Abstract: 1392607 Electric couplings MAXAM SWITCHGEAR Ltd 27 June 1972 [27 Oct 1971] 49852/71 Heading H2E Adjacent and abutting bus-bars are joined using bolts 21 and 23, Fig. 2, and fishplates 20 and 22, the fishplates and/or the bus-bars being slotted so that the bolts may be inserted in the bus-bar ends or in the fishplates before the fishplates are positioned on the bus-bars, thus facilitating the assembly of closely spaced lengths of bus-bar. Bus-bars carrying currents of similar phase are connected by bridging fishplates 24 and 25, joints between the second and third pairs of bus-bars being made at spaced locations along the bus-bar system. In the joint shown in Fig. 3 bolts are inserted in holes 26 in the fish plate 20 which is then placed over the end of one bus-bar e.g. 10, the appropriate bolt being pushed into one of the slots 27. The second bus-bar 10a is then brought up to the first, the appropriate bolt is pushed into the second slot 27 and all the bolts are tightened. This is repeated for the bus-bars 11 and 11a after which the fish plate 22 is secured in similar fashion. In an alternative arrangement, the fishplates 20 are formed with slots transverse to the length of the bus-bars, the bolts then being retained in elongated holes in the ends of the bus-bars. The fishplates are placed on the ends of the bus-bars from a direction transverse to the bus-bar's length. Nuts may be permanently retained on the bolts by peening over the end of the bolt or by inserting a split pin. The conductors 10 to 15 are covered with a layer of insulating material, e.g. P.V.C. or can have an insulating sleeving of Bakelite (R.T.M.) or P.V.C. which is removed in the region of a joint.
