具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
需要说明的是，当组件被称为“固定于”另一个组件，它可以直接在另一个组件上或者也可以存在居中的组件。当一个组件被认为是“连接”另一个组件，它可以是直接连接到另一个组件或者可能同时存在居中组件。当一个组件被认为是“设置于”另一个组件，它可以是直接设置在另一个组件上或者可能同时存在居中组件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及/或”包括一个或多个相关的所列项目的任意的和所有的组合。
为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图对本发明的具体实施方式做详细的说明。其中，本发明实施例结合示意图进行详细描述，在详述本发明实施例时，为便于说明，所述示意图只是示例，其在此不应限制本发明保护的范围。
海底光缆敷设安装和工作在肉眼不可见的海底，时刻承受着海水水压，其抗水压性能是工作可靠性的重要指标之一。这些海缆和水下设施还会受地震、锚拉等自然和人为因素的破坏，一旦破损或断裂，在水压作用下，海水会沿海缆和水下设施的轴向两端渗透，扩大故障面，增加维护成本。此外，海水中的化学成分还会具有腐蚀性，因此，海底光缆需要具有良好的抗拉、 抗压强度和耐腐蚀性。
为了满足海底光缆的高抗压性能，本揭露提供的海底光缆采用具有多层防护层的骨架式结构，在提升光纤芯数的同时提供强有力的支撑及防护保护。设置在所述海底光缆外围的护套层、铠装层及外被层能提供良好的耐腐蚀性及抗压抗拉性能。
请参阅图1所示，本发明实施方式提供的一种海底光缆1包括中心加强件10、导体12、骨架14、光单元16、阻水带18、金属层20、护套层22、铠装层24及外被层26。
其中所述中心加强件10位于中心位置，在所述中心加强件10外包覆所述导体12，在所述导体12外挤塑所述骨架14，在所述骨架14内填充所述光单元16，在所述骨架14外绕包所述阻水带18，在所述阻水带18外包覆所述金属层20，在所述金属层20外挤塑所述护套层22，在所述护套层22外绞合所述铠装层24，在所述铠装层24外设有所述外被层26。
所述中心加强件10用于提供中心支撑作用，以为设置在所述中心加强件10外的所述导体12提供支撑。所述中心加强件10可采用具有一定强度的材质。在一些实施例中，所述中心加强件10采用钢丝、非金属增强材料或其他等效增强材料绞合而成，例如采用多层钢丝绞合，或采用多层非金属增强材料绞合。其中所述绞合层数可为1层、2层或3层或多层，可根据强度需要进行设置。所述非金属增强材料可为纤维增强复合材料(Fiber Reinforced Polymer/Plastic，FRP)，例如CFRP、GFRP、AFRP、BFRP等。FRP复合材料是由纤维材料与基体材料(树脂)按一定的比例混合后形成的高性能型材料，质轻而硬，不导电，机械强度高，耐腐蚀。
所述导体12用于传输电能，在一些实施例中，可用于高压电能传输，例如110kv以上的高压电能。在一些实施例中，所述导体12可采用铜、铝 等导电材料，采用纵包、绕包或无缝焊接的方式设置在所述中心加强件10上。在本实施例中，所述导体12采用铜带纵包或铜管无缝焊接成型。设置导体12是为了能够实现电能传输。
在一些实施例中，骨架14采用绝缘且阻水性强的材料，例如高密度聚乙烯绝缘料或聚氯乙烯(Polyvinyl chloride，PVC)等。骨架槽数可为2至18中的任意一个自然数，每个骨架槽容纳一个光单元16，所述骨架槽内填充阻水油膏，以进一步提升阻水性能。
所述光单元16用于容纳光纤。在一些实施例中，所述光单元16能容纳的光纤芯数可为1至96中任意一个自然数。所述光单元16采用高强度的材质制成。在一些实施例中，所述光单元16采用不锈钢管焊接成型，所述不锈钢管内填充阻水油膏。不锈钢管相较PVC塑料松套管，具有更优良的抗压抗冲击性能。
光缆用阻水带通过产品内部呈均匀分布的高吸水性材料(例如树脂)所具有的强有力的吸水性能，高吸水性材料能快速吸入数倍于自重的水。并且，阻水材料一旦遇水就会即刻膨胀变成凝胶，此时不管给其施加多少压力，水分也不会被挤出。因此，用含吸水性材料的阻水带包覆所述骨架14，万一光缆外壁破损，伤口部分的高吸水性材料因膨胀而发挥密封效果，可以将水的进入阻止到最小限度。因此，所述阻水带18包覆在所述骨架14上，能够起密封、防水、隔潮和缓冲防护作用。在一些实施例中，所述阻水带18采用高性能阻水带，具备良好的阻水性、抗拉强度和热稳定性能。所述阻水带18可采用任意适宜的方式设置在所述骨架14上，例如阻水带采用绕包绑扎的方式绑扎在所述骨架14上。
所述金属层20设置在所述阻水带18外侧，可进一步提供电磁屏蔽和阻水防护作用。在一些实施例中，所述金属层20采用铅套、皱纹铝套或铝塑 复合带。
所述护套层22设置在所述金属层20外侧，主要提供防护作用，可采用较为坚固的非金属材质。在一些实施例中，所述护套层22采用聚乙烯材料或PVC材料。
所述铠装层24设置在所述护套层22外侧，进一步提供防护及支撑作用。在一些实施例中，所述铠装层24可采用钢丝、铜丝等金属材料、或非金属增强材料(例如PVC)或其他等效增强材料绞合而成。其中，铠装钢丝可为多种规格的锌铝镁镀层的高强钢丝。可以理解的是，在一些实施例中，也可以同时采用几种不同材质的铠装层，例如，在所述护套层22外设置一层铜丝铠装层，在所述不锈钢铠装层外设置一层不锈钢铠装层。所述铠装层的层数可根据需要设置，例如可为1层、2层、3层、4层等。所述铠装层的间隙可填充阻水沥青或阻水油膏，以进一步提高阻水抗压防护性能。
在一些实施例中，所述护套层22、及/或所述铠装层24也可采用非金属增强材料，例如上所述的纤维增强复合材料FRP。在一些实施例中，所述铠装层24也可以采用钢丝等金属铠装层与非金属增强材料铠装层结合的方式设置。
所述外被层26设置在所述铠装层24外侧，进一步提供防护作用。在一些实施例中，所述外被层26为缠绕聚丙烯绳或挤塑聚乙烯材料，或PVC材料。
所述骨架14采用绝缘材料，可作为所述导体12的绝缘层。可以理解的是，在一些实施例中，所述导体12外侧还可进一步设置绝缘层、电磁屏蔽层等以进一步提升绝缘及电磁屏蔽性能。
采用本发明的海底光缆，采用骨架式海底光电复合缆，光纤容量大，实现单根海底光缆光纤芯数由上百芯提升至上千芯。骨架的中心加强件外包覆 导体，可作为电能传输，同时骨架材料选用高密度聚乙烯绝缘料，可用于高电压传输的绝缘保护；骨架槽内光单元均采用不锈钢光单元，可有效保护光纤，护套层以及铠装层实现支撑结构，有效提升骨架式海底光电复合缆抗冲击、压扁性能，该缆型阻水结构可有效保证纵向及横向阻水。
另外，对于本领域的普通技术人员来说，可以根据本发明的技术构思做出其它各种相应的改变与变形，而所有这些改变与变形都应属于本发明权利要求的保护范围。
