Abstract

Polypropylene (PP) has been used as an innovative and, in particular, environmentally friendly base material for cable insulation in medium-voltage and high-voltage technology, with comparable or better technical properties than XLPE. PP cables are nowadays in service for voltages up to 150 kV at AC and are available for operating voltages up to ±600 kV at DC. However, the medium-voltage direct current (MVDC) technology is a promising approach to meeting the upcoming challenges in the distribution system of tomorrow due to the growing use of decentralized renewable energy sources and to enable the required energy transition. In this context, eco-friendly MVDC cables are of great importance. In this report, an overview of the general technical characteristics and environmental aspects of PP-insulated medium-voltage cables and an investigation of a MVAC PP-insulated cable for MVDC transmission are presented and discussed in detail.
