Abstract (en)
[origin: EP2023353A2] The device has a deflector (12), and an annular space (14) provided between the deflector and a central part (31) of a synthetic insulating material (13) surrounding a central conductor (11). A thickness of the annular space is higher than or equal to 10 millimeter, and the space is filled with a dielectric fluid i.e. sulphur hexafluoride. Reinforcement fibers (15) i.e. glass fabric, are placed around the deflector. The synthetic insulating material is thermosetting resin type polymer material, thermoplastic resin type polymer material or elastomer.
