| -7- Contd. The cross sectional area of this strip = .00815 / .985 = .00827" or as much greater than this as space will allow after getting in 36 turns of 17 SWG. teazer winding per pole. Suggest in the first instance we try - (1). On each of the four poles 36 turns of 17-SWG. teazer winding plus 3 1/2 turns of main of as much section as possible. and (2). On each of two opposite poles as many 17-SWG. teazer turns as possible, and on the other two poles 7 1/2 turns of main winding of as much section as possible. ----- EFC. | ||
