Background technology:
Power cord cable anti-interference problem is more and more important, and especially, in the operational environment of electro-mechanical system, the cable using in many modern facilities, requires antijamming capability stronger, to reach the object that suppresses interference.
Interference problem is the major issue that must consider in mechatronics system design and use procedure.In the operational environment of electro-mechanical system, there is a large amount of electromagnetic signals, as electromagnetic radiation of the start and stop of the fluctuation of electrical network, heavy current installation, high-tension apparatus and switch etc., when they produce electromagnetic induction and impact of interference in system, tend is upset the normal operation of system, the lighter causes the unstable of system, has reduced the precision of system; Severe one can cause that control system crashes or misoperation, causes device damage or loss of life or personal injury.
In addition, for the insulation property of power cable, resistance to torsion Qu Neng etc., be all the problem that must consider, insulation property do not reach the instructions for use of electro-mechanical system actual environment, there will be equally electric power transfer fault; Torsional resistance is poor, there will be disconnected core phenomenon in mounting and installation process, and electric power transfer is thoroughly interrupted.
Utility model content:
The purpose of this utility model is to provide the bent compound insulated power cable of a kind of flexible anti-torque, solves existing cable in the operational environment of electro-mechanical system, and anti-electromagnetic interference performance is poor, is subject to the interference of electromagnetic field; Insulation property affect electric power transfer; Torsional resistance affects the technical problems such as cable installation.
Technical scheme of the present utility model is as follows:
The bent compound insulated power cable of flexible anti-torque, comprise some alloy conductors, it is characterized in that: some described alloy conductors are enclosed with fire-resistant isinglass belt insulating barrier outward respectively successively, separator, organosilane crosslinked polyethylene insulation layer forms insulated wire cores, described separator adopts foamed plastic extrusion moulding to form, the mutual stranded bunchy of described insulated wire cores forms cable core, cable core is enclosed with the belting layer of the overlapping wrapped formation of polyester belt outward successively, lapped shielding layer, be wound around braid, being wound around braid adopts copper strips spiral winding to form, be wound around spacing and be not more than 3.2mm, be wound around braid and be coated with flame-proof polyvinyl chloride restrictive coating.
The bent compound insulated power cable of described flexible anti-torque, is characterized in that: the outermost layer twisting pitch of the cable of described the 1st, 2 kinds of conductor structures of some alloy conductors employings is not more than 22 times of the outside diameter of cable; Adopt the outermost layer twisting pitch of the cable of the 5th kind of conductor structure to be not more than 18 times of the outside diameter of cable.
The bent compound insulated power cable of described flexible anti-torque, is characterized in that: described lapped shielding layer adopts aluminium-plastic tape shielding, and wrapped Duplication is not less than 18%; Symmetrically vertical under lapped shielding layer put two nominal crosss and be not less than 0.4mm
2copper strips as drainage band.
The utility model has the advantages that:
The utility model structural design is novel, adopts alloy conductor to improve flexible, coordinates and is wound around the torsional resistance that braid can improve cable greatly; Lapped shielding layer, winding braid are used in the operational environment of electro-mechanical system, and anti-electromagnetic interference performance improves, and is not subject to the interference of electromagnetic field; Double hyer insulation guarantees that cable electric power transfer is stable.
