PURPOSE:To obtain a better impact proofing voltage property by sequentially connecting one to the other of a pair of winding layers in series between the initial end of the former and the final end of the latter in the order different from the parallel connection. CONSTITUTION:A cylindrical winding layer is composed of two insulated winding elements 11 and 12. The initial end 11a of the element 11 is connected to an insulated coil element of the inner winding layer while the final end 11b thereof is connected to an initial end 12a of the other element 12 which is simultaneously wound in parallel therewith. The final end 12b of the element 12 is connected to a line terminal. Therefore, the initial end of one winding layer is connected to the fianl end of the other winding layer series in the order of A and B different from the parallel order of B and A. Such arrangement of the windings increases the series static capacity between the adjacent coil element in the winding layer and thus, this improves the potential distribution substantially when an impact voltage is applied. |
