Abstract

The invention provides an interlocking type armored optical fiber composite low-voltage cable of a creep-resistant aluminum alloy conductor. The interlocking type armored optical fiber composite low-voltage cable comprises a conductor, an optical unit and an armor, wherein the conductor is the creep-resistant aluminum alloy conductor; and the armor is aluminum alloy strip interlocking type armor. The interlocking type armored optical fiber composite low-voltage cable has the advantages that: the conductivity can reach over 61 percent of International annealed copper standard (IACS); the conductor has excellent mechanical property; the rebound performance of the conductor is 40 percent lower than that of a copper cable; the flexible performance is 25 percent higher than that of the copper cable; and the weight of the conductor is half of that of the copper cable; when an alloy cable is used, the installation cost is directly reduced for a construction organization; an S-type interlocking type armor structure is used; the armored cable has high softness, and high strength; the minimum bending radius of the armored cable is 7D; the cable is reliable in connection, light in weight, small in bending radius, convenient for installation, good in radiation, bridge saving and resource saving; compared with common copper core low-voltage cable, the cable has obvious cost advantage, and saves large amount of copper; and the economical efficiency of the creep-resistant aluminum alloy interlocking type armored optical fiber composite low-voltage cable (OPLC) is adaptable to tendency of establishing the resource-saving society in China.

Description

technical field [0001] The invention relates to the technical field of making OPLC optical fiber composite low-voltage cables, in particular to a creep-resistant aluminum alloy conductor interlocking armored optical fiber composite low-voltage cable. Background technique [0002] Generally, there are two types of structures for designing and manufacturing OPLC optical fiber composite low-voltage cables: non-armored and armored. The conductor is mostly made of electrical copper, the insulation is mostly made of PVC or XLPE, the armor layer is mostly made of steel tape, and the outer sheath is mostly made of PVC. [0003] The first type of non-armoured OPLC optical fiber composite low-voltage composite cable, the conductor is made of electrical copper, and its density is 8.89 g / cm 3 , although copper has good electrical and mechanical properties, due to the high density of copper and the lack of resources, its price remains high, which leads to the high cost of the cable itse...
