Description

一种隔热型电缆
技术领域
本发明涉及电力电缆领域，尤其是指一种隔热型电缆。
背景技术
目前，随着我国社会经济的发展，电缆用量迅速增长，对电缆的质量要求也不断的 提高，比如在计算机、机房等领域内使用的电缆，对电缆的耐高低温性能、耐油、耐机械损 伤、抗干扰性能等方面要求都特别高。只有符合要求，才能更好保证电缆的生产使用。
现有技术的电缆，虽然耐火性能好，但隔热效果有限、弯曲性差，影响电缆正常运 行的载流量。
现有技术的电缆，电缆缆芯容易松动，受到挤压或者弯折时，容易断芯，使得电缆无法工作。
发明内容
本发明所要解决的技术问题是提供了一种重量轻、耐高温、热稳定性好、导热率低、比热小、隔热型电缆。
本发明所述的一种隔热型电缆，包括缆芯，在缆芯外挤包内护套和外护套；所述的缆芯由三角形支架、三根互挤设置在三角形支架内的绝缘线芯以及位于三角形支架三个顶角处的地线构成；在三角形支架与内护套之间设有陶瓷纤维丝；在内护套与外护套之间依次设有厚度为2-5mm的弹性缓冲层、厚度为2-4mm的金属铠装层以及厚度为3-6mm的岩棉隔热层。
进一步改进，所述的绝缘线芯由铝导体、依次挤包在铝导体外的绝缘层、绝缘屏蔽层以及设置在绝缘屏蔽层外的硅胶防火套管构成。
进一步改进，所述的金属铠装层为铝包铜铠装层。
本发明的有益效果在于:
1、本发明的缆芯中设有三角形支架，起到对绝缘线芯的保护作用，使得线芯不易折断；
2、本发明设有陶瓷纤维丝，不仅使得电缆具有重量轻、耐高温、热稳定性好、导热率低、比热小及耐机械震动，还具有抗熔触铝，锌等有色金属侵蚀能力；
3、电缆还设有岩棉隔热层，使得电缆的绝热隔热性能好，在常温条件下（25℃左右）的热导率通常在0.03～0.047W/(moK)之间；
4、本发明的绝缘线芯最外层套有硅胶防火套管，使得电缆具有耐高温性能，保温隔热性能，阻燃性能，电绝缘性能，化学稳定性能，耐气候老化性能，耐寒，耐水，耐油，耐臭氧，耐电压、耐电弧、耐电晕性能等，特别是安全环保性能，是石棉等危害性制品的最佳替代产品；硫化后可在-65°C - 260°C温度范围内长期使用并保持其柔软弹性性能。
附图说明
图1是本发明的结构示意图。
具体实施方式
如图1所示，本发明所述的一种隔热型电缆，包括缆芯，在缆芯外挤包内护套8和外护套12；所述的缆芯由三角形支架1、三根互挤设置在三角形支架内的绝缘线芯以及位于三角形支架1三个顶角处的地线2构成；所述的绝缘线芯由铝导体3、依次挤包在铝导体外的绝缘层4、绝缘屏蔽层5以及设置在绝缘屏蔽层外的硅胶防火套管6构成；在三角形支架1与内护套8之间设有陶瓷纤维丝7，不仅使得电缆具有重量轻、耐高温、热稳定性好、导热率低、比热小及耐机械震动，还具有抗熔触铝，锌等有色金属侵蚀能力；在内护套8与外护套12之间依次设有厚度为2-5mm的弹性缓冲层9、厚度为2-4mm的金属铠装层10以及厚度为3-6mm的岩棉隔热层11，使得电缆的绝热隔热性能好，在常温条件下（25℃左右）的热导率通常在0.03～0.047W/(moK)之间。
本发明提供了一种隔热型电缆的思路及方法，具体实现该技术方案的方法和途径很多，以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。本实施例中未明确的各组成部份均可用现有技术加以实现。
