Description

高强度聚酰胺防海水电缆
技术领域
本发明涉及电缆技术领域，具体为高强度聚酰胺防海水电缆。
背景技术
随着海洋经济的逐步发展，人们对海洋的认识和了解不断深入，海上通信/海上石油开发都需要与之配套的电缆产品，另外国防建设也需要将大量的通信器材埋在海底，所用的埋设机设备(水下机器人)要求相关的系缆来完成。
因海底恶劣复杂的环境，现有的大多数常规型号的防水电缆无法承受海水的压力；以及海水的腐蚀，导致电缆的绝缘层破损，造成电缆的电压不稳定，导致电缆被击穿，缩短电缆的使用寿命，增加经济成本。
发明内容
为了解决上述技术问题，本发明提出了高强度聚酰胺防海水电缆。
本发明所要解决的技术问题采用以下技术方案来实现：
高强度聚酰胺防海水电缆，包括导线、由内而外依次包覆在导线外的绝缘层、屏蔽层、耐腐蚀层、铜合金管套、沥青涂层，所述绝缘层为聚酰胺绝缘层，所述绝缘层与屏蔽层之间设有以提高电缆强度的抗压骨架。
进一步地，所述抗压骨架上均布有穿过屏蔽层、耐腐蚀层与铜合金管套抵合的抗压支架。
进一步地，所述抗压骨架及抗压支架采用不锈钢材料。
进一步地，所述屏蔽层采用镀锡铜丝材料。
进一步地，所述耐腐蚀层采用聚乙烯材料。
本发明的有益效果是：
与现有技术相比，本发明通过聚酰胺绝缘层来提高电缆的绝缘性能以及耐击穿性能，另外聚酰胺绝缘层还能够提高电缆的机械强度和韧性；通过不锈钢抗压骨架来提高电缆的强度，增强电缆的抗压强能力，提高了电缆的使用寿命。
附图说明
下面结合附图和实施例对本发明进一步说明：
图1为本发明的结构示意图。
具体实施方式
为了使本发明实现的技术手段、创作特征、达成目的与功效易于明白了解，下面结合附图以及实施例对本发明进一步阐述。
如图1所示，高强度聚酰胺防海水电缆，包括一根导线1，由内而外依次包覆在导线1外的绝缘层2、屏蔽层4、耐腐蚀层5、铜合金管套6、沥青涂层7；其中所述绝缘层2为聚酰胺绝缘层，聚酰胺具有优良的电绝缘性能以及耐击穿电压高，非常适用于海底大功率电缆；所述屏蔽层4为采用镀锡铜丝材料钩织而成的镀锡铜丝网管，其具有屏蔽、柔韧性好、比重轻等性能；所述耐腐蚀层5为采用聚乙烯材料制成的耐腐蚀管，聚乙烯具有优异的化学稳定性，能够有效地承受海水的腐蚀；所述铜合金管套6的作用一是起到加强电缆的机械强度，二是增强电缆的耐腐蚀性能。
所述绝缘层2与屏蔽层4之间设有抗压骨架3，所述抗压骨架3上圆周均布有四个穿过屏蔽层4、耐腐蚀层5与铜合金管套6内管壁抵合的抗压支架8，所述抗压骨架3及抗压支架8均采用不锈钢材料制成，通过抗压支架8支撑铜合金管套6的内管壁，从内部加强了电缆的抗压能力；同时包覆在聚酰胺绝缘层2外部的抗压骨架3保证了即使抗压支架8和外层的铜合金管套6被压变形的情况下，内部的导线1仍能够正常使用，大大提高了电缆的使用寿命和多种环境的适应性。
以上显示和描述了本发明的基本原理、主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
