Abstract :
This paper discusses the relative advantages and disadvantages of self contained fluid filled cable systems and XLPE power cable systems for EHV applications (400 kV and above). The traditional technology of an impregnated laminar dielectric has provided excellent service performance over many decades. The technology has been gradually improved and refined over this period and the problems that have been experienced in the first generation of SCFF cables have been eliminated. Experience with extruded insulated cables at the distribution levels is positive. However this technology is still relatively new at the transmission voltage levels and is still developing
