Description
技术领域
本实用新型涉及一种风力发电设备用柔性控制电缆。
背景技术
冈能的清洁性、可再生性、资源广泛性使其备受瞩目,成为所有新能源中最具规模、技术最成熟、最有商业发展前景的发电模式。风力发电正在成为世界上增长最快的能源项目。中国风能储量丰富,分布广阔,对发展风力发电有着广阔的市场前景。由于风能发电一般都建在沿海岛屿、边远山区和地广人稀的大草原,成年累月接受大风大雨的洗礼和烈日炎炎的暴晒及冰雪冬日的严寒考验。风力发电的环境恶劣,风机使用年限要求较长,且电缆随风机不断旋转,因此对风力电缆的性能要求较高。我国风力发电专用电缆主要依靠进口,特别是控制系统用电缆,风力发电设备用柔性控制电缆的国产化迫在眉睫。
实用新型内容
本实用新型目的是为了克服现有技术的不足,提供一种抗扭绞、耐环境性能优异的风力发电设备用柔性控制电缆。
本实用新型包括缆芯,在所述缆芯外侧依次设置阻水带绕包层、镀锡铜丝编织屏蔽层、芳纶纤维编织加强层和外护套层;所述缆芯由四组绝缘线芯和填充层绞合而成;每组所述的绝缘线芯分别包括多根同向绞合的退火镀锡软铜丝束绞导体,在绞合后的多根退火镀锡软铜丝束绞导体外侧依次设置隔离层和乙丙橡胶绝缘层。
本实用新型采用若干根数退火镀锡软铜丝,先束合成股线后再采用复绞的方式绞合而成,束绞、复绞均采用同向绞合,可提高电缆的柔软度和耐扭曲、弯曲性能;隔离层采用深灰色超薄聚酯带,厚度在0.04-0.05mm之间,搭盖率30%,超薄型的设计可以减少外径尺寸;绝缘层采用改性乙丙橡胶材料,具有优异的电绝缘性能和耐电晕性能,同时还具有耐气候、耐臭氧、耐热、耐酸碱等特性,且材质柔软;芳纶纤维编织承重加强层,一方面保证其具有较好的抗拉作用,另一方面在电缆扭转过程中,增强了缆芯与外护层之间的相对滑移性,减少了缆芯与外护层之间的摩擦力,有利于延长使用寿命;外护套层采用氯化聚乙烯材料,使产品具有优异的耐扭、耐臭氧性、耐大气老化性、耐化学腐蚀性及耐热、耐低温性、耐油性、阻燃性等。
本实用新型作为一种风力发电设备用柔性控制电缆,在复杂场合下具有良好的防电磁干扰、抗扭转、环保、耐油、防紫外线,同时具有控制信号、电能传输双重功能和柔软性。
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,本实用新型包括缆芯1,在所述缆芯1外侧依次设置阻水带绕包层2、镀锡铜丝编织屏蔽层3、芳纶纤维编织加强层4和外护套层5;所述缆芯1由四组绝缘线芯6和填充层7绞合而成;每组绝缘线芯6分别包括多根同向绞合的退火镀锡软铜丝束绞导体8,在绞合后的多根退火镀锡软铜丝束绞导体8外侧依次设置隔离层9和乙丙橡胶绝缘层10。
