Description
Technical field
The utility model relates to electric wire field, refers in particular to a kind of naval vessel intermediate frequency rubber sleeve flexible cable.
Background technology
Naval vessel intermediate frequency rubber sleeve flexible cable is from intermediate frequency quiescence power supply to intermediate frequency distribution panelboard to Intermediate frequency power supply system terminal control mechanism cable, and conductor is common zinc-plated five class conductors.Conventional intermediate frequency rubber sleeve flexible cable naval vessel, naval vessel is generally 4 cored structures, three phase cores and a neutral core.
Prior art Problems existing and shortcoming:
(1) alternate conductor resistance deviation is larger;
(2) dielectric loss tangent of common insulating material is large, causes that cable dielectric loss is excessive, pressure drop is excessive and phase insulation resistance unbalance, lower electrical insulation capability;
(3) adopt 0+4 asymmetric formula mode stranding, alternate due to approach effect and kelvin effect obvious, Electric Field Distribution is uneven, and impedance increases, and harmonic wave serious interference, has a strong impact on the life-span of cable.
Utility model content
Technical problem to be solved in the utility model is to overcome prior art defect, provides the naval vessel intermediate frequency rubber sleeve flexible cable that a kind of kelvin effect is good, ampacity is high, anti-interference, conductance is high.
In order to solve the problems of the technologies described above, the utility model provides a kind of naval vessel intermediate frequency rubber sleeve flexible cable, comprises cable core, extrudes oversheath outside cable core; Described cable center is provided with a neutral line insulated wire cores, then is placed in six roots of sensation phase line insulated wire cores in the surrounding of neutral line insulated wire cores, adopts 1+6 structure to twist together formation cable core.
Further improvement, described neutral line insulated wire cores is made up of neutral conductor and the neutral line insulating barrier be extruded in outside neutral conductor.
Further improvement, described phase line insulated wire cores is made up of phase conductor and the phase line insulating layer be extruded in outside phase conductor.
Beneficial effect of the present invention is:
A. add the surface area of conductor thread core, utilize kelvin effect effectively can reduce impedance, thus reduce loss when running, effectively can improve the ampacity of cable;
B. adopt 1+6 holohedral symmetry lay configuration, can ensure that the humorous wave interference of equipment to cable is minimum, Electric Field Distribution is even, improves cable reliability of operation;
C. every two line parallels mutually run, can when a line fault, and another line keeps emergency operating (but electric current reduction) in short-term, thus can improve the reliability of system cloud gray model.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Figure 1, a kind of naval vessel described in the utility model intermediate frequency rubber sleeve flexible cable, comprises cable core, extrudes oversheath 5 outside cable core; Described cable center is provided with a neutral line insulated wire cores, then is placed in six roots of sensation phase line insulated wire cores in the surrounding of neutral line insulated wire cores, adopts 1+6 structure to twist together formation cable core.Wherein, described neutral line insulated wire cores is made up of neutral conductor 3 and the neutral line insulating barrier 4 be extruded in outside neutral conductor 3; Described phase line insulated wire cores is made up of phase conductor 1 and the phase line insulating layer 2 be extruded in outside phase conductor 1.
Utility model works principle or the course of work:
For meeting the particular/special requirement that naval vessel intermediate frequency rubber sleeve flexible cable uses on naval vessel, mainly realize from following aspect:
1, copper wire adopts Ni Huofu multiple drawing machine, copper content >=99.99%, and conductor monofilament deviation ensures that monofilament elongates rate controls >=15%, monofilament electricalresistivityρ 20≤0.017241 Ω mm2/m at ± 0.001mm; Zinc-plated employing electroplating technology, do not allow to adopt hot plating technology, electroplating technology can ensure that monofilament electroplating surfaces with tin layer firmly sticks to the surface of copper cash, and ensure that the continuity of tin coating, thickness is even; Stranded layered is stranded, and every layer of pitch multiple proportions controls, within 12 times, to ensure stranded compactness, and conductor distortion is little, meanwhile, guarantees that every root monofilament or synnema strand can not have welding or joint, ensures every phase conductor resistance deviation≤0.5%.
2, novel insulating material is adopted, the Ethylene Propylene Terpolymer insulating rubber material of dielectric loss tangent tan δ < 0.003, moisture balance formula steam vulcanization (cure) technology is adopted to extrude, after rubber is extruded, directly enter curing tube carry out sulfuration, cool insulated wire cores while steam vulcanization (cure), curing medium is saturated steam.Its energy is from the vaporization potential of running water, and thermal capacity is large, and heat transfer efficiency is high, and pressure and temperature has air pressure adjustment, and with this understanding, rubber becomes net vertical body structure by linear structure, completes sulfuration.Effectively can improve the mechanical performance of insulation and the resistance to thermal level of product, namely under corresponding equivalent conductors cross section, improve the ampacity of cable.Insulation resistance Deviation Control ,≤1%, keeps the balance of phase insulation resistance.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection range of the present utility model.
