Abstract
The utility model discloses a kind of intrinsic safe explosion-proof and control cable, include conductor wire core, conductor wire core include conductor and be wrapped in vapour cooking outside conductor extrude crosslinked polyetylene insulated layer, will multiple conductor wire core bundles twist after be surrounded by Tarpauling lapping layer, aluminium-plastic tape lapped shielding layer, tinned copper wire woven shield and extruding polrvinyl chloride oversheath the most successively.This utility model have employed double layer screen, feature is low electric capacity, is difficult to storing charge, there is good shielding properties, the ability with antistatic property and the interference of anti-external electromagnetic field, anti-Radio frequency interference and anti-field coupling is the strongest, and there is anti-flammability, even if can be short-circuited or electric spark by circuit, also it is not enough to light the flammable explosive gas of surrounding.
Description
Technical field
This utility model relates to field of cable technology, particularly relates to a kind of intrinsic safe explosion-proof and controls cable.
Background technology
Cable has electric conductivity, is widely used in each different field, relates to people's lives, commercial production every field,
So the consumption of cable is the hugest, being also the most important, the requirement to quality also can be more and more higher, but every field with
And each area requires it is different to the quality purposes of cable, such as the Ministry of Industry for explosive atmospheres such as chemistry and oil
The rated voltage of door is 450/750 and in the intrinsicallysafecircuit such as following distributing system and automatic detection and control system, transmission is used
Line, it is desirable in addition to having the feature of low electric capacity, low inductance, also has fabulous shielding properties, therefore anti-external electromagnetic field disturbs, resists
The ability of Radio frequency interference and anti-field coupling is the strongest, and this type of cable existing is not met by use demand, needs to change
Enter.
Utility model content
This utility model purpose is contemplated to make up the defect of prior art, it is provided that a kind of intrinsic safe explosion-proof controls cable.
This utility model is achieved through the following technical solutions:
A kind of intrinsic safe explosion-proof controls cable, includes conductor wire core, and conductor wire core includes conductor and is wrapped in outside conductor
The vapour cooking of side extrude crosslinked polyetylene insulated layer, after being twisted by multiple conductor wire core bundles, to be surrounded by Tarpauling the most successively wrapped
Layer, aluminium-plastic tape lapped shielding layer, tinned copper wire woven shield and extruding polrvinyl chloride oversheath.
Described conductor is formed by many oxygen-free copper tow strands.
This new product, in addition to having the feature of low electric capacity, low inductance, also has a fabulous shielding properties, therefore anti-external electromagnetic
The ability of field interference, anti-Radio frequency interference and anti-field coupling is the strongest, thus can be as explosive atmospheres such as chemistry and oil
The rated voltage of industrial department be 450/750 and the intrinsicallysafecircuit such as following distributing system and automatic detection and control system
Middle transmission line.
Conductor wire core is made up of conductor and insulation；Conductor uses the copper free wire meeting GB/T 3956 standard, it is ensured that have excellent
Good resistivity.
Insulation employing extrudes crosslinked polyethylene through vapour cooking so that strand is network structure, thus resistance to environment should
Power cracking, low temperature impact strength, elongation at break, ageing-resistant, toughness, rigidity, high temperature Tensile strength, chemical solvent resistance
The service life of energy, water vapor rejection rate and product all increases.
Shielding uses aluminium-plastic tape to add tinned copper wire double layer screen to strengthen the work such as anti-Radio frequency interference, anti-external magnetic field interference
With.
Sheath uses polrvinyl chloride squash type mode, makes the construction of cable tightr.
The utility model has the advantages that: this utility model have employed double layer screen, feature is low electric capacity, is difficult to storage electricity
Lotus, has good shielding properties, has antistatic property and the interference of anti-external electromagnetic field, anti-Radio frequency interference and anti-field coupling
Ability the strongest, and there is anti-flammability, even if can be short-circuited or electric spark by circuit, be also not enough to light surrounding inflammable easily
Explosive gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of intrinsic safe explosion-proof controls cable, including conductor wire core, conductor wire core includes conductor 1 and bag
Be rolled in the vapour cooking outside conductor 1 extrudes crosslinked polyetylene insulated layer 2, is surrounded by the most successively after being twisted by multiple conductor wire core bundles
Tarpauling lapping layer 3, aluminium-plastic tape lapped shielding layer 4, tinned copper wire woven shield 5 and extruding polrvinyl chloride oversheath
6。
Described conductor 1 is formed by many oxygen-free copper tow strands.
Claims (2)
1. an intrinsic safe explosion-proof controls cable, it is characterised in that: including conductor wire core, conductor wire core includes conductor and parcel
Vapour cooking outside conductor extrude crosslinked polyetylene insulated layer, by multiple conductor wire core bundles twist after be surrounded by the most successively waterproof
Canvas lapping layer, aluminium-plastic tape lapped shielding layer, tinned copper wire woven shield and extruding polrvinyl chloride oversheath.
A kind of intrinsic safe explosion-proof the most according to claim 1 controls cable, it is characterised in that: described conductor is by many nothings
Oxygen copper wire bundle strand.
