Description

一种加强型铝合金抗压电缆
技术领域
本发明涉及电缆领域,尤其是一种加强型铝合金抗压电缆。
背景技术
众所周知,常规的铝合金电缆通常采用AA8000系列铝合金绞线作为导体,在导体外挤包绝缘层构成,而铝合金电缆的牵引强度为53MPa,远远低于铜导体电缆的70MPa;使用中常常发生拉断的情况。
现有技术菜采用支撑架对电缆进行支撑,通过增加支撑架的形式来保护同轴电缆,具有一定的效果,但增加了敷设成本和时间,加之电缆本身承载性能差,施工过程中难免会因为不慎操作造成电缆的线芯损坏的问题。
近年来,电缆企业普遍认识到了这种铝合金电缆自身的不足,都在不断的探索改进。
发明内容
本发明在于提供一种抗压强度高、机械强度高、防潮及密封性好、弯曲性好、降低了成本、延长了使用寿命的加强型铝合金抗压电缆。
为解决以上技术问题,本发明所述的一种加强型铝合金抗压电缆,包括管状铝合金导体,在管状铝合金导体的中心设有碳纤维复合加强芯,在碳纤维复合加强芯与管状铝合金导体之间设有薄铜带;在管状铝合金导体外挤包绝缘层,在绝缘层外缠绕由多根导电单线并列缠绕而成的单线层构成;在单线层外绕包缓冲层以及外护套;在缓冲层与外护套之间还设有金属抗压管。
所述碳纤维复合加强芯由多根细碳纤维复合丝束合或绞合而成。
所述的金属抗压管为绕包或纵包的硬质抗压管。
本发明防水铠装电缆有益效果要于:
1、使铝合金电缆自身的抗拉强度增加至同等截面的铜导体相当的水平,有效解决电缆被拉断的问题;
2、与铜电缆相比较,降低了材料成本,节约了铜资源;与铝电缆相比较,增加了抗拉强度、热稳定性等指标;大大延长了电缆的安全使用寿命;
3、在缓冲层与外护套之间还设有金属抗压管,使得电缆的机械强度高、抗压性能好,防潮及密封性好,轧纹可以改善其弯曲性能;
4、所述的单线层就相当于一个外导体,使得内、外导体处于同心位置,电磁能量局限在内外导体之间的介质内传播,因此具有衰减小,屏蔽性能高;
5、采用管状内导体可以节省金属材料、减轻电缆重量,在大功率、高频下,由于集肤效应,电流实际上只是沿着导体表面很薄的一层流动,管状内导体管壁厚度比电流的趋肤深度大,其射频电阻实际上是与实心导体完全一样。
附图说明
图1为本发明的结构示意图。
具体实施方式
下面结合附图对本发明作进一步阐述。
如图1所示,本发明的一种加强型铝合金抗压电缆,包括管状铝合金导体3,在管状铝合金导体3的中心设有碳纤维复合加强芯1,使铝合金电缆自身的抗拉强度增加至同等截面的铜导体相当的水平,有效解决电缆被拉断的问题;在碳纤维复合加强芯1与管状铝合金导体3之间设有薄铜带2;在管状铝合金导体3外挤包绝缘层4,在绝缘层4外缠绕由多根导电单线5并列缠绕而成的单线层构成;在单线层外绕包缓冲层6以及外护套8;在缓冲层6与外护套8之间还设有金属抗压管7,使得电缆的机械强度高、抗压性能好,防潮及密封性好,轧纹可以改善其弯曲性能。
本发明加强型铝合金电缆的制造方法,是将碳纤维复合芯放在绞合导体的中心位置或和绞层中任意位置,此复合加强芯可以是实心,可以是多根细碳纤维复合丝束合或绞合而成,碳纤维丝可以放置在一个固定位置,也可根据需要将多根细碳纤维复合丝分散放置在不同的位置(比如分散至单丝绞合的缝隙处);再继续绞合铝合金单丝,铝合金单丝相邻层的绞向应相反,铝合金导体的单丝直径和单丝根数可根据电力系统或满足相关标准中对导体电阻及其它电气的要求来确定,最后挤包绝缘层来实现碳纤维复合加强芯与铝合金单丝之间的良好组合,来实现前述发明目的。
上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调整,这些改进和调整也应视为本发明的保护范围。
