Abstract

本实用新型公开了电缆技术领域内的船用防爆电缆,包括至少两组对绞线,每组对绞线与一根内引流线相绞合,在绞合后的外周设有内屏蔽层,带有屏蔽层的对绞线与一根外引流线一起构成电缆束,电缆束外设有外屏蔽层,外屏蔽层外设有内护套,内护套外设有铠装层,铠装层外设有外护套。本实用新型中,内引流线可保证单股对绞线外侧在长度方向上电势相等,外引流可保证多股对绞线在长度方向上的电势相等,也能保证内屏蔽层和外屏蔽层可靠接地,可避免发生对地放电现象,起到良好的防爆作用;内、外屏蔽层的设置,避免了外电场的干扰及内电场的相互干扰,保证了电缆稳定传输,该电缆可应用在船舶、海上石油平台等需要防爆的场所。

Description

船用防爆电缆
技术领域
本实用新型涉及一种电缆,特别涉及一种船用电缆。
背景技术
现有技术中的船用电缆,一般包括有芯线导体,在芯线导体设有设有绝缘层,多根带有绝缘层的芯线导体集成一束,在其外周设有绕包层,绕包层外设有护套,有的在护套外还设有铠装层,这种电缆抗拉强度大,但其结构简单,屏蔽效果差,同时,电缆长度方向上会形成电势差,容易对地放电,产生电火花,其防爆性差,不能应用在油气、粉尘浓度大的场所。
实用新型内容
本实用新型的目的是提供一种船用防爆电缆,使电缆具有良好的防爆功能。
本实用新型的目的是这样实现的:船用防爆电缆,包括至少两组对绞线,每组对绞线与一根内引流线相绞合,在绞合后的外周设有内屏蔽层,带有屏蔽层的对绞线与一根外引流线一起构成电缆束,电缆束外设有外屏蔽层,外屏蔽层外设有内护套,内护套外设有铠装层,铠装层外设有外护套。
本实用新型中,内引流线可保证单股对绞线外侧在长度方向上电势相等,外引流可保证多股对绞线在长度方向上的电势相等,也能保证内屏蔽层和外屏蔽层可靠接地,这样可避免发生对地放电现象,起到良好的防爆作用;内屏蔽层和外屏蔽层的设置,避免了外电场的干扰,同时,也可以避免内电场的相互干扰,保证了电缆稳定传输,铠装层使电缆具有高强度,抗拉性好,该电缆可应用在船舶、海上石油平台等需要防爆的场所。
附图说明
图1为本实用新型结构示意图。
其中,1外护套,2铠装层,3内护套,4外屏蔽层,5内屏蔽层,6对绞线,7内引流线,8外引流线。
具体实施方式
如图1所示,为本实用新型的船用防爆电缆,包括有六组的对绞线6,每组对绞线6包括有两根外带绝缘的芯线导体,每组对绞线6与一根内引流线7相绞合,在绞合后的外周设有内屏蔽层5,带有屏蔽层的对绞线6与一根外引流线8一起构成电缆束,电缆束外设有外屏蔽层4,外屏蔽层4外设有内护套3,内护套3外设有铠装层2,铠装层2外设有外护套1。
本实用新型并不局限于上述实施例,所述对绞线可至少为两组。
