Abstract
1389335 Electrical installations SUMITOMO ELECTRIC INDUSTRIES Ltd 30 May 1972 [12 June 1971] 25277/72 Heading H2C An inductive radiotransmission line comprises at least two transmission pairs 1, 2 with a succession of crossover transpositions at, e.g. 4, 5, with equal transposition distance P, but at different locations for each transmission pair. Conductor supports 3 are located between crossing points 4, 5 at intervals P/2 and comprises a pair of metal frames 6 having a channel portion in which is placed an insulator spacer 7 of synthetic material, e.g. polyethylene, have parallel grooves which support conductors 11, 12, 11
