Abstract

一种具有良好阻水功能的海洋石油勘探用探测电缆,包括缆芯及外护套,缆芯内具有传输导线,在缆芯中央设有芳纶加强件,在缆芯内还设有聚烯烃填充绳和阻水油膏,在缆芯与外护套之间设有阻水带层。本实用新型由于在缆芯中央设有用抗拉强度高、比重小的芳纶纱制成的加强件,缆芯内还设有聚烯烃填充绳,既提高了电缆的抗拉强度,又使电缆的重量较轻;由于在缆芯内设有阻水油膏,在缆芯与外护套之间设有阻水带层,使电缆在纵向和横向全方位都能阻水,阻水性能增强,能够适应在海水中长时间使用。因此,本实用新型用于海洋石油勘探作为探测电缆不易渗水、不易受损、使用寿命长。

Description

具有良好阻水功能的海洋石油勘探用探测电缆
技术领域
本实用新型涉及一种信号传输电缆,尤其是一种海洋石油勘探用的探测电缆。
背景技术
海洋石油勘探用探测电缆,由于使用环境恶劣、复杂,又长时间处于海水中,要求电缆具有较高的抗拉强度,在纵向和横向全方位都能阻水,而且重量较轻,现有这种电缆的性能难以适应这些要求,使用中易渗水、易损坏,影响使用寿命。
发明内容
为了克服现有海洋石油勘探用探测电缆的不足,本实用新型的目的是提供一种具有良好阻水功能的海洋石油勘探用探测电缆,抗拉强度较高,阻水性能好,而且重量较轻,能够适应海洋中恶劣、复杂的使用环境,不易渗水、不易损坏,使用寿命长。
本实用新型提供的一种具有良好阻水功能的海洋石油勘探用探测电缆,包括缆芯及外护套,缆芯内具有传输导线,在缆芯中央设有芳纶加强件,在缆芯内还设有聚烯烃填充绳和阻水油膏,在缆芯与外护套之间设有阻水带层。
本实用新型的有益效果是:由于在缆芯中央设有用抗拉强度高、比重小的芳纶纱制成的加强件,缆芯内还设有聚烯烃填充绳,既提高了电缆的抗拉强度,又使电缆的重量较轻;由于在缆芯内设有阻水油膏,在缆芯与外护套之间设有阻水带层,使电缆在纵向和横向全方位都能阻水,阻水性能增强,能够适应在海水中长时间使用。因此,本实用新型用于海洋石油勘探作为探测电缆不易渗水、不易受损、使用寿命长。
附图说明
图1是本实用新型的横截面示意图。
在图1中,1、传输导线,2、导体,3、绝缘层,4、芳纶加强件,5、聚烯烃填充绳,6、缆芯,7、阻水带层,8、外护套,9、阻水油膏。
具体实施方式
参照图1,在由多根铜丝束绞而成的导体2外包覆绝缘层3制成传输导线1;将四根传输导线1和置于四根传输导线1之间的中央的芳纶加强件4、置于四根传输导线1相邻外侧的间隙内的聚烯烃填充绳5、阻水油膏9一起绞合制成缆芯6;在缆芯6外依次包覆用双面阻水带制成的阻水带层7、外护套8,即制成本实用新型。
