Background technology
Control cables is mainly used in the signal such as transfer control, measurement, is applicable to the occasions such as the control of the department such as industrial and mining enterprises, energy traffic, protection circuit.In prior art, the structural strength of control cables often can not meet user demand, usually can cause control cables to meet with and corrode or damage the useful life of having reduced cable in transportation or in installing and using process.Simultaneously traditional control cables structure is simple, the not environmental protection of use material, and while causing breaking out of fire, the flue gas that cable self burning produces happens occasionally to phenomenons such as human body damage.
Anti-electromagnetism refers to that equipment or system can normally be worked in residing electromagnetic environment and any other things in this environment is not formed the ability of the electromagnetic disturbance that can not bear.The screen of current control cables generally adopts proof copper-wire braided shielding, the wrapped shielding of copper strips, the wrapped shielding of steel band, the wrapped shielding of aluminium strip, proof copper-wire braided to add the wrapped shielding of copper strips etc., the shielding properties of this type shielding cable can only resist the general interference of electromagnetic field, and shield with aluminum pipe or copper pipe, although shielding properties is slightly improved, but flexibility is poor, can only uses in regulation and lay occasion.Because this kind control cable manufacturing technology is higher, shielding properties requirement is high, cable flexibility requires, and shielding construction design difficulty is large.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes the flexible super shielding of a kind of low smoke and zero halogen and control cable, there is good environmental protection characteristic, flexible characteristic and super shielding character, widen the mounting condition of control cables, reduced injury human body being caused because of the flue gas of cable burning generation itself.
Cable is controlled in the flexible super shielding of a kind of low smoke and zero halogen that the present invention proposes, comprise center conductor, center conductor by center part and successively aluminum plastic belt lapping layer and the polyolefin insulation layer outside coated center part form, center part is by several copper conductors, the stranded formation of gap-filler shall, the cross section of gap-filler shall is circular configuration, gap-filler shall is arranged between two copper conductors of arbitrary neighborhood, center conductor outer cladding control conductor layer, controlling two cavity filling bars of controlling between conductors that conductor layer is close to the parallel vertical control conductor of putting of center conductor by many and is arranged on arbitrary neighborhood forms, the cross section of cavity filling bar is annular, control conductor by pilot and be coated on successively the waterstop lapping layer outside pilot, tincopper fuse wire braided armor forms, control conductor layer and be coated successively polyester belt lapping layer outward, permeability alloys layer, zinc-plated soft copper band lapping layer and polyolefin jacket.
Preferably, pilot is single copper conductor.
Preferably, the copper conductor quantity in center part is 3-6 root.
Preferably, in control conductor layer, controlling number of conductors is 10-18 root.
Preferably, cavity filling bar is circumscribed with two control conductors of center conductor, arbitrary neighborhood respectively, with polyester belt lapping layer inscribe.
The present invention has good environmental protection characteristic, flexible characteristic and super shielding character, and polyolefin insulation layer, polyolefin jacket are Halogen organic substance, has reduced injury human body being caused because of the flue gas of cable burning generation itself; The aluminum plastic belt lapping layer, tincopper fuse wire braided armor, permeability alloys layer, the zinc-plated soft copper band lapping layer that set gradually from inside to outside, not only make cable have superpower screen, and flexible, expanded the mounting condition of control cables.
