一、前言海底电缆铠装外护层的质量好坏是影响海缆使用寿命的主要因素,因为海缆敷设的海底是一个极其复杂的海洋环境。海缆要受到外界机械的作用,海流、沙石的冲击,海洋微生物的侵蚀,以及海水和硫化氢等因素的腐蚀。以往常用黄麻、沥青作外被层,由于黄麻强度低,不耐磨,不耐腐蚀和沥青耐海水性能、耐微生
I. Preface Submarine cable armored outer sheath quality is the main factor affecting the life of the submarine cable, submarine cable laying of the sea is an extremely complex marine environment. Submarine cable to be affected by the role of external machinery, ocean currents, the impact of sand, marine microbial erosion, as well as seawater and hydrogen sulfide and other factors of corrosion. In the past commonly used jute, asphalt for the outer layer, due to low jute strength, wear resistance, corrosion resistance and asphalt resistance to sea water, resistant to micro-organisms
