Abstract

本发明属于一种将电力输电用架空绝缘电缆、光缆、射频电缆、通信电话电缆融合的架空绝缘电缆，确切的说是一种软弹性复合型架空绝缘电缆。现今应用的架空复合缆其电缆与光缆连接筋为刚性连接，由于弧垂和凤舞等原因造成受力不均，导致连接筋撕裂，并向绝缘层延伸，易使导体外漏。而且连接筋过于厚实，不易使光缆和电缆分离。本发明目的在于提供一种软弹性复合型架空绝缘电缆，其特征是将光缆、射频电缆、通信电话电缆其中一种或几种电缆作为架空绝缘电缆的附加电缆与电力输电用架空绝缘电缆用有间隔孔的软弹性连接筋连接合并应用，以解决现有问题。本发明施工方便，不需特殊维护，适合多网合一的新型电力传输模式。

Description

软弹性复合型架空绝缘电缆
技术领域
本发明属于一种将电力输电用架空绝缘电缆、光缆、射频电缆、通信电话电缆融合的架空绝缘电缆，确切的说是一种软弹性复合型架空绝缘电缆。 
背景技术
现今的光纤复合架空绝缘电缆，如中国专利200920231879.5光纤复合架空绝缘电缆，201020512395.0平行集束型光纤复合低压架空绝缘电缆，只将光纤或光缆与电力电缆合并使用，并未完全达到电力输电电缆、光缆、射频电缆、通信电话电缆同时应用的效果。其电缆与光缆连接筋为刚性连接，由于弧垂和凤舞等原因将造成受力不均，导致连接筋变形过度造成撕裂，开裂向绝缘层延伸，易产生使导体外漏的趋势。而且连接筋过于厚实，在终端连接的施工中不易使光缆和电缆分离。 
发明内容
本发明目的在于提供一种软弹性复合型架空绝缘电缆，其特征是将光缆、射频电缆、通信电话电缆其中一种或几种电缆作为架空绝缘电缆的附加电缆与电力输电用架空绝缘电缆用有间隔孔的软弹性连接筋连接合并应用，以解决上述问题。 
本发明目的由以下方法实现 
将有防护层和外护套的附加电缆用有间隔孔的软弹性连接筋与有内屏蔽和外绝缘的电力输电导体连接合并应用，组成软弹性复合型架空绝缘电缆，附加电缆为光缆、射频电缆、通信电话电缆的其中一种或几种电缆。 
由于采用了上述方案，使得本发明在使用中完全达到电力输电电缆、光缆、射频电缆、通信电话电缆同时应用的效果，节约了电缆敷设空间；软弹性连接筋可以缓冲弧垂和凤舞等原因造成的过度变形，且软弹性连接筋施工时易于切割分离。 
下面结合附图对本发明做详细说明： 
附图说明
图1、图2是本发明单侧型软弹性复合型架空绝缘电缆实施方案的两个实施例的纵剖面示意图。
图3、图4是本发明双侧对称型软弹性复合型架空绝缘电缆实施方案的两个实施例的纵剖面示意图。 
1.导体 2.内屏蔽 3.外绝缘 4.软弹性连接筋 5.防护层. 6.附加电缆 7.外护套8.间隔孔 
具体实施方式
将有防护层5和外护套7的附加电缆6用有间隔孔8的软弹性连接筋4与有内屏蔽2和外绝缘3的电力输电导体1连接合并应用，组成软弹性复合型架空绝缘电缆，附加电缆7为光缆、射频电缆、通信电话电缆的其中一种或几种电缆； 
导体1用于电力传输；内屏蔽2用于均匀导体电场分布；外绝缘3用于导体1与外界绝缘；防护层5和外护套7用于保护附加电缆6；软弹性连接筋4由易于切割和撕裂的材料制成，用于连接附加电缆6，并有纵向和横向的弹性以缓冲弧垂和舞动变形；间隔孔8也用于延缓纵向和横向的变形，且易于电缆的通风，并有使天然降水流失的作用。 
电力输电导体可由电工铝，高纯铝，银包铝，铝合金，电气、电工用铜，银包铜等导电材料或金、铂等贵金属材料制成；内屏蔽由电缆用半导体材料制成；绝缘层可由有绝缘介质特性的热塑性塑料，工程塑料制成；软弹性连接筋可由软质热塑性塑料，软质热塑性橡胶、软质橡塑共混材料、软质工程塑料制成；外护套由电缆用外护套材料制成；防护层由电缆包带等阻水隔热材料制成；附加电缆可为光缆、射频电缆、通信电话电缆其中一种或几种电缆。
