摘要

所有介质自支撑(ADSS)电缆与传输线一起安装,用于通信。在安装过程中,电缆的外层是疏水的,不容易产生干带电弧。但是,随着时间的推移,这些电缆变得不那么疏水,因此容易受到干带电弧的影响。这种疏水性的损失是由于污染在外层形成的污染造成的。这是电缆故障的原因之一。由于这些电缆租赁给其他公司,一旦发生故障,将造成相当大的损失。本文给出了典型的模型,并计算了相应的电压分布和电流分布。这可以用来预测模型上的干带弧。所采用的方法考虑了ADSS电缆的垂度、跨距和污染。

Design of an All-Dielectric Self-Supporting cable System
All Dielectric Self-Supporting (ADSS) cables are installed along with transmission line for the purpose of communication. During installation the outer layer of the cable is hydrophobic and is not prone to dry band arcing. But, these cables becomes less hydrophobic over time and therefore vulnerable to dry band arcing. This loss in hydrophobicity occurs because of the contamination formed on the outer layer due to pollution. This is one of the reasons for cable failure. Considerable amount of losses will be incurred on the occurrence of a cable failure as these cables are leased to other companies. In this paper typical models are shown and their corresponding voltage distribution and current distribution are calculated. This could be used to predict dry band arcing on the models. The method used considers sag, span and pollution on the ADSS cable.
