Development of HVDC XLPE cable system for VSC and LCC

In this paper, our development results have been described in detail for HVDC XLPE cable system for various voltage ratings; insulation material at laboratory, miniature cable for the evaluation of characteristics and finally the design of full scaled power cable system including necessary joints. In the anticipation of the global market growth in near future, it has been inspired to provide the diversity of our products. For this purpose, we started with developing ±80kV cable system in 2010 and LCC/VSC type full scaled cables have been developed for those four operating voltages such as ±80kV, ±150kV, ±250kV and ±320kV. The space charge measurement system has been constructed and the space charge in ±525kV full size cable has been successfully measured for the first time in Korea. Furthermore, the development of ±525kV for both types has been now undergoing and would require a couple of years more.
