Abstract
The present invention discloses a kind of inert gas shielding composite cable; the gas-guide tube of inert gas including innermost layer; inert gas is filled in the gas-guide tube, the uniform arrangement in periphery of the gas-guide tube is equipped with a circle and squeezes item, and the outside for squeezing item is wrapped up by the extruded layer of setting；Uniformly be placed with eight conductors by insulating layer package covering outside the extruded layer, eight insulating layers uniformly arranged after by the wrapped stranding of Mica tape layer.The extruding item made in the evenly distributed rubber material of one circle of external setting of gas-guide tube in the present invention; external conductor is via setting arranged in a ring after insulating layer insulation package on squeezing item; gas-guide tube can be effectively protected when external pressure is larger not destroyed by crunch; absorbing external partial pressure increases the service life of gas-guide tube；In addition fire resistance is increased by Mica tape outside insulating layer, and shielded layer and waterproof layer increase shield effectiveness and water resistance is set.
Description
Technical field
A kind of pair twist cable of the present invention, and in particular to inert gas shielding composite cable.
Background technology
Inert gas composite cable refers to wrapping up the gas-guide tube of an inert gas at the middle part of cable, is filled in gas-guide tube
There is inert gas, can make to work in the environment of conductor high temperature and pressure again under the protection of inert gas, existing inert gas
Filling pipe majority use cross-linking radiation gas-guide tube, certain pressure, bending and drawing force can be born, but actually used
When sometimes gas-guide tube receive external pressure it is larger when still can lead to conductor tube flexural deformation, reduce and benefit from the service life, finally
Cause conductor tube damaged, inert gas effusion.
Invention content
The purpose of the present invention is in view of the deficienciess of the prior art, provide a kind of inert gas shielding composite cable,
Technical solution is as follows：
A kind of inert gas shielding composite cable, includes the gas-guide tube of the inert gas of innermost layer, filling in the gas-guide tube
There is inert gas, uniformly arrangement is equipped with circle extruding item for the periphery of the gas-guide tube, and the outside for squeezing item passes through setting
Extruded layer package；Eight conductors by insulating layer package covering, eight insulating layer quilts are uniformly placed with outside the extruded layer
Uniformly pass through the wrapped stranding of Mica tape layer after arrangement；The wrapping layer is coated with shielded layer, outside the shielded layer
It is coated with waterproof layer, the waterproof layer is coated with sheath.
Preferably, the pipe outer wall of the gas-guide tube is additionally provided with several arc grooves, the extruding item can be uniform
Arrangement is mounted in arc groove.
Preferably, the gas-guide tube is set as cross-linking radiation gas-guide tube, wall thickness 5mm.
Preferably, the extruding item is set as rubber extruded item, outer diameter is set as 2mm；The extruded layer is same
It is set as the extruded layer of rubber material making, the thickness of the extruded layer is 1mm.
Preferably, being additionally provided with tearing rope structure between the insulating layer of eight conductors.
Advantageous effect：The invention has the advantages that：One circle of external setting in the present invention in gas-guide tube is uniformly arranged
The extruding item that the rubber material of row makes, external conductor are squeezing item via setting arranged in a ring after insulating layer insulation package
On, squeezing item has certain crimp ability, and it is powerful to be effectively protected gas-guide tube when external pressure is larger
Pressure is destroyed, and absorbing external partial pressure increases the service life of gas-guide tube；In addition outside insulating layer by mica tape around
Packet increases fire resistance, and shielded layer and waterproof layer increase shield effectiveness and water resistance is arranged.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, and the present embodiment is with technical solution of the present invention
Premised under implemented, it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in Figure 1, a kind of inert gas shielding composite cable, includes the gas-guide tube 1 of the inert gas of innermost layer, this is led
Inert gas is filled in tracheae 1, the uniform arrangement in periphery of the gas-guide tube 1 is equipped with a circle and squeezes item 2, and squeezes item 2
Outside wrapped up by the extruded layer 3 of setting；Eight are uniformly placed with outside the extruded layer 3 by the package covering of insulating layer 4
Conductor 5, eight insulating layers 4 by uniformly arranged after by 6 wrapped stranding of Mica tape layer；The wrapping layer 6 is coated with
Shielded layer 7, the shielded layer 7 are coated with waterproof layer 8, and the waterproof layer 8 is coated with sheath 9.
The pipe outer wall of the gas-guide tube 1 is additionally provided with several arc grooves, and the extruding item 2 can uniformly arrange installation
In arc groove；The gas-guide tube 1 is set as cross-linking radiation gas-guide tube, wall thickness 5mm；The extruding item 2 is set as
Rubber extruded item, outer diameter are set as 2mm；The extruded layer 3 is likewise provided as the extruded layer 3 of rubber material making, the extruding
The thickness of layer 3 is 1mm；Tearing rope structure 10 is additionally provided between the insulating layer 4 of eight conductors.
The extruding item made in the evenly distributed rubber material of one circle of external setting of gas-guide tube in the present invention, external leads
For body via setting arranged in a ring after insulating layer insulation package on squeezing item, squeezing item has certain crimp ability,
It can be effectively protected gas-guide tube when external pressure is larger not destroyed by crunch, absorbing external partial pressure, increase
The service life of gas-guide tube；In addition fire resistance is increased, and shielded layer and waterproof is arranged by Mica tape outside insulating layer
Layer increases shield effectiveness and water resistance.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
