Cable proposes requiring without electromagnetic interference for " electromagnetic compatibility ", existing to fit as conventional power cable used in transmission electric power
The use environment for answering nuclear power station harshness can and control system production electrical to neighbouring distribution line when electric current passes through power cable
Raw interference, it is serious also to bring hidden danger to the normal operation of whole system, reduce the safety of nuclear power station.Moreover, core
There are hyperbaric environment in electricity cable use environment, conventional power cable uses easily deformable, existing core under hyperbaric environment
Power station power cable still has biggish deficiency in its mechanical strength.Currently, being badly in need of a kind of anti-interference and there is high knot
The power cable for nuclear power plant of structure intensity.
Summary of the invention
To solve the above-mentioned problems, the utility model discloses a kind of high-intensitive full-shield cable of nuclear power, one is provided
The high full-shield cable of kind good in anti-interference performance, structural strength.
The utility model is achieved through the following technical solutions:
A kind of high-intensitive full-shield cable of nuclear power, the cable includes several conductors, and insulation is extruded with outside the conductor
Layer, wrapped copper strips constitutes internal shield outside the insulating layer, and the conductor, insulating layer and internal shield constitute insulated wire cores, institute
State insulated wire cores and several strengthening cores it is twisted after constitute cable core, be extruded with inner sheath outside the cable core, it is wrapped outside the inner sheath
Two layers galvanized steel strip forms armor, is surrounded with fireprotection layer outside the armor, and the fireprotection layer is externally provided with oxygen barrier layer, it is described every
Oxygen layer is coated with external shielding layer, and oversheath is extruded with outside the external shielding layer.
The insulating layer is made of Ceramic silicon rubber.
The strengthening core uses carbon fiber strengthening core.
Inner sheath is halogen-free and low-smoke flame-retardant polyolefin sheathed using heat curing type.
The fireprotection layer is formed by fire-resistant isinglass belt is wrapped.
The oxygen barrier layer is magnesia oxygen barrier layer.
The external shielding layer uses aluminium alloy woven mesh structure.
The oversheath is the halogen-free and low-smoke flame-retardant polyolefin sheathed material of thermoplastics type.
Compared with prior art, the utility model has the beneficial effects that
Inside and outside two-layer screen layer is arranged in cable for the utility model good in anti-interference performance, extraneous during power Transmission
Electric and magnetic fields will not interfere power cable, the electromagnetic field that power cable generate during power transmission can also be shielded
It covers, electrically will not generate and interfere with control system to distribution line is closed on, internal shield and external shielding layer are respectively adopted around inclusion
Structure and woven mesh structure are conducive to the mechanical performance for enhancing cable while enhancing cable to extraneous anti-interference ability；Cable
Strengthening core is inside also had additional, the structural strength of cable is improved；Fireprotection layer and magnesia oxygen barrier layer are set gradually outside armor, when
When the outer layer of cable is ignited, magnesia oxygen barrier layer is not melted non-ignitable hard shell by thermosetting, plays the role of cooling and isolation, is kept away
Exempt from fire spreading and causes more huge economic loss, good flame retardation effect.
