Abstract
Overhead optical cable is an important framework for the power communication network. The common types of optical cables erected with power lines of 35 kV and above include optical fiber composite ground wire (OPGW), non-metallic self-supporting optical cable (ADSS) and optical fiber composite phase wire (OPPC), different types of optical cables have their own characteristics, and are suitable for different situations. This article starts with the structure of the optical cable, analyzes the characteristics of different types of optical cables, and further analyzes and compares from the perspective of electrical, economic, and maintenance. For the problems encountered during the use of different types of optical cables, the safety, The technical regulations are more comprehensively explained. This article is for operation and designer reference.
