Abstract

1468148 Coils for dynamo-electric machines C A PARSONS & CO Ltd 26 Feb 1974 [22 Dec 1972] 59450/72 Addition to 1316256 Heading H2A In the dynamo-electric machine of the parent patent, some of the strands are ducted composite strands, the high conductivity material having a resistivity of less than 3 x 10<SP>-8</SP> ohm-metre and the high mechanical strength material having a 0À2% proof stress greater than 30,000 p.s.i. The ducts may carry coolant and may be formed in the high conductivity or high mechanical strength material or in both. The high mechanical strength material may be formed as a tube of rectangular or circular cross-section, Figs. 1, 2 (not shown), having several high conductivity segments bonded to its exterior surface. The strand shown comprises six high conductivity segments 1 and a hollow tube 4 of high mechanical strength material mutually separated by insulation 3, the whole being surrounded by a low conductivity tube 7. A conductor may comprise a number of such strands arranged in a circle around a central strand.
