Technical field
The invention belongs to electric power and technical field of cables, especially relate to a kind of modified node method cable and manufacture method.
Background technology
Electric wire is as key pillars of the national economy industry, and its ratio shared in national economy increases day by day. Comparing ripe industry as one, the joint Zhi Jiangben of electric wire is also more and more paid attention in industry, and the construction of cable is more in polarization, and one-level height is integrated complicated, multiple function is integrated, and saving is laid, running maintenance cost; Another level for simplifying the structure, when meeting industry standard, national standard, company standard, structure as far as possible simple, cost is as far as possible low, this kind of mode meets what the requirement of low carbocyclic ring. For this reason, the domestic structure for cable has carried out big quantifier elimination, and such as: to be CN103123824A, patent name be publication No.: a kind of cable with simple structure and manufacture method thereof, it is made up of many conductors, the restrictive coating that enveloped by conductor; It is characterized in that, between the two of arbitrary neighborhood piece conductor, there is restrictive coating material; On the cross section of cable, the edge of any conductor is all positioned within the border of restrictive coating; Described many conductors are along restrictive coating distribution, and do not contact between any two conductors; It is by offering cylindrical or the hole of fan cylinder shape in restrictive coating, conductor is inserted in hole and to form cable, this kind of mode reaches the object of simple structure really, but, irregular for the shape of restrictive coating between adjacent conductor, this kind of mode does not reasonably utilize space, and handiness mode can not meet requirement.
Power consumption cable operationally conductor can generate heat, and the increase along with load, thermal value can increase, the rising of temperature, the reduction of current-carrying capacity of cable can be caused, for this reason, expect in industry to make cable have good heat sinking function, the load of cable can be increased like this, and then the conductor usage quantity making the identical cable requiring current capacity reduces, the consumption of resource can be reduced, reduce the cost of cable, increase competitive power, more meet the requirement that low-carbon environment-friendly is energy-conservation.
Publication No. be CN103928135A patent discloses a kind of split conductor cable, include centre conductor and Duo Gen conductor, centre conductor is coated with insulation layer, many conductor loops are around the surrounding of centre conductor, and it is coated with cross section outside many conductors respectively in fan-shaped insulation layer, insulation layer outside centre conductor has gap respectively with between the insulation layer between the insulation layer outside many conductors and outside adjacent two conductors, and the insulation layer outside many conductors is coated with sheath;It is simple that it has structure, cross section makes protection more reliable in fan-shaped insulation layer, avoids and produces interference mutually between inner conductor, and the gap between insulation layer is not needing to improve heat dispersion under the prerequisite increasing any cooling mechanism, reduce cost, but radiating effect is still not ideal enough, what CN103871577A publication No. was patent discloses a kind of high strength easy heat radiation flat cable, comprise oversheath, at least two cores being contained in oversheath, when described cable be in stretch state time, the axis of all described cores is all in same plane, and the axis of all described cores keeps parallel, described core comprises conductor layer, the insulation layer of coated conductor layer, the metal armoring of coated insulation layer, the interior sheath of clad metal armouring, fixed by metal reinforcing between two adjacent groups metal armoring, fixed by stiffening web between sheath in two adjacent groups, the coated stiffening web of oversheath, stiffening web clad metal stiffening web, although it also can reach radiating effect, but, radiating effect still has the space of improvement.
