one kind and can meet Waterborne movable platform and nuclear device needs simultaneously and make
With the core grade cable for ship of long lifespan.
To achieve the above object, the utility model adopts the following technical solution：One seed nucleus grade cable for ship, including outer shield
Set, inner sheath and cored wire, it is characterized in that inner sheath is arranged in oversheath, are provided with the first band between inner sheath and oversheath
Layer, the cored wire of one or more is provided in inner sheath, and cored wire includes conductor and set gradually from inside to outside along the radial direction of conductor
The inner insulating layer being halogen-free, the external insulation layer being halogen-free, the second belting layer, metal screen layer and oxygen barrier layer, cored wire with
Filler is provided in the space that inner sheath is formed, oversheath and inner sheath are the insulating sheath being halogen-free.
Further, the conductor is copper wire or tinned wird, and the metal screen layer is copper strip shielding layer.
The utility model is set using interior insulation and external insulation is provided on each cored wire of cable outside external insulation layer
There is band, band is provided outside copper strip shielding layer and oxygen barrier layer, can both extend the service life of cable, also ensures the resistance to environment of cable
Performance.The utility model can meet Waterborne movable platform and nuclear device needs simultaneously.

Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments, but the embodiment should not be construed as pair
The limitation of the utility model.
Seed nucleus grade cable for ship as depicted, including oversheath 1, inner sheath 2 and cored wire 3, inner sheath 2 is arranged on outer
In sheath 1, the first belting layer 4 is provided between inner sheath 2 and oversheath 1, the cored wire 3 of one or more is provided in inner sheath 2,
Cored wire 3 includes conductor 3.1 and the inner insulating layer 3.2 being halogen-free, no that sets gradually from inside to outside of radial direction along conductor 3.1
Halogen-containing external insulation layer 3.3, the second belting layer 3.4, metal screen layer 3.5 and oxygen barrier layer 3.6, cored wire 3 and 2 shapes of inner sheath
Into space in be provided with filler 5, oversheath 1 and inner sheath 2 are the insulating sheath being halogen-free.
Preferred embodiment is：In said program, the conductor 3.1 be copper wire or tinned wird, the metallic shield
Layer 3.5 is copper strip shielding layer.
The content not being described in detail in this specification belongs to the prior art well known to those skilled in the art.
