Description
Technical field
This utility model construction of cable technical field, is specifically related to a kind of used for oil platform
Intrinsically-safe instrument communication cable.
Background technology
The signal transmission that intrinsically-safe instrument communication cable is mainly used in essential safety loop.
At present in a lot of actual application, due to each side reason, intrinsically-safe instrument communication cable and
The production of conventional instrument communication cable is the same with application, protects outside the most simple handle
Set changes blueness into.This is in essential safety occasion, there is potential safety hazard, essence peace
The whole audience closes has strict requirements.When circuit switches or breaks down, its release
Energy can not light imflammable gas, thus explode, therefore intrinsically safe circuit requirement
Its electric product must be low electric capacity, low inductance, anti-interference, anlistatig.And it is general
Logical non-intrinsic safety cable does not substantially reach above-mentioned requirements at these aspect of performances, especially at stone
The occasion of oil these bad environments of platform, cannot meet related request especially.
Utility model content
For above technical problem, this utility model provides one can meet oil platform
Use the intrinsically-safe instrument communication cable of environmental requirement, there is good mechanical performance and resist
Interference performance.
This utility model be the technical scheme is that by its technical problem of solution
A kind of intrinsically-safe instrument communication cable used for oil platform, including four couple being placed in center
Cable core, is sequentially provided with compound total screen layer, sheath, braiding armouring outside four pairs of cable cores
Layer and outer jacket, the every pair of cable core is respectively by two stranded covered wires and be coated on
The sub-shield composition of two bar insulation line peripheries, covered wire includes the tin plating of the center that is placed in
Copper conductor and be coated on the insulating barrier outside tinned copper conductor, every pair of cable core is comprised
Covered wire use that different pitch is stranded to be formed, its twisting pitch no more than
65mm。
As preferred embodiment, described sub-shield includes the first of volume bag
Plastic-aluminum belt, axially disposed on the first plastic-aluminum belt have earial drainage line.
As preferred embodiment, described compound total screen layer wraps the most successively
Include the second wrapped plastic-aluminum belt and tincopper fuse wire braided armor.
As preferred embodiment, described sheath and outer jacket are hindered by low smoke and zero halogen
Combustion polyolefin composition, surface is provided with blue coating.
As preferred embodiment, described braiding armor is by zinc-coated wire or tin plating
Proof copper-wire braided forms.
As preferred embodiment, described insulating barrier is by crosslinked polyethylene insulation material
Make.
The beneficial effects of the utility model are: this utility model and non-intrinsically-safe instrument communication
Cable is compared, and to using, less twisting pitch is stranded to be formed line, and line strand pitch
Different, so can reduce intrinsically safe circuit by strong electromagnetic, and can subtract
Interfering and cross-talk between few line pair；Cable shield employing separated-shielding+always shield knot
Structure, greatly reduces the static interference of outer bound pair intrinsically safe circuit, reduces intrinsic safety cable
The energy storage of self, thus ensure that the energy storage in intrinsic safety loop is little under switching and failure condition
Minimum ignition energy in fuel gas；It is provided with outer jacket and sheath, cable cover(ing)
Under equal gross thickness, realize double sheath extrusion, and in the middle of interior outer jacket, set braiding armouring
Layer, adds the mechanical performance of cable and jamproof performance.
Accompanying drawing explanation
It is further detailed with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is cross-sectional view of the present utility model.
Accompanying drawing illustrates: 1-sheath, 2-weaves armor, 3-outer jacket, and 4-is tin plating
Copper conductor, 5-insulating barrier, 6-the first plastic-aluminum belt, 7-earial drainage line, 8-the second aluminum plastic belt
Layer, 9-tincopper fuse wire braided armor.
Detailed description of the invention
With reference to Fig. 1, one of the present utility model intrinsically-safe instrument used for oil platform communication electricity
Cable is mainly by four pairs of cable cores, compound total screen layer, sheath 1, braiding armor 2
And outer jacket 3 forms.Sheath 1 and outer jacket 3 are by low-smoke non-halogen flame-retardant polyene
Hydrocarbon forms, and surface is provided with blue coating.Braiding armor 2 is by zinc-coated wire or tin plating
Proof copper-wire braided forms.The setting of sheath 1 and outer jacket 3 makes cable cover(ing) same
Extrude etc. realizing double sheath under gross thickness, and in the middle of interior outer jacket, set braiding armor 2,
Add the mechanical performance of cable and jamproof performance.
The every pair of cable core is respectively by two stranded covered wires and be coated on two bar insulations
The sub-shield composition of line periphery.Covered wire includes the tinned copper conductor 4 at the center that is placed in
And it being coated on the insulating barrier 5 outside tinned copper conductor 4, the every pair of cable core is comprised
Covered wire uses that different pitch is stranded to be formed, and its twisting pitch is no more than 65mm.
Fitted tightly by insulating barrier 5 between cable core.Usually, insulating barrier 5 uses crosslinking
Polyethylene insulation material is made.In order to reach good shield effectiveness, sub-shield bag
Include the first plastic-aluminum belt 6 of volume bag, the first plastic-aluminum belt 6 interts vertically
There is earial drainage line 7.To using, less twisting pitch is stranded to be formed line, and line strand joint
Away from different, so can reduce intrinsically safe circuit and be done by the electromagnetism of forceful electric power circuit
Disturb, and interfering and cross-talk between line pair can be reduced.
Compound total screen layer includes the second aluminum plastic belt of volume bag the most successively
Layer 8 and tincopper fuse wire braided armor 9.Second plastic-aluminum belt 8 tight is right in four
Outside cable core so that cable core structure fastens.Dividing outside compound total screen layer and every pair of cable core
Screen layer coordinates, and can greatly reduce the static interference of outer bound pair intrinsically safe circuit, reduces
The energy storage of intrinsic safety cable self, thus ensure that intrinsic safety returns under switching and failure condition
The energy storage on road is less than the minimum ignition energy of fuel gas.
The foregoing is only preferred embodiment of the present utility model, be not used to limit
This utility model processed, for a person skilled in the art, this utility model is permissible
There are various modifications and variations.All within spirit of the present utility model and principle, made
Any modification, equivalent substitution and improvement etc., should be included in guarantor of the present utility model
Within the scope of protecting.
