Cable specimens with novel layouts -previously defined through simulations of models with increased or decreased conductor cross-sections and suitable combinations of insulation material properties and dimensions- will be tested at the premises of the High Voltage Laboratory of NTUA.
Aim of the tests will be to verify whether these cable structure scenarios achieve higher transmission capacity and insulation operating voltage. Additionally, samples of lead-free wet-design HVDC and High-Power cables will be subjected to humidity conditioning in the lab and the resulting deterioration will be quantified by measuring various properties with emphasis on DC breakdown testing.
