Description

一种陶瓷化油田及海上平台耐火电缆
技术领域
本实用新型涉及电缆技术领域,尤其涉及一种陶瓷化油田及海上平台耐火电缆。
背景技术
随着社会发展的不断进步,人们对安全防护的要求不断提高。在耐火电缆领域,人们对耐火电力电缆在火灾中持续供电能力也有着越来越高的要求,耐火电力电缆的绝缘性能对其火灾中持续供电能力有着重要影响。
实用新型内容
本实用新型目的就是为了弥补已有技术的缺陷,提供一种陶瓷化油田及海上平台耐火电缆。
本实用新型是通过以下技术方案实现的:
一种陶瓷化油田及海上平台耐火电缆,包括有导体,在导体的外侧依次包覆有陶瓷化硅橡胶云母带和绝缘层,将三根导体束绞后在外侧依次包有填充层、绕包低烟无卤带、挤出隔氧层、双层镀锌钢带铠装层和低烟无卤外护套。
所述的绝缘层为低烟无卤阻燃交联聚烯烃绝缘层;所述的填充层为无卤阻燃填充绳;所述的绕包低烟无卤带为低烟无卤阻燃玻璃布带。
陶瓷化油田及海上平台耐火电缆作为一种新型结构电缆,其耐火层材料具有优异的绝缘性能、优异的阻燃性和耐火性以及良好的工艺性能。该耐火层材料可以直接绕包在导体表面,在垂直和水平燃烧下不延燃,阻燃性可VW-1级,氧指数可达43以上。在350-3000℃有焰、无焰情况下,能烧成坚硬的陶瓷状铠体,温度越高、烧;蚀时间越长烧后的陶瓷状铠体越坚硬,残余物为环保的陶瓷无机物,残余量可达80%以上,不脱落,陶瓷状铠体可以起到很好的隔火隔热效果。因此将被广泛应用于海上平台、石油开采、冶金、化工、矿井、煤窑等危险、高温环境。
本实用新型的优点是:本实用新型使用了陶瓷化硅橡胶云母带直接包在导体的外侧,具有绝缘和阻燃双重效果,具有高效、环保、经济、耐超高温的优点。
附图说明
图1为本实用新型的结构示意图。
具体实施方式
如图1所示,一种陶瓷化油田及海上平台耐火电缆,包括有导体1,在导体1的外侧依次包覆有陶瓷化硅橡胶云母带2和绝缘层3,将三根导体1束绞后在外侧依次包有填充层4、绕包低烟无卤带5、挤出隔氧层6、双层镀锌钢带铠装层7和低烟无卤外护套8。
所述的绝缘层3为低烟无卤阻燃交联聚烯烃绝缘层;所述的填充层4为无卤阻燃填充绳;所述的绕包低烟无卤带5为低烟无卤阻燃玻璃布带。
