Abstract
The utility model discloses an efficient shielded-type multi-core control cable. The efficient shielded-type multi-core control cable comprises a plurality of copper conductive wires, wherein each copper conductive wire is composed of a bare copper wire and a PVC (polyvinyl chloride) insulating layer coated on the bare copper wire, and a low-smoke zero-halogen flame-retardant outer sheath is coated on the plurality of copper conductive wires; and an insulating shielding layer, a metal shielding layer, a polyester belt, an isolating sleeve and a steel-tape armouring sheath are sequentially arranged between the outside of the plurality of copper conductive wires and the low-smoke zero-halogen flame-retardant outer sheath from inside to outside. The cable disclosed by the utility model is remarkably enhanced in signal shielding performance, flame-retardant performance and anti-tensile performance by adding the insulating shielding layer, the metal shielding layer, the polyester belt, the isolating sleeve and the steel-tape armouring sheath, can be used for transmitting a controlling signal in a high-intensity magnetic field environment and has the advantages of eliminating fire hidden danger and avoiding tensile damages.
Description
Technical field
The utility model relates to a kind of control cable, relates in particular to a kind of high-efficiency shielding type multi-core controlled cable that can be used for control signal transmission in the strong magnetic field circumstance.
Background technology
Along with the depth development of electron trade, also more and more higher to the cable performance requirement of control signal transmission, the particularly transmission of the control signal in the strong magnetic field circumstance, very high to the shielding properties requirement of cable, interference-free to guarantee control signals transmitted; Require to have higher fire resistance simultaneously, to avoid fire incident.Existing control cable kind is a lot, but its structure is roughly the same or similar, promptly form copper conductor by bare copper wire and the PVC insulating barrier that is coated on described bare copper wire outside, outside at many copper conductors coats the low-smoke non-halogen flame-retardant oversheath, though this structure also has good shielding and flame retardant effect, its performance also is not very desirable, in requiring high environment, still there is the problem that is subjected to magnetic interference and fire safety evaluating hidden danger, is difficult to guarantee control signal transmission accurately.
The utility model content
The purpose of this utility model provides a kind of high-efficiency shielding type multi-core controlled cable that can be used for control signal transmission in the strong magnetic field circumstance with regard to being in order to address the above problem.
The utility model is achieved through the following technical solutions above-mentioned purpose:
High-efficiency shielding type multi-core controlled cable described in the utility model comprises many copper conductors, and described copper conductor is made up of bare copper wire and the PVC insulating barrier that is coated on described bare copper wire outside, and the outside of described many copper conductors is coated with the low-smoke non-halogen flame-retardant oversheath; Be disposed with insulation screen, metal screen layer, polyester belt, separation sleeve and steel-tape armouring sheath from inside to outside between the outside of described many copper conductors and the described low-smoke non-halogen flame-retardant oversheath.
Particularly, described insulation screen is an asbestos layer, and described metal screen layer is a tincopper fuse wire braided armor, and described separation sleeve is the polyethylene separation sleeve.
Further, be filled with insulating material between the described many copper conductors.As preferably, described insulating material is a crosslinked polyethylene.
The beneficial effects of the utility model are:
The utility model is by increasing insulation screen, metal screen layer, polyester belt, separation sleeve and steel-tape armouring sheath, signal shielding performance, fire resistance and the stretch-proof performance of cable have significantly been strengthened, can be used for the control signal transmission in the strong magnetic field circumstance, and have the advantage of eliminating disaster hidden-trouble, avoiding fail in tension.
Description of drawings
Fig. 1 is the cross section view of high-efficiency shielding type multi-core controlled cable described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, high-efficiency shielding type multi-core controlled cable described in the utility model comprises many copper conductors, described copper conductor is formed by multiply bare copper wire boundling by bare copper wire 8(bare copper wire 8) and the PVC insulating barrier 7 that is coated on bare copper wire 7 outsides form, the outside of many copper conductors is coated with low-smoke non-halogen flame-retardant oversheath 1, is disposed with insulation screen 6, metal screen layer 5, polyester belt 4, separation sleeve 3 and steel-tape armouring sheath 2 between the outside of many copper conductors and the low-smoke non-halogen flame-retardant oversheath 1 from inside to outside; Be filled with insulating material between the many copper conductors---crosslinked polyethylene 9.The radical of copper conductor is decided by practical application request, is 7 in the utility model.
In the practical application, insulation screen 6, metal screen layer 5, separation sleeve 3 and low-smoke non-halogen flame-retardant thermosetting oversheath 1 all have multiple choices, in the utility model, insulation screen 6 is an asbestos layer, metal screen layer 5 is a tincopper fuse wire braided armor, separation sleeve 3 is the polyethylene separation sleeve, and low-smoke non-halogen flame-retardant thermosetting oversheath 1 is the fire-retardant oversheath of polyolefin.
As shown in Figure 1; copper conductor itself just has 7 pairs of bare copper wires of PVC insulating barrier 8 to carry out insulation shielding; fill isolation by crosslinked polyethylene 9 between the copper conductor; make the insulation property between the copper conductor better; and filled the space; the condition that has burning hardly, the outside of copper conductor realize high-efficiency shielding, insulation and anti-flaming function by insulation screen 6, metal screen layer 5, polyester belt 4 and separation sleeve 3 successively, reach the purpose of protection layer by layer.Steel-tape armouring sheath 2 plays stretch-proof, the anti-effect that damages, and outermost low-smoke non-halogen flame-retardant thermosetting oversheath 1 plays effect fire-retardant and protection.
