Abstract
The invention discloses a double-shielding cable for nuclear power. The double-shielding cable comprises an inner conductor. An inner insulating layer is wrapped on the outer side of the inner conductor. An inner shielding layer is wrapped on the outer side of the inner insulating layer. An outer insulating layer is wrapped on the outer side of the inner shielding layer. An outer shielding layer is wrapped on the outer side of the outer insulating layer. The double-shielding cable has the advantages that the double-shielding cable is high-radiation-resistant, high-temperature-resistant, high in mechanical strength, high in reliability, wear-resistant and oil-resistant.
Description
Technical field
The present invention relates to the radio communication technical field, specifically is a kind of nuclear power screened cable.
Background technology
China's third generation nuclear power station is mainly still based on pressure water reactor, and the basic security principle of pressure water reactor then is lifelong defence and single standard criterion.Under the constant situation of this safety requirements, nuclear power is the new material that serviceability is higher with the main development of electric wire.Yet existing cable can't satisfy the high-level requirement of nuclear power station, and radiation hardness and resistance to elevated temperatures are not high.
In a word, a kind of nuclear power does not appear in the newspapers as yet with screened cable.
Summary of the invention
In order to overcome the deficiency of existing phase-compensated cable, the purpose of this invention is to provide a kind of nuclear power screened cable.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of nuclear power screened cable comprises inner wire, and the described inner wire outside coats inner insulating layer;
The described inner insulating layer outside is surrounded with internal shield; The described internal shield outside coats external insulation layer; The described external insulation layer outside coats outer shielding layer;
Described internal conductor material is that stainless steel is led core;
Described inner insulating layer and external insulation layer material are insulation foaming AL2O3;
Described internal shield and outer shielding layer material are stainless steel tube.
The invention has the beneficial effects as follows:
1, the present invention has anti-high radiation, resistant to elevated temperatures characteristics.
2, mechanical strength height of the present invention, reliability height.
3, the present invention has characteristic wear-resisting, oil resistant.
