Abstract
一种光纤电缆,特别是一种架空电缆在其外护套(3)内,具有4或5个加强元件(1),在由加强元件(1)所形成的间隙空间内装容有至少一根光纤束(6、6.1),这种电缆的结构对于被安装在相距远达1000米的铁塔上来说,具有足够的拉伸强度。
Description
本发明涉及一种光缆,尤其是涉及那种已知为架空电缆类的光缆,这种架空电缆设计成能自由地悬架在相距远达1千米的间隔的支承物上。
在其最广阔的领域内,本发明包括这样一种光缆,该光缆在一外护套内至少有三个纵向延伸的加强元件,在这些加强元件中间至少有一个间隙空间,在该空间中松弛地容纳着一包括有多根光纤的光纤束件。
光纤可以是一绞合光纤束,或是一光纤带、或叠在一起的多条光纤带,或其他通常的结构型式。
光纤束件最好包容在一管子内,该管子的尺寸能容许光纤在其里面一定程度的横向移动,该管子内最好充有如油脂那样的阻塞水的物质。阻塞水的物质也可以充填在相邻加强元件之间的空隙内和加强元件与外护套之间的空隙内。
用作为一架空电缆,该加强元件当然必然能对电缆的拉伸提供足够的抵抗力,以防当电缆悬架在相隔距离为其最大的设计距离的二支撑物之间时作用在光纤上的不适当的应力。
并且,对架空电缆来说,对给定的加强元件的总的截面积,特别希望其具有最小的外径,同时却具有足够的间隙空间来容纳光纤束。
我们发现对圆形横截面的加强元件来说,一般有四或五个加强元件。这些加强元件最好是由玻璃增强塑料或其他适宜的高分子材料绞合在一起成螺旋状结构形成。
在一装有4个圆截面的加强元件的架空电缆中,光纤束一般在由相邻的加强元件与包围在外面的外护套的内表面之间形成的空隙通道中围绕加强元件而绞合。这些通道具有这样的高度,使得光纤束与外护套的内表面分离开。这样在电缆安装和使用时,能保护光纤抵御外部压力。
加强元件的直径例如可以是约为5毫米,这可以许可一个外径约为2毫米,并容纳例如是4根光纤的管子被装容在所述的空隙通道内而不与外护套的内表面相接触。在这种情况下,可在4个绞合的加强元件之间的中央通道内设置一减震缓冲元件。
在使用五个加强元件的情况下,光纤一般装容在由加强元件包围而成的中央通道内。
现在参阅附图1和附图2,通过举例说明根据本发明的架空电缆的二种变换形式。附图中示出了二种电缆形式的横截面。
首先参阅图1,图中示出了包括有4个圆形横截面的加强元件1的电缆,这些加强元件由玻璃增强塑料材料制成,每个直径约为5毫米,围绕一中心减震缓冲垫料2而绞合在一起。垫料2由聚乙烯制成,直径约为2毫米。加强元件被包围在一紧密贴合的聚乙稀或其他聚合物外护套3内,护套3的壁厚约为1.5毫米。
在形成在相邻的各对加强元件1之间的四个通道4内,放有4根光纤元件5,每根包括有一由合适的聚合物制成的直径为2毫米的管子7,管子7内有一由4根单根形式光纤6组成的光纤束,并充有油脂或其他阻塞水的化合物,使能允许光纤在管内一定程度的横向移动。通道4具有这样的高度,使得光纤元件5能与包围在外面的护套3的内表面相隔开,从而保护抵御外部压力。
在加强元件1,光纤元件5和护套3之间的间隙空间中也可以充填适当的阻塞水的化合物,以免水份沿着电缆渗入。
外护套可以容有一适当的垫料,以提供一个足够强度的抵抗力。
图2中所示的第2种电缆包括五个绞合在一起的加强元件1,类似于图1所示电缆的加强元件,并同样由一聚乙烯外护套3包围。
在这一实施例中,由相邻的加强元件1与护套3内表面之间空隙形成的通道的大小,不足以装容具有上述实施例中那样直径的光纤元件而不与外护套接触。在这种情况下,16根光纤6.1被装容在一单根聚合物管子8内,管子8的直径约为3.25毫米,位于由绞合的加强元件1所包围的中央通道9内。管子8内充有能允许光纤在管内移动的油脂或其他适宜的阻塞水的化合物,(如上述实施例),在加强元件1,管子8和护套3之间的空隙内也可以充有阻塞水的化合物。光纤6.1可以绞合在一起,或以4×4的排列叠放在一起或设置成任何其他通道的形式。
光纤如同前一个实施例一样受到保护以抵御外部压力。
在有些情况下,加强元件可以包一层塑料材料,给予另外的机械和/或环境保护。
