Epoxy resins crosslinked with acid anhydride hardeners are widely used in high voltage insulation. They have excellent dielectric, electrical and mechanical properties up to relatively high temperatures. However, neat epoxy systems exhibit low thermal conductivity and unsuitable coefficient of thermal expansion (CTE) when used with metallic materials such as high voltage conductors.

To connect the different points of the network, the transmission and distribution of electric power used cables. Since few years, cables and especially their insulation part are evolving, going from paper insulation to a synthetic insulation. Nowadays, the insulation part of HVDC cables is in crosslinked polyethylene or XLPE.

Toward deeper submarine cable installations

Numerous High Voltage Direct Current (HVDC) submarine cables have been installed in Europe and more are yet to come. Such transmission allows the trading of energy or the supply of isolated areas with almost no limitations on distance (typically 100-1000km). Interconnections such as NorNed and soon Nord Link and North Sea Link will provide a safe path for the large integration of renewable energies in northern Europe (Figure 1).

Electricity networks of the future are moving towards supergrid networks. These networks will use HVDC voltage to supply center of consumption from sources that are far from them or to connect different countries together. The objective is to ensure network stability and security, especially with contribution renewable energies like large offshore wind farms and solar plants.
