Technical Problem

如果沿用现有的整段光单元开剥并分离的方式,需要在施工现场开剥超过100米的长度,施工人员需频繁的上下塔进行开剥及熔纤操作,极大增加了现场施工的危险性,降低了施工效率

Benefits of technology

[0038]1)本发明的OPGW的绝缘光单元的分段绝缘引下结构,将OPGW的引下部分的一段去除金属绞丝来显露出一部分的绝缘光单元,并对去除金属绞丝后的这部分进行绝缘化处理,以达到对OPGW局部分段绝缘化处理的目的,显露的这部分绝缘光单元与金属绞丝分离后通过骨架和保护套进行机械保护,并且通过骨架和保护套实现上绞合部与下绞合部的绝缘,隔开带电的上绞合部和需要进行后续处理的下绞合部,使下绞合部后续在剥离绝缘光单元时不受带电的上绞合部的影响,便于下绞合部剥离出绝缘光单元。

Abstract

The application discloses a segmented insulation lead-down structure of an insulation optical unit of OPGW, which comprises a metal strand removing tool, a framework and a protective sleeve. The metal strand removing tool is used for removing all the metal strands of a segment of OPGW led down along a tower, so that the led-down OPGW forms upper and lower stranding parts, and the part of the insulation optical unit between the upper and lower stranding parts is exposed. The outer side of the framework is provided with a channel for clamping the exposed part of the insulation optical unit between the upper and lower stranding parts. The protective sleeve wraps the framework, the lower end of the upper stranding part and the upper end of the lower stranding part. The framework has an insulation part and / or the protective sleeve has an insulation part. The application makes the leading-down process of OPGW safe and efficient, and completes the connection of the optical fiber network quickly and at low cost. In addition, the OPGW realizes segmented insulation and single-point grounding, effectively supports energy saving and consumption reduction of power lines and OPGW ice melting.
