The width of two conductors 10 of one row p1 is set as 8.5mm and 7.5mm, and the width of two conductors 10 in second row p2 is set as
7.5mm and 8.5mm, the thickness of all conductors 10 are selected as 2.8mm, i.e., by a wide conductor 10 and a narrow conductor 10
Simultaneously with narrow side phase, it is arranged side by side and constitutes first row p1, same another wide conductor 10 and another narrow conductor 10 are also with this
Mode constitutes second row p2 side by side.Can occur in use showing for the dislocation of inner conductor 10 to avoid electromagnetic wire product in this way
As improving stability when electromagnetic wire uses.
In addition, 4 conductors 10 are made of rectangle copper strap wire, and the quadrangle of rectangle copper strap wire is fillet, and every rectangle copper is flat
Line is a copper strap wire continuously through the soft state of full annealing, and the content of Cu+Ag is more than or equal to 99.90%, and oxygen content≤
