Abstract
The utility model relates to a flat steel wire armored protective instrument cable, and belongs to the technical field of instrument cables. The technical solution is that the flat steel wire armored protective instrument cable comprises copper conductors (11), and a copper conductor core is externally provided with a crosslinked polyethylene insulating layer (12), a polyester wrapping tape (13), a tined copper wire grounding wire (14), an aluminum-plastic composite film shielding layer (15), a PVC lining layer (16), a flat steel wire armored layer (17) and a PVC external protecting layer (18) in sequence. The flat steel wire armored protective instrument cable has the beneficial effects that flat steel wires are enabled to be uniformly distributed along a wire dividing guide wheel, and the internal stress is eliminated at the same time, thereby enabling the flat steel wire armored cable to be flat, straight and round; the flat steel wire armoring overcomes the defect that round steel wires are poor in side pressure resisting capacity, and meanwhile, has excellent tension protective capability and good protective performance; and protective instrument cable is armored by adopting the flat steel wire, thereby being thin in steel wire thickness, light in weight, and saving the cable cost.
Description
Technical field
The utility model relates to a kind of flat wire armoring protection instrument cable, belongs to the instrument cable technical field.
Background technology
At present, instrument cable is mainly used in the signal transmission of electronic computer system, monitoring loop, automation control system etc., and is higher to the cable machinery barrier propterty.And the metal armouring that is used for the instrument cable tensile elements is generally thin round steel wire and thick round steel wire, and the tension effect of these two kinds of round steel wires is pretty good, but the lateral pressure resistant protective capacities is relatively poor; Instrument cable in use not only often is subjected to tension external force, and when often being subjected to lateral pressure resistant external force, the inferior position of round steel wire armouring has just displayed.On the one hand, because round steel wire and cable inner covering contact-making surface are less, and the round steel wire diameter is less, when cable was subjected to side pressure, the steel wire that is under pressure can increase the pressure that cable body produces, and can produce impression to inner covering, can be damaged to insulated wire cores when serious, influence the signal transmission.On the other hand, round steel wire can produce with inner covering when being subjected to side pressure and slide out loose distortion now, makes to produce big gap between the round steel wire, and round steel wire just can not well be protected cable core like this, and round steel wire armouring cost is higher.
The utility model content
The purpose of this utility model provides a kind of flat wire armoring protection instrument cable, and cost is lower, and tension and lateral pressure resistant ability are good, solve the problems referred to above that exist in the background technology.
Technical solutions of the utility model are: a kind of flat wire armoring protection instrument cable, comprise copper conductor, the copper conductor core is provided with crosslinked polyetylene insulated layer, polyester film band, tinned copper wire earth connection, aluminum-plastic composite membrane screen, PVC inner covering, flat wire armoring layer and PVC outer jacket outward successively; Described crosslinked polyetylene insulated layer, be that copper conductor extrudes the XLPE insulation outward, constitute insulated wire cores, it is right that insulated wire cores is twisted in twos, constitute the unit group, several unit fabrics become into cable core, become the wrapped polyester film band in cable core outside, the multiply of wrapped aluminum-plastic composite membrane screen, and adding simultaneously tinned copper wire earth connection; The aluminum-plastic composite membrane screen extrudes the PVC inner covering outward, the outer wrapped flat wire armoring layer of PVC inner covering, and flat wire armoring layer extrudes the PVC outer jacket outward.
Described flat wire armoring layer is the many wrapped sheathed structures of flat steel wire, has good tension, lateral pressure resistant barrier propterty.
Described flat steel wire is zinc-plated flat steel wire, and thickness is 0.4mm-0.8mmmm, and width is 4mm-6mm.Because flat steel wire itself has certain elasticity, internal stress is bigger, is easy to overturn at cable in the armouring process, makes flat wire armoring out-of-flatness, and skewness.
Flat steel wire evenly distributes along the PVC liner surface behind the armouring, cable outward appearance rounding, flat steel wire coverage rate 〉=95%.Because flat steel wire and cable PVC inner covering contact-making surface are bigger, flat steel wire is less to the pressure of cable generation when being under pressure, and and the PVC inner covering between be not prone to slip, can well play the lateral pressure resistant protective action to cable.
Good effect of the present utility model is: the utility model makes flat steel wire evenly distribute along a minute wire carrier, has eliminated internal stress simultaneously, thereby makes straight, the rounding of flat steel wire armored cable; Flat wire armoring has overcome the bad shortcoming of round steel wire lateral pressure resistant ability, has fine tension protective capacities simultaneously, and barrier propterty is good; Adopt flat wire armoring, the steel wire thin thickness, in light weight, save cable cost.

Fig. 1 is the flat wire armoring protection of the utility model embodiment instrument cable sectional schematic diagram;
Among the figure: copper conductor 11, crosslinked polyetylene insulated layer 12, polyester film band 13, tinned copper wire earth connection 14, aluminum-plastic composite membrane screen 15, PVC inner covering 16, flat wire armoring layer 17, PVC outer jacket 18.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
A kind of flat wire armoring protection instrument cable, comprise copper conductor 11, the copper conductor core is provided with crosslinked polyetylene insulated layer 12, polyester film band 13, tinned copper wire earth connection 14, aluminum-plastic composite membrane screen 15, PVC inner covering 16, flat wire armoring layer 17 and PVC outer jacket 18 outward successively; Described crosslinked polyetylene insulated layer, be that copper conductor extrudes the XLPE insulation outward, constitute insulated wire cores, it is right that insulated wire cores is twisted in twos, constitute the unit group, several unit fabrics become into cable core, become the wrapped polyester film band in cable core outside, the multiply of wrapped aluminum-plastic composite membrane screen, and adding simultaneously tinned copper wire earth connection; The aluminum-plastic composite membrane screen extrudes the PVC inner covering outward, the outer wrapped flat wire armoring layer of PVC inner covering, and flat wire armoring layer extrudes the PVC outer jacket outward.
Described flat wire armoring layer is the many wrapped sheathed structures of flat steel wire, has good tension, lateral pressure resistant barrier propterty.
Described flat steel wire is zinc-plated flat steel wire, and thickness is 0.4mm-0.8mmmm, and width is 4mm-6mm.Because flat steel wire itself has certain elasticity, internal stress is bigger, is easy to overturn at cable in the armouring process, makes flat wire armoring out-of-flatness, and skewness.
Flat steel wire evenly distributes along the PVC liner surface behind the armouring, cable outward appearance rounding, flat steel wire coverage rate 〉=95%.Because flat steel wire and cable PVC inner covering contact-making surface are bigger, flat steel wire is less to the pressure of cable generation when being under pressure, and and the PVC inner covering between be not prone to slip, can well play the lateral pressure resistant protective action to cable.
