Abstract

The imported wall bushings used in the valve hall of the early 800 kV UHVDC transmission in China has some operation quality problem and structure design defect. The mutual contradiction between electrical performance reliability and mechanical strength design

manufacturing process and cost control makes the design and manufacture of ultra-high voltage DC wall bushing become a worldwide problem. For solving this problem

the idea of developing a capacitive composite insulated DC bushing is proposed in this paper. The main design ideas of this kind of bushing are briefly introduced with aim of facilitating its fast development.
