摘要
介绍日本、法国及德国超高压干式电缆（XLPE、LDPE）的发展及在超高压电缆线路工程中的应用。简述超高压干式电缆技术的发展。对我国近年来在水电站工程中采用的超高压电缆做了叙述。
The paper outlines developments and applications of dry type insulated EHV cables in some advanced industrial countries. The details about the improvements on manufacture techniques, insulation materials, partial discharge tests and quality controls are presented, specially on XLPE insulated and LDPE insulated EHV cables. Some cases about the applications of XLPE insulated and LDPE insulated EHV cables in hydro power engineerings in China are described in the paper.
