Abstract (en)
[origin: EP0803881A1] The fast switch (D) lies in series with the line and a semi-fast switch (d) is placed in the parallel section in series with the polymer elements (P1- P4). The matrix of these elements has an oblong cross-section and is enclosed by fluoride polymer. The metal conductors within each element extend beyond the matrix and are interconnected either on the same side (C!,C2, C3) of the assembly or on alternate opposite sides. The impregnated polymer has a resistivity of about 1 OMEGA cm. Each element is about 1000 mm long and within each element the conductors are about 10 mm apart. The assembly is held rigid by insulating bands (B1, B2).
