Description

一种中压风能软电缆
技术领域
本实用新型涉及一种中压风能电缆,特别是用于单机容量2MW及以上风力发电机组中,连接位于机舱后部中压变压器的高压侧和位于风力发电机塔筒底部的中压开关柜,耐扭转、耐寒、耐高温场所。 
背景技术
风力发电行业的快速发展,催生了对风力发电用电缆的需求。由于风力发电场的环境恶劣,风机使用年限较长,并且有些品种电缆还需随风机不断转动,对电缆的性能要求很高。国内许多生产企业进行了研发,已生产出耐低温、耐紫外线、耐油、抗耐扭曲的风力发电用电缆,但这些电缆大多是1.8/3kV及以下电压等级电缆,对于额定电压26/35kV中压耐扭曲风能电缆,国内还没有企业生产。 
实用新型内容
本实用新型的目的旨在提供一种电压等级更高,性能更好的中压风能软电缆,以满足风能发电所需要传输大容量的需要。 
本实用新型的技术方案如下:包括镀锡铜丝导体,镀锡铜丝导体外设置有导体屏蔽层,导体屏蔽层外设置有乙丙橡皮绝缘层,乙丙橡皮绝缘层外设置有绝缘屏蔽层,绝缘屏蔽层外包裹有金属编织屏蔽层,金属编织屏蔽层外设置有护套层。所述的一种中压风能软电缆,所述的绝缘层为二元乙丙橡胶。所述的编织金属屏蔽层为镀锡铜丝,所述的护套层为硅橡胶。 
本实用新型的有益效果是:通过对电缆结构的重新设计,导体屏蔽层、绝缘层和绝缘屏蔽层采用一次性挤出保证绝缘和屏蔽的紧密无间隙结合,防止污染,从而避免电缆在高电场下的游离放电现象,有效降低了局部放电水平,绝缘性能更佳,采用二元乙丙橡皮做绝缘提高了电缆的使用温度和使用寿命。护套材料采用高性能硅橡胶材料,使电缆整体具有耐高低温性能,在-55℃~+50℃范围内可以安全使用,满足了风机用电缆需要。 
附图说明
图1为本实用新型的结构示意图。 
具体实施方式
参见附图,一种中压风能软电缆,包括有镀锡铜丝导体1,镀锡铜丝导体1外设置有导体屏蔽层2,导体屏蔽层2外设置有乙丙橡皮绝缘层3,乙丙橡皮绝缘层3外设置有绝缘屏蔽层4,绝缘屏蔽层4外包裹有金属编织屏蔽层5,金属编织屏蔽层5外设置有护套层6。
