Description
Technical field
This utility model relates to field of cables, is specifically related to a kind of intrinsic safety type electrical equipment and controls cable.
Background technology
At present, in Large Scale Construction Engineering electrical apparatus controlling system, the cable laying of transmitting telecommunication number is complicated, and the phenomenon that easily causes confusion, and adds construction period, and maintenance work in the future is the most comparatively laborious；It it is the main contributor causing explosion hazard gases blast at spark and heat effect, and consider from system wiring engineering viewpoint, owing to cable is that many distribution capacity, inductance equal distribution element are formed, it is made correspondingly to become energy-storage travelling wave tube, therefore energy is inevitably stored in electric signal transmitting procedure, open circuit or short circuit occur once when circuit, these energy storage will discharge with the form of electric spark or heat effect, is easily formed bigger potential safety hazard in some specific inflammable and explosive environment and region.
Utility model content
In order to overcome the deficiencies in the prior art, it is provided that a kind of low electric capacity, low inductance, acid and alkali-resistance, oxygen-proof property is good, shielding is good intrinsic safety type electrical equipment control cable.
For achieving the above object, this utility model provides a kind of intrinsic safety type electrical equipment with controlling cable, including cable core, outside cable core, weave high density copper wire sub-shield that thickness is 2mm successively, Jacket thickness is the silver-plated annealing copper strips armor of 3mm, cladding thickness is 4mm copper is moulded the total screen layer of composite membrane band and extrudes the plastic-aluminum armouring pe sheath layer that thickness is 5mm；Described cable core is formed by two tinned copper conductors being made up of 7 tinned copper wires and two tin plating nickel conductor strand being made up of 12 tin plating nickel wires；Layer of polyester fiber is filled in the gap of stranded rear cable core.
Improving further, described copper is moulded composite membrane band total screen layer inner conducting layer and is added the B class conductor copper wire ground wire that one group of folder is symmetrical.
Improving further, the cross-sectional diameter length of described tinned copper conductor is 7:12 with the ratio of the cross-sectional diameter length of tin plating nickel conductor.
Compared with prior art, the beneficial effects of the utility model are:
1, this utility model has environmental protection, low electric capacity, low inductance, shielding properties is excellent, the multiple good characteristics such as anti-electromagnetism, Radio frequency interference performance and anti-power plant coupling performance are strong, use in conjunction with support circuit and equipment, can effectively eliminate electric spark and heat effect release, explosion-proof performance is excellent, and low-smoke halogen-free polyolefin sheath is prone to installation and debugging and the isolation of cable in explosion-proof environment.
2, to have environment protecting good for this utility model, has lightweight, and acid and alkali-resistance, shield effectiveness is good, the advantage that oxygen-proof property is strong.
3, this utility model cable has low electric capacity and the feature of low inductance, owing to have employed sub-shield and the double-decker of total screen layer, make it have fabulous shielding properties, anti-external electromagnetic field disturbs, the ability of anti-Radio frequency interference and anti-field coupling is the strongest, thus the rated voltage being also used as in the industrial department explosive environments such as chemistry and oil is 450/750 and in the intrinsicallysafecircuit such as following distributing system and automatic detection and control system as the transmission line of small-signal, can be widely applied to oil, chemical industry, electric power, gas engineering, there is the occasion of explosion danger in mines etc. and other anti-explosion safety requires higher occasion.
4, the thickness of outer every layer of this cable is all incremented by 1mm so that the rounding property of cable is more preferable, thus improves the properties of cable, improves quality and the service life of cable.
5, in total screen layer, it is additionally provided with one group of ground wire, prevents cable leakage from causing spark, bring blast and harm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with this utility model, it should be understood that these embodiments are merely to illustrate this utility model rather than limit scope of the present utility model, after having read this utility model, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present utility model.
As shown in Figure 1, this utility model provides a kind of intrinsic safety type electrical equipment with controlling cable, including cable core, including cable core, outside cable core, weave high density copper wire sub-shield 4 that thickness is 2mm successively, Jacket thickness is the silver-plated annealing copper strips armor 5 of 3mm, cladding thickness is 4mm copper is moulded the total screen layer of composite membrane band 6 and extrudes the plastic-aluminum armouring pe sheath layer 7 that thickness is 5mm；The thickness of every layer is all incremented by 1mm so that the rounding property of cable is more preferable, thus improves the properties of cable, improves quality and the service life of cable；Described cable core is formed by two tinned copper conductors being made up of 7 tinned copper wires 91 and two tin plating nickel conductors 2 being made up of 12 tin plating nickel wires 10 are stranded；Fill layer of polyester fiber 3 in the gap of stranded rear cable core, polyester fiber has extension under certain pulling force, and coefficient of friction is big, has certain heat-shrinkable, heatproof index can reach 185.6 degrees Celsius, improves the performance of cable.
Described copper is moulded composite membrane band total screen layer 6 inner conducting layer and is added the B class conductor copper wire ground wire 8 that one group of folder is symmetrical.
The cross-sectional diameter length of described tinned copper conductor is 7:12 with the ratio of the cross-sectional diameter length of tin plating nickel conductor, this cable not only used 2 kinds of different conductors, also its size is arranged so that the most more can merge so that the overall performance of cable reaches best.
This utility model cable has low electric capacity and the feature of low inductance, owing to have employed sub-shield and the double-decker of total screen layer, make it have fabulous shielding properties, anti-external electromagnetic field disturbs, the ability of anti-Radio frequency interference and anti-field coupling is the strongest, thus the rated voltage being also used as in the industrial department explosive environments such as chemistry and oil is 450/750 and in the intrinsicallysafecircuit such as following distributing system and automatic detection and control system as the transmission line of small-signal, can be widely applied to oil, chemical industry, electric power, gas engineering, there is the occasion of explosion danger in mines etc. and other anti-explosion safety requires higher occasion.
The above is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of without departing from this utility model principle; can also make some modification and improvement, these also should be regarded as belonging to protection domain of the present utility model.
